Postural tremor as a manifestation of spontaneous intracranial hypotension

Abstract

Spontaneous intracranial hypotension (SIH) is a syndrome caused by low cerebrospinal fluid (CSF) pressure due to leakage of CSF. Clinically, orthostatic headache, neck pain, nausea, emesis, interscapular pain, diplopia, dizziness, changes in hearing, visual blurring and radicular upper extremity symptoms are most frequently observed. We describe a 57-year-old man with SIH who presented with postural tremor. CSF leakage was revealed by cranial MRI. Lumbar puncture identified low CSF pressure and intrathecal gadolinium enhanced MR cisternography showed diffuse CSF leakage in the thoracolumbar region. The patient underwent epidural blood patching, which resulted in complete resolution of postural tremor within 2 months. (C) 2009 Elsevier Ltd. All rights reserved.
