Nuchal-type fibroma of the buttock: magnetic resonance imaging findings

Abstract

Nuchal-type fi broma, fi rst described in 1988 by Enzinger and Weiss, is a rare fi brous growth occurring predominantly in the interscapular and paraspinous regions. It is typically located in the subcutaneous tissue of the posterior neck but may occur in extranuchal soft tissue sites such as the upper back, shoulder, and facial regions. In this article, we describe the magnetic resonance imaging fi ndings of a nuchal-type fi broma that involved the buttock in a 45-year-old woman, and we review and discuss the literature on the subject.
