ABSTRACT

RESUMEN En muchas ocasiones, los pacientes con tumores cerebrales tienen una variedad de síntomas psiquiátricos inespecíficos. Algunos de estos pueden constituir la primera o única manifestación del tumor, sin la presencia de ningún síntoma o signo neurológico. El diagnóstico ha de basarse en la anamnesis completa y en la exploración neurológica; la neuroimagen confirmará el diagnóstico clínico. Con el presente trabajo se describió la asociación inusual de hematoma subdural crónico y meningioma parasagital en un caso presentado. Se trató de un paciente de 68 años con antecedentes de esquizofrenia. Acudió a consulta con una hemiparesia izquierda. Se le realizó una tomografía axial computarizada de cráneo y arrojó un hematoma subdural crónico y un meningioma parasagital derecho. Se le aplicó tratamiento quirúrgico en dos tiempos operatorios. Su evolución posquirúrgica transcurrió sin complicaciones (AU).


ABSTRACT In many cases, patients with brain tumors have a variety of nonspecific psychiatric symptoms. Some of them can be the first or the only manifestation of the tumor, without presenting any neurological signs or symptoms. The diagnosis must be based on the complete anamnesis and on the neurological examination. The neuroimaging will confirm the clinical diagnosis. The unusual association of a chronic subdural hematoma and a parasagittal meningioma was described in a case presented in the current work. It dealt with a patient, aged 68 years with antecedents of schizophrenia. He assisted the consultation with left hemiparesis. A skull computed tomography showed a chronic subdural hematoma and a right parasagittal meningioma. He underwent a two-steps surgery. His post-surgery evolution ran without complications (AU).

ABSTRACT

Inflammatory Myofibroblastic Tumor (IMT) is a rare pathologic entity that was first described in 1973. This lesion is most commonly found in the lungs, but other organs' involvement has also been reported. Intracranial location of Inflammatory Myofibroblastic Tumor is rare, and the first case was reported in 1980. An intriguing fact about the intracranial IMT is its resemblance with meningioma on clinical presentation and neuroimaging. We came across a case of intracranial Inflammatory Myofibroblastic Tumor (IIMT) in a 27-year-old male who presented with recurrent episodes of seizures and was diagnosed as meningioma on neuroimaging. The lesion did not subside with medical management and kept on progressing in size. The patient had to undergo surgery, and diagnosis of Inflammatory Myofibroblastic Tumor was ascertained on histopathology. This 'surprise' diagnosis prompted us to review the literature on all cases of IIMTs reported to date to better understand the entity and its implications. In this review article, we present our observations regarding various studied parameters, including patient profile, clinical presentation, site of involvement, focality of the lesion, special associations, and lines of management of the 49 published cases of IIMTs.

ABSTRACT

RESUMEN Introducción: los meningiomas constituyen la segunda causa de tumores cerebrales primarios, en el adulto. Representan hasta el 32 % del total de los mismos. Objetivo: describir el comportamiento del meningioma intracraneal en los pacientes investigados. Materiales y métodos: se realizó un estudio analítico, descriptivo, retrospectivo a los pacientes neurointervenidos con meningioma intracraneal, en el Servicio de Neurocirugía del Hospital Docente Universitario "Comandante Faustino Pérez Hernández", de la provincia Matanzas. En el período comprendido entre el 1ero de enero de 2017 al 1ero de enero del 2019. Los 15 pacientes intervenidos conformaron el universo de estudio. Resultados: la media poblacional fue de 55 años. Predominó el sexo femenino en un 73,3 %. La cefalea fue la manifestación clínica más frecuente, igualmente, que los meningiomas de la convexidad cerebral. En cuanto a la topografía, la media del tamaño de la lesión fue de 4,4 cm. La variedad meningotelial (40 %) fue la que predominó. El grado II de resección fue el que más se empleó. El edema cerebral postquirúrgico predominó en un 26,6 %. La puntuación de la escala de Karnofsky al egreso fue superior que al ingreso. Conclusiones: cuanto más precoz se realice el diagnóstico clínico y tratamiento quirúrgico en los pacientes portadores de meningioma, mejor será su calidad de vida al egreso (AU).


