Nuchal-type fibroma, first described in 1988 by Enzinger and Weiss, is a rare fibrous 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 findings of a nuchal-type fibroma that involved the buttock in a 45-year-old woman, and we review and discuss the literature on the subject.
