RESUMO
Meningioma is an uncommon tumor of childhood. In this group, supra tentorial forms predominate. We report the case of a 14 years old boy without any past medical history. He presented headaches, vomiting and cerebellar syndrome. CT scan shows cerebellar tumor, enhanced by contrast and surrounded by edema, looking like tuberculoma. After fail of tuberculosis treatment, the boy is operated by suboccipital approach. Histology and immuno histochemical examination show fibroblastic meningioma. Even if it is rare, meningioma can occur in childhood, without neurofibromatosis disease. It can present many points of likeness with tuberculoma and therefore biopsy is mandatory before tuberculosis drugs giving.

The authors report a retrospective study over two years in order to assess computed tomography (CT) in the diagnosis of intracranial tumors. Results were analysed on the epidemiological, clinical and CT point of view. CT is a sensitive and non invasive exploration which should be performed first when intracranial tumor is suspected. However its cost remain high for most of the patient.

From 1980 to 1990, 64 cases of Lumbar canal Stenosis have been recorded and operated on at the neurosurgical clinic. The male sex is prevailing and the breakdown by age groups showed a preponderance of the age sections between 31 and 45 and 46 and 60 years. The sciatic pain was the most frequent starting symptom. As far as the physical signs are concerned, the areflexy of the tendon predominates. The saccoradiculography has established the diagnosis in most of the cases. The laminectomy associated with another technique has permitted to obtain the best result of the treatment. With the advent of the T scan, a better estimation of the lumbar canal will be possible, so as to replace the laminectomy by a more adaptable technique: the remeasurement of the lumbar canal.

Because of frequency and seriousness of myelo radicular complications of narrow lumbar canal, the authors studied its radiological and anatomical measurements in order to specify the standards for senegalese negro african. For that purpose, they collected samples of 21 lumbosacral spines from new cadavers through medico legal necropsies. Pieces have been first X rayed, then treated. They measured the antero posterior diameter of vertebral corpse, the anterio posterior diameter of vertebral canal, the narrowest transversal diameter of vertebral corpse and the inter pedicular distance. The authors found no significant differences between radiological and anatomical measurements, but the latest changed from one stage to another. The variations also were not important comparatively to standards established by two authors.
