Arachnoiditis ossifications in the spine / Aracnoidite ossificante na coluna vertebral / Aracnoiditis osificante en la columna vertebral

ABSTRACT Introduction: Arachnoiditis ossificans (AO) in the spine is a rare entity characterized by progressive calcification of the arachnoid and dural sac, with consequent neurological involvement. Objective: Review the causes, clinical manifestations, and complementary studies for their correct diagnosis. Method: Systematic review under PRISMA guidelines, with search in Pubmed, Lilacs, and Embase. Patient demographics (sex and age), history reported as a cause of AO and time elapsed between cause and diagnosis of AO, clinical manifestations, and complementary studies used for diagnosis were collected. Results: 38 articles, of which we collected 46 patients (25 women, 21 men), mean age of 52 years. The most frequent cause was previous spine surgery and myelography with fat-soluble contrast. The most frequent symptoms were insufficient muscle strength (74%) and pain (69%). CT was used in 76%. The most frequent location was thoracic (35%). Conclusion: Its pathogenesis is unclear; described as the final cause of a chronic inflammatory process in the arachnoid with the consequent bone metaplasia. Diagnosis usually precedes a long period of pain and progressive neurological symptoms. The most sensitive and specific complementary study for the diagnosis is the tomography without contrast, which should be requested in case of clinical suspicion. Level of Evidence II; Systematic Review.

CNS Tuberculosis

Tuberculosis can involve almost any organ of the body. In the Central Nervous System (CNS) it can cause meningitis, tuberculoma, abscess,spondylitis, arachnoiditis, myeloradiculitis or other manifestations. Around 10% of all patients with tuberculosis have CNS involvement. Tuberculosis is rampant in the developing world and has reemerged as a major public health menace with the HIV pandemic. Compared with HIV-negative individuals, HIVpositive individuals with TB are 5 times more likely to have CNS involvement. Laboratory confirmation of CNS TB is difficult and hence empirical treatment has to be initiated as early as possible based on clinical and radiological features. In this article,we review the CNS manifestations of tuberculosis and their diagnosis and treatment

Potential Therapeutic Benefits of Brahma Rasayana in the Management of Tuberculous Cerebrovascular Disease - A Case Report

Tuberculous meningitis (TBM) is an air-borne infectious disease caused by the bacteria Mycobacterium tuberculosis that affects the central nervous system (CNS). Among all the incident cases of TB, CNS TB represents approximately 1% with TBM as the most grievous among all. The basic pathology in TBM is the inflammation of the arachnoid membrane, the pia mater and the cerebrospinal fluid (CSF). It typically presents as mild fever, headache, anorexia and general debility that progress over one to two weeks to cause severe headache, fever, vomiting, confusion, meningismus and cranial nerve deficits. The most common complications of TBM include hydrocephalus, optico-chiasmatic arachnoiditis, seizures and stroke. Out of these, tuberculous cerebrovascular disease is a common neurological sequelae. This case study elaborates the treatment line and observations made in a 29 year old male patient who presented with hemiparesis and significant sensory deficit following an event of tuberculous meningitis. MRI brain was suggestive of basilar meningitis, optico-chiasmatic arachnoiditis, infarcts and tuberculoma with chest X-ray revealing increased bronchovascular markings in bilateral lung fields. Initially on admission, Deepana-pachana was done followed by snehapana with Shadpala ghrta and Virechana as Sodhana karma. Abhyanga, Ushma Sweda, Churna pinda sweda and Jambeera pinda sweda were successively done allied with physiotherapy. Yogavasti with Vedanasthapana gana as Kashaya and Kalka was done intervened by Anuvasana vasti. Succeedingly, Murdhni taila prayoga and Marsha nasya were also incorporated with periodical neurological, hematological and biochemical assessment. On discharge, Brahmi kalyanaka ghrta and Brahma Rasayana were advised inclusive of physiotherapy.

