Sciatic Neuropathy From a Giant Hibernoma of the Thigh: A Case Report

Abstract not available. Introduction provided instead.

Hibernomas—rare, uniformly benign soft-tissue tumors of brown fat—were originally described in 1906 by Merkel.¹ These tumors are usually found in the scapular² and posterior cervical regions or (more rarely) in the folds of the buttocks or on the thigh.^3-5 Sciatic neuropathy is an infrequently diagnosed focal mononeuropathy. Few case reports of lipomas compressing the sciatic nerve or its peripheral branches have appeared in the literature.^6-8 The present case report is to our knowledge the first on sciatic nerve palsy caused by a hibernoma.
