Detection of CSF leaks with magnetic resonance imaging in intracranial hypotension syndrome.
Overview
abstract
Intracranial hypotension syndrome (IHS) is a rare disorder characterized by postural headache, low cerebrospinal fluid (CSF) pressure, dural thickening and pachymeningeal contrast enhancement as a consequence of decreased CSF volume. The present report is a case of spontaneous IHS due to dural leak at the level of T12-L1. The site of CSF leakage was not detectable on either conventional magnetic resonance imaging (MRI) or T2-weighted MR myelography. However, it was evident on contrast-enhanced MR myelography (CE-MRM). The present report discusses the efficacy of CE-MRM in the detection of CSF leaks according to the literature so far.