Arachnoiditis ossificans with syringomyelia: a unique case of myelopathy

Arachnoiditis ossificans (AO) is a rare disorder characterized by calcification of arachnoid membranes first described by Kaufman and Dunsmore in 1971. It is a very rare cause of spinal canal stenosis leading to neurological compromise presenting with progressive lower extremity myelopathy. It has been described to be a sequela of various conditions previous intradural surgery, myelograms, vascular malformations and adhesive arachnoiditis. Associated conditions may include syringomyelia. The imaging findings on MRI may be confusion. Preferred diagnostic method is non contrast computed tomography (CT). Surgical intervention is still controversial and can include decompression. The authors report the case of 48 years female presenting with gradually progressing paraparesis. Magnetic resonance imaging of the spine revealed a spinal cord syrinx but with an extramedullary intradural hypo-intensity. A computed tomography scan clearly demonstrated the abnormality and its extent. We present a unique case of syringomyelia resulting from spinal arachnoiditis ossificans and review the relevant literature. This case reports a unique presentation of arachnoiditis ossificans with syringomyelia in which etiology is not clear. We also highlight the difficulty is diagnosis on MRI and need of non-contrast CT.

A rare cause of progressive neuropathy: Arachnoiditis ossificans

Arachnoiditis ossificans (AO) is a rare type of chronic arachnoiditis characterized by the presence of calcification or ossification of the spinal arachnoid which is usually associated with progressive neurological deficits. It is usually followed by prior history of trauma, surgery, infection, or myelography. Magnetic resonance imaging and computed tomography are the characteristics that are helpful in the diagnosis of most cases. Prognosis and treatment depends on the site and clinical presentation of the patients. We present a case of a young female who presented with a long-standing history of neurological symptoms and a intradural lesion mimicking a tumor.

Cauda Equina Syndrome Occurred by Adhesive Arachnoiditis of the Lumbar Spine with an Unknown Cause / 대한정형외과학회잡지

Spinal adhesive arachnoiditis is an inflammation and fibrosis of the subarachnoid space and pia mater caused by infection, trauma, spinal vascular anomalies, and iatrogenic (surgery and/or puncture). Adhesive arachnoiditis develops various symptoms and signs (gait disturbances, radiating pain, paralysis, and incontinence). On the other hand, adhesive arachnoiditis associated with cauda equina syndrome has not been reported in Korea until now. The authors experienced cauda equina syndrome caused by adhesive arachnoiditis of the lumbar spine with satisfactory results following decompression. We report this case with a review of the relevant literature.

Tuberculous optochiasmatic arachnoiditis and optochiasmatic tuberculoma in Malaysia

@#Background & Objectives: Arachnoiditis which involves the optic chiasm and optic nervecan rarely occurs in the patients with tuberculous meningitis (TBM). The primary objective of this study was to determine the incidence, assess the clinical and neuroimaging findings, and associations, understand its pathogenesis of these patients, and determine its prognosis. Methods: The patients admitted with TBM in the neurology wards of two tertiary care hospitals from 2009 to 2017 in Kuala Lumpur, Malaysia were screened. The patients with OCA and optochiasmatic tuberculoma were included in this study. We assessed the clinical, cerebrospinal fluid (CSF), imaging findings of the study subjects and compared with other patients without OCA or optochiasmatic tuberculoma. Results: Eighty-eight patients with TBM were seen during the study period. Seven (8.0%) had OCA and one (1.1%) had optochiasmatic tuberculoma. Five out of seven (71.4%) patients with OCA were newly diagnosed cases of TBM. The other two (28.6%) had involvement while on treatment with antituberculous treatment (paradoxical manifestation). The mean age of the patients with OCA was 27.3 ± 11.7. All the OCA patients had leptomeningeal enhancement at other sites. All had hydrocephalus and cerebral infarcts on brain neuroimaging. Three (42.9%) patients had cerebral tuberculoma at sites other than suprasellar and optic chiasm areas. On univariate analysis, the presence of OCA and optochiasmatic tuberculoma was associated with raised CSF opening pressure (p=0.014), younger age (p=0.024), cerebral infarcts (p=0.018) and hydrocephalus (p= 0.046). There was no statistically significant association on logistic regression. Only one (14.3%) patient had visual impairment. Conclusion: OCA and optochiasmatic tuberculoma were seen in 9% of a cohort of Malaysian TBM patients. They were more likely to be younger, have raised CSF opening pressure, cerebral infarcts and hydrocephalus, suggesting the association with a more severe exudative disease.

