STUDY DESIGN This study analyzed a series of 83 patients operated on for foraminal lumbar disc herniation. OBJECTIVES This study sought to develop clinical and radiologic diagnoses, evaluate interlaminar and extra-articular exposures, and evaluate postoperative results. SUMMARY OF BACKGROUND DATA Some authors have reported a specific clinical syndrome,(More)
Pseudocyst formation is a rare complication of ventriculo-peritoneal shunt, occurring in only 22 cases of 1300 shunts from 1968 to 1992. The most common presentation is that of abdominal signs rather than neurological or infectious signs. The diagnosis is easy with ultrasonography. The difficulty is to evocate the cyst and to correlate symptoms and cyst.(More)
A case of an osteoblastoma located in the odontoid process in a 7 year-old boy who presented with torticollis is reported. CT scan and MRI disclosed the lesion, but diagnosis was established by a CT-guided needle biopsy. Surgery through a transoral approach allowed total excision of the tumor. This is, to our knowledge, the first case reported of an(More)
Intracranial or spinal epidural hematomas are almost always of post-traumatic origin, and rarely related to rupture of a dural vascular malformation or a hemostasis disorder. We report a case of spontaneous cerebral epidural hematoma observed in a young girl with homozygous sickle cell disease. After analysis of post-operative cerebral MRI, showing skull(More)
Ewing's sarcoma (ES) of the skull is rare. Herein, we present 2 cases of ES that involved the cranium in young children. In one case, the lesion originated in the petrous temporal bone; in the other, the frontal bone. Both children were acutely compromised neurologically by signs and symptoms of raised intracranial pressure. In both cases, radiographs(More)
Three groups of patients with single hemispheric brain abscesses or subdural empyemas, from 1 to 5 cm large, with similar initial prognosis, have been treated either by medical treatment alone (20), aspiration (21), or excision (15). Differences in survival were not found, but medical treatment alone was better for long term sequelae. Surgical procedures(More)
A collection of 28 medulloblastomas was analyzed for expression of the developmental control genes PAX-6 and EN by immunohistochemical staining. Sixteen medulloblastomas expressed both EN and PAX-6 but, when differentiation could be assessed in the positive areas, PAX-6 is expressed in the less differentiated cells. Since Drosophila en encodes a negative(More)
Central nervous system infection by the larval form of the pork tapeworm, taenia solium is a major public health problem in view of its prevalence. The high incidence of neurocysticercosis in Reunion Island has been precised by computerized tomography and Elisa test. Spinal involvement is an uncommon form of cysticercosis, occurring with a frequency of less(More)
A 42-year-old man with a history of benign incidental dorsal trauma 5 years earlier presented with progressive weakness of the right leg for 2 years. Clinical examination revealed decreased left-sided pain, temperature, and light touch sensation below the level of T2, right leg weakness, normal proprioception, and increased deep tendon reflexes in the right(More)
Brain abscess following dental or periapical infection is rare in childhood. This report describes brain abscesses found in two children with dental caries. Case 1.--A 12 year-old boy was admitted because he had suffered from acute meningitis for 3 days. Clinical examination showed symptoms of meningitis plus palsy of the right third and fourth cranial(More)