ABSTRACT Introduction: meningiomas are the second cause of primary brain tumors in adults, representing up to 32 % of the total. Objective: to describe the behavior of intracranial meningioma in the studied patients. Materials and methods: a retrospective, descriptive, analytical study was conducted on neurosurgery patients with intracranial meningioma in the Neurosurgery service of the University Teaching Hospital "Comandante Faustino Pérez Hernández" of the province of Matanzas, in the period from January 1st 2017 to January 1st, 2019. The 15 patients undergoing neurosurgery were the study universe. Results: the population mean was 55 years; female sex prevailed (73.3 %). Headache was the most frequent clinical manifestation as well as meningiomas of cerebral convexity in terms of topography. The average lesion size was 4.4 cm; the meningothelial variety (40 %) was the most commonly found; grade II resection was the most used one. Post-surgical cerebral edema (26.6%) predominated. Karnofsky scale score at discharge was higher than at admission. Conclusions: the earlier the clinical diagnosis and surgical treatment are performed in patients with meningioma the better will be their quality of life at discharge (AU).

ABSTRACT

Los meningiomas de nervio óptico y de seno cavernoso son patologías poco frecuentes, y hasta el momento no ha habido ningún reporte de que se presenten ambos en un mismo paciente. Cabe resaltar que cuando llega un paciente a consulta diagnosticado con alguna patología, asumimos que este diagnóstico es adecuado y pertinente. Pero en nuestro caso, el paciente presentó signos y síntomas de etiología desconocida que hicieron que se re-evaluarán los diagnósticos oftalmológicos que traía la paciente, encontrando que había sido tratada por un diagnóstico que no le correspondía y a su vez este hallazgo nos ayudó a encontrar la verdadera causa(AU)


Optic nerve and cavernous sinus meningiomas are uncommon pathologies, and so far there have not been previously reported to occur in the same patient. It should be emphasized that when a patient arrives at a doctor's office diagnosed with pathology, we assume that this diagnosis is appropriate and pertinent. But in our case, the patient presented signs and symptoms of unknown etiology that led to a re-evaluation of the previous ophthalmological diagnoses that the patient brought, finding that she had been treated for a diagnosis that did not match with all her clinical sign and symptoms and this helped us to find the real cause(AU)

ABSTRACT

RESUMEN Se presentó un caso de una paciente de 70 años de edad, con antecedentes patológicos personales de hipertensión arterial controlada, además de un síndrome demencial instaurado hace 5 años aproximadamente. Con un diagnóstico presuntivo de una demencia tipo Alzheimer y sin estudios desde el punto de vista imagenológico. Se le realizaron diversos estudios que arrojaron una lesión extraaxial interpretada como un meningioma del tercio medio del ala del esfenoides. Se le aplicó una resección tumoral de la totalidad de la lesión, su evolución postquirúrgica fue satisfactoria.


ABSTRACT The case presented is the one of a female patient aged 70 years, with personal pathological antecedents of controlled arterial hypertension besides dementia syndrome for around five years, presumptively diagnosed as Alzheimer-kind dementia without imaging studies. She underwent several studies showing an extra axial lesion that was interpreted as meningioma of the medial third of the sphenoid wing. The tumor resection of the entire lesion was carried out; the post-surgery evaluation was satisfactory.