Thecaloscopy: a novel method in spine surgery / Tecaloscopia: um novo método na cirurgia de coluna / Tecaloscopia: un nuevo método en la cirugía de la columna vertebral

ABSTRACT Objetive: Thecaloscopy is a less invasive method of exploration of the spinal subarachnoid space, using an ultra-thin, flexible endoscope and endoscopic fenestration of scars and adhesions. Thecalopscopy was used in Russian neurosurgery for the first time. Methods: Since 2009, we have operated on 32 patients with the following diagnoses: 17 - spinal adhesive arachnoiditis (8 - local forms, 9 - diffuse forms), 12 - spinal arachnoid cysts (7 - post-traumatic cysts, 5 - idiopathic cysts), and 3 - extramedullary tumors (thecaloscopic videoassistance and biopsy). In all cases, we performed exploration of subarachnoid space and pathologic lesion with endoscopic perforation of the cyst or dissection of adhesions using special instrumentation. The mean follow-up time in our group was 11.4 months. Results: Neurological improvement (mean 1.4 by the modified Frankel scale, 1.8 by the Ashworth spasticity scale) was seen in 87% of patients operated for spinal arachnopathies. Temporary neurological deterioration (mild disturbances of deep sensitivity) was seen in 9% of patients and managed successfully with conservative treatment. One patient (3.1%) was operated three times due to relapse of adhesions. There were no serious intraoperative complications (e.g. severe bleeding or dura perforation). Postoperative complications included one CSF leakage and one case of postoperative neuralgic pain. The mean hospitalization time was 7.6 days. Conclusion: According to our data, we conclude that thecaloscopy is efficient and safe method, and should be widely used for spinal arachnopathies, adhesive arachnoiditis and arachnoid cysts. Taking into account that adhesive spinal arachnoiditis is a systemic process, and that spinal arachnoid cysts may also be extended, thecaloscopy may be regarded as the most radical and less-invasive form of surgical treatment that currently exists in neurosurgery.

RESUMO Objetivo: A tecaloscopia é um método menos invasivo de exploração do espaço subaracnóideo, com um endoscópio flexível ultrafino e fenestração endoscópica de cicatrizes e aderências. A tecaloscopia foi usada pela primeira vez na neurocirurgia russa. Métodos: Desde 2009, operamos 32 pacientes com os seguintes diagnósticos: 17 aracnoidites adesivas espinais (8 formas locais e 9 formas difusas), 12 cistos aracnóideos espinais (7 cistos pós-traumáticos e 5 cistos idiopáticos) e 3 tumores extramedulares (vídeo-assistida por tecaloscopia e biópsia). Em todos os casos, realizamos a exploração do espaço subaracnóideo e da lesão com perfuração endoscópica do cisto ou dissecção de aderências usando instrumentação especial. O acompanhamento médio em nosso grupo foi de 11,4 meses. Resultados: A melhora neurológica (média 1,4 pela escala de Frankel modificada e 1,8 pela escala de espasticidade de Ashworth) foi observada em 87% dos pacientes operados devido a aracnopatias da coluna vertebral. A deterioração neurológica temporária (distúrbios leves da sensibilidade profunda) foi observada em 9% dos pacientes que foi tratada com sucesso pelo método conservador. Um paciente (3,1%) foi operado três vezes devido à recorrência de aderências. Não houve complicações intraoperatórias graves (por exemplo, sangramento grave ou perfuração da dura-máter, etc.). As complicações pós-operatórias incluíram um extravasamento de LCE e um caso de neuralgia pós-operatória. O período médio de hospitalização foi de 7,6 dias. Conclusão : De acordo com nossos dados, concluímos que a tecaloscopia é um método eficiente e seguro, e deve ser amplamente utilizado para aracnopatias espinais, aracnoidites adesivas e cistos aracnóideos. Considerando que a aracnoidite adesiva é um processo sistêmico e que os cistos aracnóideos da coluna vertebral também podem ser extensos, a tecaloscopia pode ser considerada como a forma mais radical e menos invasiva de tratamento cirúrgico existente atualmente em neurocirurgia.

