[Acute inter-hemispheric subdural hematoma].

Interhemispheric subdural hematoma in adults is a rare complication of head injury with no more than 100 cases reported since 1940. The classical presentation of this disorder is a contralateral monoparesis of the leg or a hemiparesis more pronounced in the leg. We report three cases of interhemispheric subdural hematoma following closed head injuries and the review of the literature with an analysis and of the therapeutic possibilities. Conservative management under close supervision may be a proper attitude in those patients without alterations of consciousness. Surgical treatment is necessary in patients with progressive deterioration.

[Spinal meningiomas].

OBJECTIVE: Meningiomas account for 15 to 45% of spinal cord tumors. They are more frequent in females and have low recurrence rate due both to their low tendency for regrowth and to their prevalence in the aged population. METHODS: We reviewed retrospectively the clinical records of 37 patients operated on for spinal meningioma in our Neurosurgical Service from 1982 to 1998. Duration and type of symptoms, radiological and surgical results are analyzed. RESULTS: Our spinal meningiomas account for about 26% of all spinal cord tumors operated on during a 19-year period. They accounted for 11% of all meningiomas operated during the same period. We observed a higher prevalence in females between 50 to 70 years of age. Weakness and localized pain were the most common presenting symptoms. The tumors were located in the thoracic region in 33 patients and only one case was found to be completely extradural. All the patients were operated on by laminectomy and total removal was achieved in all cases. CONCLUSIONS: The use magnetic resonance to make an early diagnosis and microsurgical techniques appeared as the most relevant factors for further improvement of the surgical results.

[Thalamic abscess. A stereotaxically treatable lesion].

Solitary abscesses of the thalamus are an infrequent entity which carry serious problems with regard to treatment. We present a patient with an unknown septic focci who developed a right thalamic abscess due to Streptococcus constellatus and was treated by stereotaxic drainage for the suppuration and antibiotics. The patient was clinically and radiologically (CAT) controlled up until total cure of the lesion. Complications included dissemination of the infection to the meningeal space and a residual coreic picture controlled with tetrabenzine. The authors believe that evacuation by stereotaxic punction should be included among the therapeutic options available for deeply localized cerebral abscesses.

[Intracranial ependymomas].

INTRODUCTION: Ependymomas are tumours derived from ependymal cells, found lining the cerebral ventricles and central canal of spinal cord. Intracranial ependymomas account for 2 6% of all neoplasms of the central nervous system and at least half present in the first two decades of life. DEVELOPMENT: We review the epidemiological, clinical, neuropathological details, neuroradiological aspects and treatment of intracranial ependymomas. CONCLUSIONS: Ependymomas of the posterior fossa predominate in children, while supratentorial tumours are more common in adults. This analysis of the literature further highlight that total tumour removal is the treatment of choice for intracranial ependymomas. Postoperative survival was predominantly dependent on the histological grade of malignancy, the extension of surgery and the age of the patient.

[Neurofibromatosis and stenosis of the aqueduct of Sylvius. A magnetic resonance assessment].

Von Recklinghausen's neurofibromatosis is an autosomal dominant disease involving peripheral nerves and central nervous system. Obstructive hydrocephalus in this disease represents a common finding when it is due to the development of infratentorial neoplasm. Nevertheless, the occurrence of isolated nonneoplastic aqueductal stenosis in patients affected by neurofibromatosis has been described rarely. The authors report two cases of primary nontumoral aqueductal stenosis associated with Von Recklinghausen's disease who were diagnosed by CT scan and MRI. The pathogenesis of aqueductal narrowing in neurofibromatosis is discussed.

[Meningioma of the third ventricle. Presentation of a case].

Meningiomas of the third ventricle are extremely rare; the authors report a case of meningothelial meningioma located in the anterior part of the third ventricle. The tumor was successfully removed through a trans-ventricular approach. The clinical presentation, radiological findings and surgical management of these tumors are reviewed.
