ABSTRACT

RATIONALE: Hydatid cyst is a disease caused by the larvae of Echinococcus spp. The larvae often reside in the liver, lungs, and brain. Occasionally, a primary isolated thoracic vertebral hydatid cyst is reported to cause severe complications. Various diseases may lead to the development of progressive compressive myelopathy. Herein, we report a rare case of a primary isolated thoracic vertebral hydatid cyst with compressive myelopathy. PATIENT CONCERNS: A 57-year-old female had numbness and weakness in the lower limbs for a span of 3-months. DIAGNOSIS: Thoracic magnetic resonance imaging (MRI) showed that an isolated mass was observed in the T5 vertebral body, which compressed the spinal cord. The diagnosis was confirmed after surgical excision, and Echinococcus granulosus was found to be the etiologic factor. INTERVENTIONS: The patient underwent laminectomy with no complications. OUTCOMES: After surgical decompression, the patient made slow and measurable progress. While relatively rare in the non-pastoral area, the primary isolated thoracic vertebral column hydatid cyst may be considered as a possible etiology of atypical extradural spinal compression. LESSONS: This case illustrates the complexity of spinal echinococcosis manifestations and the necessity of an interdisciplinary approach.

ABSTRACT

Aberrant Dirofilaria immitis migrans is a rare cause of neurologic signs in dogs, however, published studies describing the computed tomographic (CT) and magnetic resonance imaging (MRI) characteristics of this problem are currently lacking. The objective of this retrospective case series study was to describe the clinical and imaging findings for four adult dogs with verminous myelopathy due to aberrant Dirofilaria immitis migrans within the cervical subarachnoid space. All dogs were toy breeds, were heartworm antigen positive, had neurologic signs (ranging from cervical hyperesthesia to tetraparesis), and similar MRI findings. In two patients additionally imaged with CT, findings were variable. On MRI, each dog had a single large, dorsal- to laterally located, intradural-extramedullary, fusiform mass with characteristic stippled, mixed T2-weighted and T1-weighted signal intensity, hypo-to-iso T1-weighted signal intensity, and spinal cord compression. Nematodes were identified as serpentine or circular subarachnoid structures with low T2-weighted and T1-weighted signal in the sagittal and transverse image planes, respectively. CT (n = 2 dogs) demonstrated focal regions of mildly enhancing intradural-extramedullary spinal cord compression in 1 dog. Dorsal laminectomy and durotomy were performed in two dogs at C3-C4. A C4-5 hemilaminectomy with durotomy and dural biopsy was performed in one dog. Extraction of live, immature adult, female D. immitis worms was performed in three dogs. Operated dogs had complete post-surgical resolution of clinical signs. One dog was euthanized without surgery; necropsy revealed an adult heartworm in the spinal subarachnoid space at C2. Findings indicated that cervical spinal subarachnoid D. immitis aberrant migration should be considered as a differential diagnosis for dogs with this combination of clinical and CT/MRI imaging findings, and that the prognosis may be good with early detection and surgical removal.

ABSTRACT

INTRODUCTION: This case report describes a 13-year-old cob-cross gelding presented for evaluation of recent onset hindlimb ataxia. The gelding had undergone general anaesthesia and tenoscopy of the right hindlimb digital flexor tendon sheath at a nearby clinic three months earlier and had appeared normal at routine post-operative assessments until the sudden onset of neurological deficits. Spinal trauma was suspected initially but radiography and scintigraphy were unremarkable. Due to the severity and progressive nature of the clinical signs the -gelding was subjected to euthanasia. Post mortem examinations (computed tomography, dissection and histopathology) revealed spinal cord compression caused by a single extradural hydatid cyst (Echinococcus equinus), confirmed with PCR, at the level of the 15th thoracic vertebra. This is the first report of a spinal hydatid cyst causing hindlimb ataxia and should therefore be considered a potential differential diagnosis for ataxia in the equine patient.