RESUMEN Objetivo: La tecaloscopia es un método de exploración menos invasivo del espacio subaracnoideo con un endoscopio flexible ultrafino y fenestración endoscópica de cicatrices y adherencias. La tecaloscopia se utilizó en neurocirugía rusa por primera vez. Métodos: Desde 2009 operamos 32 pacientes con los siguientes diagnósticos: 17 aracnoiditis adhesivas espinales (8 formas locales y 9 formas difusas), 12 quistes aracnoideos espinales (7 quistes postraumáticos y 5 quistes idiopáticos) y 3 tumores extramedulares (asistida por video tecaloscópico y biopsia). En todos los casos se realizó la exploración del espacio subaracnoideo y lesión con perforación endoscópica del quiste o disección de adherencias mediante instrumentación especial. El seguimiento medio en nuestro grupo fue de 11,4 meses. Resultados: La mejoría neurológica (media 1,4 por la escala de Frankel modificada y 1,8 por la escala de espasticidad de Ashworth) se observó en el 87% de los pacientes operados debido a aracnopatías de la columna vertebral. Se observó deterioro neurológico temporal (alteraciones leves de la sensibilidad profunda) en el 9% de los pacientes, que fue tratada con éxito por el método conservador. Un paciente (3,1%) fue operado tres veces debido a la recurrencia de las adherencias. No hubo complicaciones intraoperatorias graves (por ejemplo, sangrado grave o perforación de la duramadre, etc.). Las complicaciones postoperatorias incluyeron una extravasación del LCR y un caso de neuralgia postoperatoria. El período promedio de hospitalización fue de 7,6 días. Conclusiones : De acuerdo con nuestros datos, concluimos que la tecaloscopia es un método eficiente y seguro, que debe ser ampliamente utilizado para aracnopatías espinales, aracnoiditis adhesivas y quistes aracnoideos. Teniendo en cuenta que la aracnoiditis adhesiva es un proceso sistémico y que los quistes aracnoideos de la columna vertebral también pueden ser extensos, la tecaloscopia puede ser considerada como la forma más radical y menos invasiva de tratamiento quirúrgico existente actualmente en neurocirugía.

Neurocisticercosis racemosa (sic), diagnóstico orientado por neuroimágenes / Racemose neurocysticercosis: Neuroimaging guides the diagnosis

Resumen La neurocisticercosis es la primera causa de parasitosis del sistema nervioso central y de epilepsia adquirida en países en desarrollo. Sus manifestaciones clínicas, especialmente de la variante racemosa (sic), son pleomorfas e inespecíficas, características que hacen de su diagnóstico un desafío para el clínico. El objetivo de este informe fue describir dos casos de neurocisticercosis racemosa (sic), en los cuales las neuroimágenes permitieron hacer el diagnóstico definitivo. El primer caso se trató de una paciente con cefalea persistente y signos neurológicos focales, que requirió múltiples exámenes paraclínicos para, finalmente, llegar al diagnóstico definitivo de neurocisticercosis racemosa (sic) con vasculitis cerebral secundaria. A pesar del tratamiento médico y quirúrgico, la paciente falleció después de diversas complicaciones. El segundo caso se trató de una paciente con antecedentes de neurocisticerosis, que consultó por vómito crónico incoercible y, también requirió múltiples exámenes paraclínicos para concluir que se trataba de un vómito de origen central, secundario a neurocisticercosis racemosa (sic) y obstrucción del cuarto ventrículo. Después del tratamiento médico y quirúrgico, la paciente presentó una leve mejoría. En estos dos casos se evidenció que la adecuada interpretación de las neuroimágenes es fundamental para el diagnóstico de la neurocisticercosis racemosa (sic).

Abstract Neurocysticercosis is the leading cause of parasitosis of the central nervous system and acquired epilepsy in developing countries. The clinical manifestations of neurocysticercosis, especially its racemose variant, are pleomorphic and unspecific, characteristics that hinder the diagnosis and make it a challenge for the clinician. The objective of this report was to describe two cases of racemose neurocysticercosis in which neuroimaging led to the definitive diagnosis. The first case involved a patient with persistent headache and focal neurological signs. She required multiple paraclinical tests that led to the definitive diagnosis of racemose neurocysticercosis with secondary cerebral vasculitis. Despite medical and surgical treatment the patient died after multiple complications. The second case involved a patient with a history of neurocysticercosis, who consulted for chronic intractable vomiting. She required multiple paraclinical tests that led to the diagnosis of vomiting of central origin secondary to racemose neurocysticercosis and entrapment of the fourth ventricle. After medical and surgical treatment the patient showed slight improvement. In these two cases it was evident how proper interpretation of neuroimages is essential for the diagnosis of racemose neurocysticercosis.