ABSTRACT

Vinte e dois casos de meningiomas em cães, diagnosticados num período de aproximadamente 18 anos, foram revisados. Os neoplasmas foram graduados e classificados histologicamente de acordo com os critérios da Organização Mundial da Saúde (OMS de 2007) para meningiomas em humanos adaptados para cães, em Grau I (G-I; benignos), Grau II (G-II; atípicos) e Grau III (G-III; anaplásico ou maligno). Dos protocolos de necropsias foram retiradas adicionalmente informações referentes ao sexo, idade, raça, evolução clínica, sinais clínicos, localização anatômica e achados macroscópicos. Os meningiomas intracranianos supratentoriais foram os mais frequentes em relação às demais localizações intracranianas ou intraespinhais. Os intracranianos caracterizaram-se principalmente por sinais clínicos de alteração tálamo-cortical. Os intraespinhais caracterizaram-se principalmente por causarem ataxia. Meningiomas G-I foram os mais frequentes (63,6%) nos 22 cães, seguidos pelos G-III (22,7%) e G-II (13,6%). Os G-I caracterizaram-se por ter o subtipo psammomatoso como o mais frequente, mais de um padrão morfológico em um mesmo tumor, e um terço deles apresentando áreas de invasão do tecido nervoso, 71,4% dos casos acometendo fêmeas, uma média de idade de 11 anos, cães com raça definida como os mais acometidos e por ter o maior tempo de sobrevivência após a manifestação dos sinais clínicos. Os meningiomas G-II caracterizaram-se por ter o subtipo cordoide como o mais frequente, invasão do tecido nervoso em um terço dos casos, somente fêmeas acometidas, uma média de idade de 12 anos, dois terços dos cães acometidos sem raça definida e o tempo máximo de sobrevivência de 20 dias. Os meningiomas G-III caracterizaram-se por ter o subtipo papilar como o mais frequente, invasão do tecido nervoso em 80% dos casos, 60% dos casos acometendo fêmeas, uma média de idade de 8 anos, 80% dos cães acometidos da raça Boxer e o tempo máximo de sobrevivência de 90 dias. Este estudo permitiu estabelecer uma relação entre os três graus histológicos observados em 22 casos de meningiomas em cães com vários parâmetros clínico-epidemiológicos e patológicos, fornecendo informações úteis para um melhor conhecimento da correlação entre a graduação histológica e a evolução clínica desses neoplasmas.(AU)


Twenty two cases of meningiomas in dogs, diagnosed in about 18 years, were analyzed. The neoplasms were histologicaly classified and graded according to the World and Health Organization (WHO of 2007) for human meningiomas, adapted for dogs, in Grade I (G-I; benign), Grade II (G-II; atypical), and Grade III (G-III; anaplastic or malignant). Additional data about gender, age, breed, skull conformation, clinical course and signs, anatomic localization, gross and histological findings were obtained from the necropsy reports. Intracranial and supratentorial meningiomas were the most frequent in relation to the other intracranial or intraspinal sites. The intracranial ones were characterized mainly by clinical signs of thalamic-cortical alteration. Intraspinal ones were mainly characterized by ataxia. G-I meningiomas were the most frequent (63.6%) in dogs, followed by G-III (22.7%) and G-II (13.6%). GI were characterized by having the psammomatous subtype as the most frequent, more than one morphological pattern in the same tumor, one third presenting areas of invasion of nervous tissue, 71.4% of cases involving females, a mean age of 11 years, pure breed dogs as the most affected ones and for having the longest survival time after the manifestation of clinical signs. G-II meningiomas were characterized by having the chordoid subtype as the most frequent, invasion of nervous tissue in one third of cases, only females affected, a mean age of 12 years, two-thirds of the dogs affected were mongrels and the maximum survival time of 20 days. The G-III meningiomas were characterized by having the papillary subtype as the most frequent, invasion of the nervous tissue in 80% of the cases, 60% of the cases involving females, a mean age of 8 years, 80% of dogs affected were Boxers and the maximum survival time of 90 days. In conclusion, this study allowed to establish a relationship between the three histological grades observed in 22 cases of meningiomas in dogs with various clinical-epidemiological and pathological parameters, providing useful information for a better understanding of the correlation between the histological grading and the clinical evolution of these neoplasms.(AU)

ABSTRACT

Los meningiomas son los tumores no gliales más comunes del sistema nervioso central constituyendo el 24%-30% de los tumores intracraneales y el 25% de los tumores de médula espinal. Se originan de células de la aracnoides y en general presentan un comportamiento benigno. Existe un subtipo llamado meningioma extracraneal primario o extradural que es poco frecuente y afecta principalmente el área de cabeza y cuello. Debido a su baja prevalencia y síntomas poco característicos son a menudo diagnosticados por fortuna, siendo la inmunohistoquímica fundamental. Se presenta el caso de una mujer adulta con una lesión tumoral en oído medio diagnosticada inicialmente mediante una biopsia incisional como un granuloma de colesterol. Luego del tratamiento quirúrgico y estudio de inmunohistoquímica se concluye el diagnóstico definitivo de meningioma extradural de oído medio. Se analiza la literatura al respecto y se discute sobre su epidemiología, clínica, estudio y manejo.


