Sciatic hernia causing sciatica: MRI and MR neurography showing entrapment of sciatic nerve

Chitranjan et al. Br J Radiol. 2010 Mar.

Abstract

Sciatic hernia is a rare condition with diverse clinical manifestations. We report a case of sciatic hernia causing sciatica, in which the diagnosis made on CT was subsequently confirmed on MRI including magnetic resonance neurography. The salient clinical and imaging features and a brief review are presented.