Intradural Extramedullary Capillary Hemangioma In the Upper Thoracic Spine with Simultaneous Extensive Arachnoiditis

Capillary hemangiomas are common benign vascular tumors on skin and soft tissues, but developing as an intradural and extramedullary (IDEM) tumor in spine is extremely rare. In this report, we present IDEM tumor compressing thoracic cord in T2–3 level with extensive arachnoiditis below the tumor level in a 60-year-old man. The lesion was removed and histological diagnosis was capillary hemangioma. Prompt diagnosis and resection are important to avoid neurological deterioration from acute hemorrhagic condition. Simultaneous arachnoiditis may be originated from old subarachnoid hemorrhage associated tumor before diagnosis, and we suggest it as a helpful diagnostic feature to suspect vascular tumors such as capillary hemangioma.

Case Report of Epstein–Barr Virus (EBV) Meningitis with Arachnoiditis in a Previously Healthy Patient.

Epstein-Barr virus (EBV) is from herpesviridae family that is spread by close contact between susceptible persons and asymptomatic EBV carriers. EBV is the most common causative agent of infectious mononucleosis (IM), that persists asymptomatically for life in nearly all adults. It is associated with the development of B cell lymphomas, T cell lymphomas, Hodgkin lymphoma and nasopharyngeal carcinomas in certain patients. EBV is associated with a variety of CNS complications which can occur in the absence of clinical or laboratory manifestations of infectious mononucleosis. EBV meningoencephalitis should always be considered as one of the causative agents in immunocompetent patients who present with clinical features of meningitis. Molecular diagnostic techniques using CSF PCR and blood samples provides prompt diagnosis. Neuroimaging with MRI provides neuroanatomic localization of EBV meningoencephalitis, which may be a prognostic factor. The purpose of this case report is to increase the awareness of health care professionals about EBV meningoencephalitis as an under-diagnosed disease, and emphasize that excellent outcome can be achieved by early treatment. In this case report, we review a young male, with no significant past medical history, who presented with acute EBV meningitis, and was successfully treated medically.

Hydrocephalus due to Membranous Obstruction of Magendie's Foramen

We report a case of non communicating hydrocephalus due to membranous obstruction of Magendie's foramen. A 37-year-old woman presented with intracranial hypertension symptoms caused by the occlusion of Magendie's foramen by a membrane probably due to arachnoiditis. As far as the patient's past medical history is concerned, an Epstein-Barr virus infectious mononucleosis was described. Fundoscopic examination revealed bilateral papilledema. Brain magnetic resonance imaging demonstrated a significant ventricular dilatation of all ventricles and turbulent flow of cerebelospinal fluid (CSF) in the fourth ventricle as well as back flow of CSF through the Monro's foramen to the lateral ventricles. The patient underwent a suboccipital craniotomy with C1 laminectomy. An occlusion of Magendie's foramen by a thickened membrane was recognized and it was incised and removed. We confirm the existence of hydrocephalus caused by fourth ventricle outflow obstruction by a membrane. The nature of this rare entity is difficult to demonstrate because of the complex morphology of the fourth ventricle. Treatment with surgical exploration and incision of the thickened membrane proved to be a reliable method of treatment without the necessity of endoscopic third ventriculostomy or catheter placement.