Meningiomas are the most common non-glial tumors of the central nervous system constituting 24-30% of intracranial tumors and 25% of spinal cord tumors. They originate from arachnoid cells and generally exhibit benign behavior. The subtype primary extracranial meningioma or extradural meningioma that is uncommon and affects the head and neck area. Due to their low prevalence and uncharacteristic symptoms are often diagnosed by fortune, being the immunohistochemistry fundamental. We present the case of an adult woman with a tumor lesion in the middle ear initially diagnosed by an incisional biopsy such as a cholesterol granuloma. After the surgical treatment and immunohistochemical study, the definitive diagnosis of extradural meningioma of the middle ear is concluded. The literature on this subject is analyzed and its epidemiology, clinical practice, study and management are discussed.

ABSTRACT

Introducción: Los meningiomas de la vaina del nervio óptico (MVNO) son tumores inusuales de la vía visual anterior. Sin tratamiento, el crecimiento del tumor lleva a pérdida visual progresiva hasta la ceguera debido a la compresión que ejerce sobre el nervio óptico. Presentación del caso: Paciente, sexo femenino, 42 años, sin antecedentes mórbidos, que en 1992, inicia cuadro de disminución de la agudeza visual del ojo izquierdo. La resonancia magnética (RM) cerebral informa una lesión expansiva fusiforme en relación a la vaina del nervio óptico izquierdo que lo engloba, altamente sugerente de MVNO. En esa ocasión se realiza exploración de órbita la cual resulta frustra, por lo que se decide observación con controles clínicos e imagenológicos anuales, permaneciendo estable. Aproximadamente diez años más tarde, en el lapso de un año, inicia agravación progresiva de la agudeza y campo visual, ptosis palpebral y alteraciones de la oculo-motilidad del ojo izquierdo, objetivadas por examen neuro-oftalmológico, por lo que se sospecha progresión de MVNO. Se solicita nueva RM que confirma crecimiento significativo del tumor. Se descarta nuevo abordaje quirúrgico por riesgo de mayor deterioro visual y se efectúa radioterapia conformacional con una dosis de 54 Gy. Actualmente, a la edad de 65 años, se cumplen 24 años de evolución, 13 post radioterapia, confirmándose estabilidad clínica y radiológica de MVNO. Discusión: La radioterapia, cuando se observa progresión de la enfermedad, ha demostrado ser una terapia eficaz para los MVNO, con menos complicaciones y con mejores resultados en la preservación de la función visual a largo plazo.


Introduction: Optic nerve sheath meningiomas (ONSM) are rare tumors of the anterior visual pathway. Without treatment, tumor growth leads to progressive loss of visual acuity and blindness due to optic nerve compression. Case report: Patient, female, 42 years without other morbility , begins in 1992 with decreased visual acuity of the left eye, magnetic resonance imaging (MRI) showed enlargement of the left optic nerve sheath, suggestive of ONSM. On that occasion, orbit exploration failed, so it was decided to follow up with annual clinical and imaging controls. About ten years later, begins with progressive deterioration of visual acuity and visual field , with ptosis and ocular motor palsy of the left eye, confirmed with neuro-ophtalmological examinations. MRI shows tumor progression. A new surgical approach was discarded by the risk of visual worsening. A conformal radiotherapy was performed with a fractionated 54 Gy dose. Today, at age 65, after 24 years of follow up,13 post radiation therapy. clinical and radiological stability of ONSM is confirmed. Discussion: Conformal radiotherapy has been shown as an effective therapy, with fewer complications and better outcomes in the preservation of visual function in the long term follow up.

