[Intracranial meningiomas. The Dakar experience apropos of 79 cases]

We report our experience with 79 intracranial meningiomas operated on between 1960 and 1995 in Dakar Senegal. In our geographical region issues concerning diagnosis, therapy and clinical course are still a topic of debate due mainly to the lack of high-performance technical units. All patients were admitted with evident symptoms. The classically described prevalence was not found in this series. Thirty-one cases presented intracranial hypertension with or without a focal syndrome which evidenced a motor deficit in 32 cases and irritative lesions in 24. External bulging of the meningioma was observed in a large number of cases (11.4%). Until 1994, angiography was the only available means of diagnosis. Mortality was high (30 cases) and results depended on delay to surgery, tumor localization and operative conditions. Our results have been improving over the years but cannot be sustained unless the technical unit is upgraded.
