Posterıor Interosseous Nerve Syndrome Caused by Intramuscular Lipoma: A Rare Case of Radial Neuropathy

Abstract

Lipomas are common benign soft tissue neoplasms that occur usually in subcutaneous tissue. In rare instances they can occu r in the deep soft tissue such as intramuscular and parosteal sites. When an intramuscular lipoma occurring in the proximal forearm or adjacent to the proximal radius they can compress the posterior interosseous branch of radial nerve and cause paralysis o f posterior interosseous nerve. In this report we describe an unusual case of a 55 - year - old man with posterior interosseous nerve syndrome caused by quite small intramuscular lipoma.