ABSTRACT

As neoplasias no sistema nervoso central (SNC) de animais de companhia são frequentemente diagnosticadas, no entanto dados sobre prevalência são escassos. O objetivo deste estudo foi avaliar retrospectivamente a ocorrência de neoplasias primárias de SNC em cães atendidos em um Hospital-Escola Veterinário e descrever aspectos clínicos, histopatológicos e imuno-histoquímicos dos tumores mais frequentes. Quatorze casos (prevalência de 0,27%) de neoplasias primárias de SNC foram identificados no período de 1998 a 2013 e destes, 11 tiveram o diagnóstico de meningiomas. A idade média dos animais com meningioma foi 10 anos, sendo machos (7/11) e a raça Boxer (3/11) os mais afetados. Sete meningiomas eram espinhais e quatro intracranianos, sendo os principais sinais clínicos alteração na locomoção e convulsões, respectivamente. Metástase pulmonar ocorreu em dois casos. Em seis animais com meningioma espinhal foi realizada a mielografia, sendo que em um também foi realizada a tomografia. Em todos os casos os exames foram efetivos na visualização de desvio ou interrupção da coluna de contraste, com alterações sugestivas da presença de massa. Em cinco animais realizou-se cirurgia exploratória visando a confirmação da suspeita clínica ou retirada da massa, sendo que a sobrevida variou de 85 a 960 dias. Na avaliação histopatológica, os meningiomas foram classificados em transicional (4/11), meningotelial (2/11), papilar (2/11), angiomatoso (1/11), microcístico (1/11) e anaplásico (1/11). Destes, oito (8/11) apresentaram marcação positiva para tricrômio de Masson e um para vermelho congo nas técnicas histoquímicas. No painel imuno-histoquímico, todos os casos apresentaram imunomarcação positiva para vimentina, mas imunomarcação negativa para fator VIII e p53. A imunomarcação para S100 (6/11), GFAP (5/11) e pancitoqueratina (3/11) foi de intensidade variável. Na graduação histológica, dez meningiomas eram grau I e um grau III. O índice médio de proliferação...


Neoplasias of the central nervous system (CNS) of small animals are frequently diagnosed; however, data relative to prevalence are scarce. The aim of this study was to evaluate retrospectively the occurrence of primary CNS tumors in dogs in a Veterinary Teaching Hospital and describe clinical, histopathological and immunohistochemical aspects of the most common tumors. Fourteen cases of CNS primary neoplasia (prevalence of 0.27%) were identified from 1998 to 2013; from these 11 were diagnosed as meningiomas. The mean age of dogs with meningiomas was 10 years; male (7/11) and the Boxer breed (3/11) were most commonly represented. Seven meningiomas were located in the spinal cord and four intracranially; the main clinical signs were impaired locomotion and seizures, respectively. Pulmonary metastasis was found in two cases. Myelography was performed in six dogs with spinal meningiomas. In these cases it was effective in demonstrating the deviation or interruption of the contrast column. Exploratory surgery to confirm diagnosis or remove the tumor was performed in five animals and the survival rate varies 85 to 960 days. Meningiomas were histologically classified as transitional (4/11), meningothelial (2/11), papillary (2/11), angiomatous (1/11), microcystic (1/11) and anaplastic (1/11). Evaluation of histological grade was performed; 10 meningiomas were classified as grade I and one as grade III. The neoplastic cells of eight tumors (8/11) were positive for Masson's trichrome and one with the Congo red histochemical techniques. The immunohistochemical assays revealed in all tumors a positive immunoreactivity for vimentin but negative staining for factor VIII and p53. Immunolabelling for S100 (6/11), GFAP (5/11) and pancytokeratin (3/11) showed a variable staining intensity. The mean cell proliferation index was 3.2 mitotic figures and 3.4% for Ki-67 immunostaining. The results confirmed that meningiomas are the most frequent primary CNS neoplasia...

ABSTRACT

Most intrasellar meningiomas are located in the subdiaphragmatic and supraglandular region because they originate from the diaphragma sellae. Subglandular meningiomas located under the pituitary gland are extremely rare. Intrasellar meningiomas in the subdiaphragmatic and subglandular region probably originate from the dura in the sellar floor. We report a case of a subglandular meningioma along with a review of the literature.