INTRODUCTION: Ce rapport décrit le cas d'un hongre croisé cob de 13 ans présenté pour l'évaluation d'une ataxie des membres postérieurs d'apparition récente. Le hongre avait subi une anesthésie générale et une ténoscopie de la gaine du tendon du fléchisseur digital du membre postérieur droit dans une clinique voisine trois mois auparavant et avait semblé normal lors des évaluations postopératoires de routine jusqu'à l'apparition soudaine de déficits neurologiques. Un traumatisme rachidien était suspecté au départ, mais la radiographie et la scintigraphie étaient sans particularité. En raison de la gravité et de la nature progressive des signes cliniques, le hongre a été euthanasié. Les examens post mortem (tomodensitométrie, dissection et histopathologie) ont révélé une compression de la moelle épinière provoquée par un unique kyste hydatique extradural (Echinococcus equinus), confirmé par PCR, au niveau de la 15e vertèbre thoracique. Il s'agit du premier cas rapporté d'un kyste hydatique au niveau de la colonne vertébrale causant une ataxie des membres postérieurs et doit donc être considéré comme un diagnostic différentiel potentiel de l'ataxie chez le patient équin.

ABSTRACT

Guillain Barre Syndrome (GBS) is a challenging pathology which diagnosis is based essentially on the clinical examination and the results of lumbar puncture. Differential diagnosis must be discussed if the clinical picture is not complete. We present the case of a patient who presented to the emergency department with symptoms evoking both GBS and spinal cord compression. The Radiology showed a diffused spinal hydatidosis. The lumbar puncture must be carefully considered. In this case, it would have exposed the patient to hydatid dissemination.

ABSTRACT

Common bony spinal pathologies that could present with progressive spasticity include vertebral body tumors or chronic infections of the spine. Cysticercosis of the spine commonly has an intramedullary occurrence. The authors discuss the presentation and management of a rare case of solitary vertebral cysticercosis that presented with lower-limb spasticity and sphincter involvement.

ABSTRACT

Intradural extramedullary type of spinal hydatid disease is a rare variety of hydatid disease, and is even rarer in paediatric age group. Spinal hydatid disease should be considered in the differential diagnosis of spinal cord compression syndrome in endemic countries and should be evaluated with imaging and serological investigations. Our case was a 9- year-old boy who presented with lower back pain lasting for 8 months and progressive bilateral lower extremities weakness lasting for 2 month. Neurological examination was suggestive of lower motor neuron type of paraperesis. Magnetic resonance images of the lumbar spine showed an intradural cystic lesion displacing and compressing the lower cord and cauda equina. The cystic mass was explored with L1-L4 laminectomy and after durotomy; it was separated from cord and dura mater by hydrodissection. It contained a clear fluid. The pathological diagnosis was hydatid disease.

ABSTRACT

Schistosomiasis of the spinal cord is an uncommon but potentially curable form of schistosomiasis, if diagnosed and managed early. The spinal cord is more frequently affected in Schistosoma mansoni or S. haematobium infections. This paper describes the clinical manifestations, diagnosis and management of schistosomiasis of the spinal cord in 5 patients attending Shaab and Ibn Khuldoun Hospitals, Khartoum from 1997 to 2007. There were 4 males and 1 female aged 9-45 years. They presented with symptoms and signs due to cord compression at the lower thoracic and lumbar vertebrae. Imaging studies revealed intramedullary masses compressing the cord. Biopsy showed ova of S. mansoni with surrounding inflammatory reaction. The cord showed demyelination near the ova and an associated inflammatory reaction. Patients responded well to surgical ecompression and treatment with praziquantel and oral steroids.