Surgical Outcome of Tuberculous Myelitis, Arachnoiditis and Spondylitis after Brain Meningitis: A Case Report

STUDY DESIGN: A case report. OBJECTIVES: To report a rare case of a surgically treated tuberculous myelitis and arachnoiditis patient with incomplete paraplegia. SUMMARY OF LITERATURE REVIEW: Tuberculous myelitis and arachnoiditis is a rare disease with a high rate of neurologic deficit. This condition is treated using antituberculous medication and high-dose steroid therapy, but surgical treatment has rarely been reported and the outcomes vary. MATERIAL AND METHODS: A 29-year-old female had tuberculous myelitis and arachnoiditis. The patient was treated with antituberculous medication and high-dose steroid therapy, but the treatment failed and the patient could not walk because of incomplete paraplegia. The surgical treatment was performed twice; we decompressed by total laminectomy and debrided the infected arachnoid membrane. Four months after surgery, we performed anterior interbody fusion due to the development of spondylitis with kyphosis. RESULTS: Three years after the first operation, the patient's neurologic state improved and she could walk 90 m without assistance. CONCLUSIONS: Here, we report a very rare case of surgically treated tuberculous myelitis and arachnoiditis and provide a treatment option for this condition to spine surgeons.

Arachnoiditis Following Caudal Epidural Injections for the Lumbo-Sacral Radicular Pain

Caudal epidural steroid injection is a very common intervention in treatment of low back pain and sciatica symptoms. Although extensively used, it is not devoid of complications. A few reports of chemical and infective arachnoiditis exist following lumbar epidural anaesthesia, but none following a caudal epidural steroid injection.We report a case of arachnoiditis following caudal epidural steroid injections for lumbar radiculopathy. The patient presented with contralateral sciatica, worsening low back pain and urinary retention few days following the injection, followed by worsening motor functions in L4/L5/S1 myotomes with resultant dense foot drop. Gadolinium-enhanced magnetic resonance imaging suggested infective arachnoiditis with diffuse enhancement and clumping of the nerve roots within the lumbar and sacral thecal sac. As the number of injections in the management of back pain and lumbo-sacral radicular pain is increasing annually, it is imperative to have a thorough understanding of this potentially dangerous complication and educate the patients appropriately.

Aracnoiditis postanestesia raquídea para cesárea / Arachnoiditis Following Spinal Anesthesia for Cesarean Section

Se reporta un caso de aracnoiditis tras anestesia subaracnoidea para cesárea que cursa con paraparesia, dolor lumbar e hipertensión arterial. Al paciente se le diagnostica aracnoiditis con criterios clínicos e imaginológicos 8 días después de recibir anestesia subaracnoidea para cesárea. Presenta emergencia hipertensiva, se descarta preeclampsia posparto. Posiblemete esta presentación se relacione con inhibición de centros reguladores medulares. Se trató con dexametasona sistémica. La paciente presenta recuperación completa de sus síntomas en el curso de 10 días, sin recaídas en más de 1 año de seguimiento.

We report a case of arachnoiditis following subarachnoidal anesthesia for Cesarean section, with paraparesis, lumbar pain and arterial hypertension. The patient was diagnosed with arachnoidits on the basis of the clinical and imaging findings eight days after receiving subarachnoidal anesthesia for a C-section. She presented with emergent hypertensive crisis, and post-partum pre-eclampsia is ruled out. This presentation might be related with the inhibition of spinal regulatory centers. She was treated with systemic dexamethasone. The patient was totally symptom-free within 10 days and went on to recover fully and has been well during more than one year of follow-up.

A Case of Tuberculous Optochiasmatic Arachnoiditis / 대한내과학회지

Tuberculous optochiasmatic arachnoiditis (OCA) is a rare complication of tuberculous meningitis. We describe a 47-year-old female with tuberculous OCA confused with ethambutol-associated optic neuropathy. She was on anti-tuberculous treatment (i.e., isoniazid, rifampin, ethambutol, and pyrazinamide) for two months due to tuberculous meningitis. Visual impairment occurred during treatment, and ethambutol was changed to levofloxacin because of concern for ethambutol-associated optic neuropathy. Her visual impairment did not improve three months after anti-tuberculous treatment that excluded ethambutol, and she was referred to our hospital. Brain MRI showed enhancement of the optic chiasm and bilateral optic tract, and fundoscopy revealed bilateral optic nerve atrophy, suggesting tuberculous OCA. Her visual acuity was partially improved after anti-tuberculous treatment. Tuberculous OCA should be considered in addition to ethambutol-associated optic neuropathy for a patient with tuberculous meningitis who presents with visual impairment.