ABSTRACT

Los meningiomas clinoideos son tumores benignos originados en la leptomeninges que rodea el proceso clinoideo anterior, representando el 17 por ciento de los basales. Con el objetivo de caracterizarlos se estudiaron los pacientes operados en el Servicio de Neurocirugía del Hospital Hermanos Ameijeiras (2000 al 2010). La serie estuvo integrada por 10 pacientes, 9 mujeres y un hombre, la edad promedio fue de 49,8 años, clínicamente caracterizados por cefalea (10 pacientes) y déficit de la agudeza visual (9 pacientes). A todos se les practicó un abordaje frontotemporal-orbitozigomático (FTOZ) alcanzándose 7 resecciones totales y 3 subtotales, 3 pacientes sufrieron complicaciones, al alta ocho de los diez operados egresaron en excelente estado, no tuvimos recidiva ni recrecimiento tumoral en los casos con resecciones parciales y al año de seguimiento la calidad de vida según la escala de Karnofsky fue superior o igual a 80 puntos en todos los casos. Concluimos que los meningiomas clinoideos por su asiento en el centro de la base craneal relacionados anatómicamente con estructuras neurovasculares críticas y por las grandes dimensiones que alcanzan en el momento de su diagnóstico, representan un desafío en la práctica neuroquirúrgica, comportándose en nuestra serie más frecuentes entre las mujeres con la cefalea y el déficit visual monocular como síntomas principales. Las técnicas de base de cráneo y en nuestras manos la craneotomía FTOZ complementadas con osteotomías basales de diferentes grados, han demostrado ser una alternativa eficaz para mejorar la suficiencia de la resección tumoral con mínima morbilidad, ausencia de recurrencias y mortalidad.


Clinoidal meningeomas are benign tumors originated in the liptomeningeo surrounding the anterior clinoidal process representing 17 percent of basal tumors. With the objective to characterize it, studied were patients operated in the neurosurgical service of Hermanos Ameijeiras hospital from 2000 to 2010.The series were composed of 10 patients, 9 female and a male, the mean age was 49.8 years and were clinically characterized with headache (10 patients) and visual deficit (9 patients). To all were practiced a frontotemporal orbitozygomatic approach (FTOZ) reaching 7 total and 3 subtotal removal,3 patients suffered complications, 8 out of 10 patients operated were discharged in good condition. There was no recurrence after total removal and after a year of fellow up, the life quality following Karnofsky scale was superior o equal to 80 points in all the cases. In conclusion Clinoidal meningeomas due to its placement in the cranial base with anatomical relations with critical neurovascular structures and also the great dimension to reach in the moment of its diagnosis represents a challenge to neurosurgical practice. It comports in our series with more frequency within females presenting headache and mono ocular visual defect as the principal symptoms. Craneal base techniques and in our case frontotemporal-orbitozygomatic craniotomy complimented with basal osteotomy of different grades, had demonstrated to be an efficient alternative to better the technique of total removal with less mobility, zero recurrence and mortality.

ABSTRACT

The spontaneous intracranial hemorrhage associated with cerebral tumors constitutes a rare event. The isolated spontaneous subdural hematoma related to a cerebral tumor represents an even more striking condition. Some hypotheses have been formulated to attempt to explain the occurrence of the spontaneous hemorrhages associated with intracranial meningiomas, but there is no consensus on its formation. We report on a case of a male patient presenting intense headache, without traumatic brain injury history, in which investigation showed an intracranial meningioma associated to a spontaneous subdural hematoma. He was submitted to a cranial surgery, presenting good recovery. We also perform a brief review on the theme.


La hemorragia intracraneal espontánea asociado con tumores cerebrales constituye un evento raro. El hematoma subdural espontáneo aislado relacionada con un tumor cerebral representa una condición aún más sorprendente. Algunas hipótesis han sido formuladas para intentar explicar la aparición de las hemorragias espontáneas asociadas con meningiomas intracraneales, pero no hay consenso sobre su formación. Se presenta un caso de un paciente de sexo masculino que presentó dolor de cabeza intenso, sin historia de lesión cerebral traumática, en el que la investigación mostró un meningioma intracraneal asociado a un hematoma subdural espontáneo. Se le sometió a una neurocirugía, presentando una buena recuperación. También realizamos una breve revisión sobre el tema.
