A Case Report: Intracranial Hypotension with Dizziness and Tinnitus

Abstract

Intracranial hypotension, caused by lumbar puncture, spinal anesthesia, arachnoidal cyst, and arterio venous malformation, has become increasing common. Symptoms vary including vertigo, tinnitus, hearing loss, headache, photophobia, and nausea. These are relieved upon reclining and are worsened by sitting or standings. We treated a patient in whom dizziness and tinnitus were evoked after anesthesia, and downbeating vertical nystagmus, was recorded by infra-red CCD camera. Our findings suggested this patients nystagmus was caused by downward displacement of the cerebellum due to intracranial hypotension.