Bayle e a descrição da aracnoidite crônica na paralisia geral: sobre as origens da psiquiatria biológica na França / Bayle y la descripción de la aracnoiditis crónica en la parálisis general: sobre los orígenes de la psiquiatría biológica en Francia / Bayle et la description de l'aracnites chronique dans la paralysie générale: sur les origines de la psychiatrie biologique en France / Bayle and the description of chronic arachnoiditis in general paralysis: on the origins of biological psychiatry in France

A tese de medicina defendida em 1822, em Paris, por Antoine-Laurent Bayle, intitulada “Pesquisas sobre as doenças mentais”, constitui um momento de virada na história das concepções biológicas em psicopatologia. Apoiado sobre um método anátomo-clínico rigoroso. Bayle apresenta seis observações clínicas de pacientes com uma história crônica e progressiva de comportamento exaltado, idéias de grandeza, de poder e de ambição que se transformam no final de algum tempo em delírios maníacos com agitação psicomotora. Simultaneamente, vai-se instalando um quadro de paralisia progressiva de vários grupos musculares, chegando até a incapacidade física extrema. Na fase terminal, os pacientes apresentam uma condição tipicamente demencial e de profundo comprometimento corporal, que os conduz à morte. Ao exame cadavérico, Bayle constatou a presença sistemática de uma inflamação crônica das meninges cerebrais (aracnoidite crônica) à qual ele atribui o fundamento biológico dos sintomas observados. Dessa forma. Bayle realiza uma descrição clínica rigorosa de uma entidade psicopatológica típica, de evolução crônica e progressiva e demonstra sua relação com uma lesão cerebral específica e objetivamente demonstrável. Tal descoberta, inicialmente recebida com muitas reservas, constituiria posteriormente uma espécie de paradigma para a pesquisa e para o projeto teórico e terapêutico para a psiquiatria biológica que começava a se organizar na França ao longo do século XIX.

Antoine Laurent Bayle’s medical thesis, entitled “Studies on mental diseases” and defended in Paris in 1822, represented an important advance in the history of biological conceptions in psychopathology. Based on a rigorous anatomic and clinical method, Bayle presented clinical observations on six patients with chronic and progressive histories of exalted behavior and ideas of grandeur: power and ambition, a condition that eventually evolved to maniac delusion with psychomotor agitation. Simultaneously, a situation of progressive paralysis of several muscle groups set in, leading to extreme physical incapacity. In the final stage the patients showed a typically demential condition with serious physical impairment which led to death. Post-mortem examinations showed the presence, is all cases, of chronic inflammation of the cerebral meninges (chronic arachnoidits), which Bayle held to be the biological basis of the symptoms noted. Bayle thus provided a rigorous clinical description of typical psychopathological entity with chronic and progressive evolution, and showed its relationship to specific and objectively demonstrable cerebral damage. This discovery, first received with considerable reservation, later served as a type of paradigm for research and for the theoretical and therapeutic project for biological psychiatry that began in France during the 19th century.

Fondé sur une méthode anatomoclinique rigoureuse, Bayle y présente six observations cliniques de patients ayant une histoire chronique et progressive de comportement exalté, idées de grandeur, de puissance et d'ambition qui se transforment au bout d'un certain temps en délires maniaques accompagnés d'agitation psychomotrice. Simultanément, un tableau de paralysie progressive de plusieurs groupes musculaires se met en place, allant jusqu'à l'incapacité physique extrême. Dans la phase terminale, les patients présentent une condition typiquement démentielle et de profond affaiblissement corporel, finissant par en mourir. À l'examen cadavérique, Bayle a constaté la présence systématique d'une inflammation chronique des méninges cérébrales (arachnites chronique) à laquelle il attribue le fondement biologique des symptômes observés. Bayle nous fournit ainsi une description clinique rigoureuse d'une entité psychopathologique typique à l'évolution chronique et progressive et démontre son rapport à une lésion cérébrale spécifique et objectivement démonstrable. Telle découverte, reçue avec beaucoup de réserves au départ, constituera ensuite une sorte de paradigme pour la recherche et pour le projet théorique et thérapeutique de la psychiatrie biologique qui commençait à s'organiser en France au cours du XIX siècle.

