A fibrolipomatous hamartoma-also known as a fibrofatty overgrowth, perineural lipoma, intraneural lipoma, and lipomatous hamartoma-is a rare, benign, congenital lesion most commonly found in the median nerve, usually at the level of the wrist or hand. To our knowledge, no published cases report a hamartoma arising from the median nerve at the level of the elbow. We report a case of a fibrolipomatous hamartoma in a 55-year-old woman that necessitated a surgical intervention because of its size and associated neurologic symptoms.