ABSTRACT

The involvement of spinal column in cyst hydatid disease is rare and hard to treat. The gold standard treatment is total removal of the cysts without rupture. However, recurrence after surgery is almost inevitable and reoperations carries technical difficulties and higher morbidity. We present a 69-year-old woman with two cystic masses at the T12 level, which compress the spinal cord causing severe paresis in her left leg. Under local anestesia, the cysts were aspirated and irrigated with 20% hypertonic saline solution via bilateral T12 transpedicular route. We aimed to report that percutaneous CT guided treatment should be considered as an alternative therapeutic option in case of recurrent spinal cyst hydatid.

ABSTRACT

Neuroschistosomiasis caused by Schistosoma mansoni (Sm) is a rare and severe condition potentially leading to permanent neurological deficit. An 18-year-old Brazilian female was admitted due to a severe conus medullaris and cauda equina syndrome. MRI of thoracic/lumbar spine showed an expanded conus medullaris with patchy gadolinium-enhancement, needle electromyography revealed acute bilateral radiculopathy (L5-S1-S2), cerebrospinal fluid (CSF) showed lymphocytosis and increased proteins and lesion' surgical biopsy documented a lymphocyte infiltrate. Immunodiagnosis with cercariae hullen reaction using Sm cercariae in CSF and serum and immunoelectrodiffusion for circulating antigens detection using anti-Sm antibodies were positive. No schistosoma parasites were found. The patient was treated with praziquantel and corticotherapy for 6 months. At 1 month, partial clinical improvement was noticed, and MRI showed a normal size conus medullaris. At 6 months, there was complete clinical recovery. This case shows that a severe neurological deficit by Sm may have a clinical full recovery after treatment.

ABSTRACT

OBJECTIVE: Spinal hydatid cyst is a serious form of hydatid disease affecting fewer than 1% of all patients with hydatid disease. We report 3 healthy patients who presented with progressive paraparesis attributed to a histologically proven intradural hydatid cyst. METHODS: There were 2 children (1 boy, 1 girl) and 1 adult with a mean age of 12 years. The median follow-up duration was 16 months. Spinal magnetic resonance imaging was performed in the 3 patients, and an anatomic and topographical diagnosis of the intradural hydatid cyst was made. RESULTS: Magnetic resonance imaging scans revealed cystic lesions with peripheral contrast enhancement. Surgery was performed through laminectomy, complete resection was achieved, and antihelminthic treatment with albendazole 10 mg/kg-1 per day for 6 months was included in the postoperative treatment. The patients improved after surgery with normal motor function. CONCLUSION: This localization is rare and serious, but its prognosis is excellent if diagnosis is made early enough and surgery is performed in time to prevent cyst rupture.

ABSTRACT

Osseous hydatidosis, especially when located in the rib, is a very rare disease. Less than 50 cases of costal echinococcosis have been reported in the literature to date. The authors report a case of echinococcosis of the rib with epidural extension in a 76-year-old patient presenting paraparesis. In addition, the patient presented a large posterior and thoracic soft tissue mass measuring about 30 centimetres in diameter. A chest x-ray, a CT thoracic scan and an MRI of the dorsal spine were performed. The imaging suggested echinococcosis of the rib with epidural extension. The cyst was completely resected. Histopathology of the resected specimen confirmed the diagnosis of echinococcosis. The patient died due to postoperative complications. Accurate presurgical diagnosis allows for appropriate management and helps eradicate the disease. This also prevents the dissemination of parasites and further complications.

ABSTRACT

Primary spinal hydatid disease is rare. Spinal hydatid disease should be considered in the differential diagnosis of spinal cord compression syndrome in endemic countries and evaluated with imaging and serology. Our case was a 34- year-old man. The patient presented with progressive back pain for 8 months and lower extremity weakness for 3 months. Neurological examination was suggestive of upper motor neuron type of paraperesis. Magnetic resonance images of the thoracal region showed an intradural multicystic lesion. The mass was explored with T 10-11 laminectomy. It had displaced the cord to the right side. The fluid was clear and did not contain pus. The lesion was easily dissected from the cord and was resected totally. The pathological diagnosis was hydatid disease.