Neurolisteriosis: descripción de siete casos / Neurolisteriosis: description of seven cases

Listeria Monocytogenes is a gram-positive Bacillus that affects immunocompromised patients, newborn, pregnant women and persons over 65 years. Infection is acquired through contaminated food. The Bacillus has predilection for the central nervous system. Its presents most commonly as an acute meningitis, it also presents as a chronic meningitis, cerebritis, rhomboencephalitis, brain and spinal abscess. Diagnosis for L. monocytogenes is made through positive cultures in blood and cerebrospinal fluid (CSF). Magnetic Resonance (MR) also helps to in the diagnosis of neurolisteriosis lesions. We described seven cases with L. Monocytogenes infection during 2007 and 2008, with four cases over the aged of 65 years old. Five presented acute meningitis; two rhomboencephalitis and one patient had meningoencephalitis. Six cases showed inflammatory CSF with pleocytosis with polymorphonuclear prevail and normal glycorrachia. MR showed inflammatory findings in five patients and focal brainstem lesions in two cases, one had acute hydrocephalus due arachnoiditis. Five patients improve clinically and two fatal cases were described. Listeriosis is the third cause of meningitis and should be consider in the differential diagnosis of meningitis with clear fluid, especially with pleocytosis and normal glycorrachia. Other clues of the diagnosis are dizziness with or without nystagmus and brainstem compromise. Arachnoiditis should be avoided with steroidal use. The diagnostic imaging test of choice for brain stem compromise is MR.

La Listeria Monocytogenes es un bacilo Gram-positivo que afecta a pacientes inmunocomprometidos, a niños, embarazadas y personas mayores de 65 años. El modo de adquirirla es la ingestión de alimentos contaminados. El bacilo tiene predilección por el sistema nervioso central, donde su expresión más frecuente es la meningitis aguda, también puede presentarse como meningitis crónica, cerebritis, rombencefalitis, abscesos cerebrales y espinales. El cultivos positivos de L. monocytogenes en muestras de sangre o líquido cefalorraquídeo, permite confirmar el diagnóstico. La Resonancia Magnética de cerebro también contribuye al diagnóstico de las lesiones por neurolisteriosis. Se analizan siete casos de neurolisteriosis ocurridos los a±os 2007 y 2008, entre ellos cuatro pacientes mayores de 65 años. La meningitis aguda fue la forma de presentación en cinco de ellos, dos evolucionaron como rombencefalitis y uno como meningoencefalitis. El LCR fue inflamatorio en seis de los pacientes, con pleocitosis depredominio polinuclear, pero glucorraquia normal. La RM mostró imágenes de aspecto inflamatorio en cinco de los enfermos, dos de ellos tenían lesiones focales del tronco cerebral, uno hizo un hidrocéfalo agudo por aracnoiditis. Cinco pacientes presentaron una evolución clínica favorable y dos fallecieron. Siendo la listeriosis la tercera causa etiológica de meningitis, debe ser considerada en el diagnóstico diferencial de meningitis a líquido claro, especialmente en LCR con abundantes polinucleares y glucosa en rangos normales. Otras claves son la sensación vertiginosa con o sin nistagmus y el compromiso de nervios craneales de origen protuberancial. Debe prevenirse las aracnoiditis con el uso precoz de corticoides. Es obligatorio el estudio con RM en toda sospecha de neurolisteriosis.

A Case of Paraplegia Associated with Epidural Anesthesia: A case report / 대한통증학회지

Paraplegia is a relatively rare complication of epidural anesthesia. Several possible factors may contribute to the development of paraplegia including arachnoiditis, trauma and ischemia. We experienced a case where paraplegia had developed after epidural anesthesia for cesarean section. So we present the case and consider the possible etiologies. A 30-year-old previously healthy woman was referred to our hospital for postpartum motor weakness of the lower limbs. Six days prior, the patient was admitted at a local obstetric clinic for delivery at 39 weeks gestation. The patient underwent a Cesarean section under epidural anesthesia induced with 20 ml 2% lidocaine and 5 ml 0.5% bupivacaine. In the early morning of the day following the Cesarean section, a motor and sensory deficit in both lower extremities was noted. A lumbar MRI showed diffuse enhancement along the cauda equina and spinal cord surface in the lower lumbar spine, suggesting diffuse arachnoiditis.
