[Clinical and therapeutic aspects of benign intracranial hypertension].
BACKGROUND
Benign intracranial hypertension (BIH) or pseudotumor cerebri is diagnosed on the basis of Dandy's criteria. BIH creates an emergency situation because of the risk of lost vision. In this work, we studied retrospectively a series of 10 cases of BIH all meeting Dandy's criteria. Our objective was to assess the benefit of the corticosteroid-acetazolamide combination on clinical course, especially on papiledema.


METHODS
Eighty-four patients were hospitalized at the neurology department (Hopital des Specialites, Rabat) over a period of 14 years (1988-2001). They were divided into three groups: forty cases of cerebral thromophlebitis, 10 cases of BIH. In the remaining 34 cases, the investigations were insufficient, so that Dandy's criteria could not be verified. We studied only the 10 cases presenting with a diagnosis of BIH diagnosis complying with Dandy's criteria. The patients underwent a physical examination, cerebral magnetic resonance imaging (MRI) if possible or CT scan with conventional angiography, and CSF examination with pressure measurement. We analyzed age, sex-ratio, clinical aspects and the outcome after treatment. The major criterion of outcome was the regression of papilledema.


RESULTS
There were 9 women and 1 man. The mean age was 24.6 8.4 years. Behcet's disease was noted in 3/10 patients. The clinical features were those described in the literature. Patients were treated by corticosteroids combined with acetazolamide and CSF depletion in all cases. CSF derivation was performed in only 1 patient. Definitive blindness was noted in 2 patients at admission. A favorable course was noted in 8/10 cases, with regression of papilledema within approximately 1 month.


CONCLUSIONS
We suggest that the corticosteroid-acetazolamide combination can have a beneficial effect on papilledema in BIH. However, these results should be confirmed by a prospective, randomized, double blind controlled study.