ABSTRACT

OBJECT: The authors performed a study to investigate the clinical manifestations, treatment strategies, and possible pathogenesis of conus medullaris schistosomiasis. METHODS: Six cases collected from the authors' experience and four cases reported in the literature were studied retrospectively for clinical manifestations, treatment outcomes, and prognosis. All patients experienced progressive lower-extremity weakness and functional bowel and bladder impairment. Although the magnetic resonance (MR) imaging results suggested the presence of a conus medullaris tumor, schistosomiasis was diagnosed based on pathological results obtained in the 10 patients. The results of surgery followed by pyquiton and hormone treatment confirmed the diagnosis, and the patients' prognoses were good. CONCLUSIONS: This pathological entity is predominantly found in adults, and the clinical manifestations have no specificity, although the MR imaging may provide some clues. As a form of ectopic schistosomiasis, conus medullaris schistosomiasis deserves special consideration and further exploration. If an early diagnosis can be made and pyquiton and hormone therapy is given, surgery can be avoided and the prognosis will remain good.

ABSTRACT

A novel case where onchocercosis was identified as a cause of cervical myelopathy in the horse is described. A 15-year-old Connemara mare was euthanized due to progressive locomotion disturbance. Postmortem examination revealed soft-tissue swelling in the intervertebral joint capsule of C6-7 with narrowing of the vertebral canal. On light microscopy, axonopathy was pronounced in the corresponding segment of the spinal cord. Fibrous tissue and eosinophilic granulomas were found in the joint capsule, together with parasites identified histologically as Onchocerca sp.

ABSTRACT

Spinal hydatid cysts account for 1% of all cases of hydatid disease; primary intradural hydatid cysts are uncommon. We present a case of pathologically confirmed intradural spinal cyst hydatid in an otherwise healthy patient who showed no other evidence of systemic hydatid cyst disease. The patient presented with back pain, paraparesis, and weakness. An intradural extramedullary cystic lesion was identified with magnetic resonance imaging and was shown to be a hydatid cyst by histopathologic examination after surgical removal. To our knowledge, this is the 25th case of hydatid cyst at an intradural extramedullary location reported in the literature.

ABSTRACT

Neurocysticercosis is the most common parasitic infestation involving the central nervous system in tropical countries. Common presentations are seizure, meningitis and increased intracranial pressure. The authors report a case of a 52-year-old woman with racemose neurocysticercosis in the subarachnoid space at the cistern of the brain through the lumbar cistern. She presented with progressive paraparesis due to spinal cord compression and finally had progressive bilateral sensori-neural hearing loss. MRI brain and the whole spinal cord revealed numerous rim-enhancing cystic lesions at the basal cistern, prepontine cistern, bilateral cerebellopontine angle, internal acoustic canals, intramedullary lesion at the 5th cervical spinal level, lumbar cistern lesions and secondary syringomyelia at the thoracic spinal cord. The histopathologic examination confirmed cysticercosis. After treatment by albendazole and surgical removal, she still developed recurrent spinal compression at a higher level and obstructive hydrocephalus. Finally, she died from status epilepticus and septic shock.

ABSTRACT

The authors report a case of cauda equina compression by intradural hydatid cyst. An 18-year-old man presented with paraparesis and sphincter dysfunction. MRI showed an intradural cystic lesion extending from L1 to L2 with low signal intensity on T1 and high signal intensity on T2. The cyst was removed after laminectomy and opening of the dural sac. Histological and parasitic examinations confirmed a diagnosis of hydatid cyst. The patient improved progressively after surgery. The similar 22 cases of intradural extramedullary hydatid disease reported in the literature were reviewed. All spinal areas were involved, with a predilection for the thoracic region. Neurological complications were usual with rapid spinal cord compression in this rare form of hydatid disease. The treatment was by surgery with a favourable outcome compared to the classic hydatid cyst of the spine.
