Abstract
SUMMARY: Pseudotumor cerebri is a clinical syndrome in which signs and, sometimes, symptoms of raised intracranial pressure are present hut in which mental and neurological function are unaffected. Therefore, the diagnosis is reached after mass and other structural causes of raised pressure have been excluded. Many causes of pseudotumour have been suggested, not all of them well documented. Pathogenesis, however, includes cerebral edema, increased cerebral blood volume, and decreased cerebro spinal fluid (CSF) absorption. Except for the risk of vision in a minority of cases, the prognosis is excellent.
