Spontaneous intracranial hypotension from intradural thoracic disc herniation. Case report

Abstract

Spontaneous intracranial hypotension (SIH) may result from occult leaks anywhere along the neuraxis. Although this syndrome has been recognized over the past 10 years in the neurology and radiology literature, the typical magnetic resonance (MR) imaging picture and clinical course are less well known to neurosurgeons. The authors describe the case of a patient with positional headache and MR imaging findings typical of SIH that resulted from an intradural disc herniation.
