The low intracranial pressure syndrome.

Abstract

The syndrome of low intracranial pressure may develop in a variety of circumstances, e.g. after lumbar puncture, following head injury and intracranial operations. It sometimes occurs after viral meningitis. The case history is described of a woman in whom the disorder was unusually severe and persistent. Interesting radiological features were observed, the appearances being those of herniation of the brain towards the tentorial opening. Simple measures of treatment produced dramatic and lasting relief.
