“…This lipomatous process also has been designated fibrofatty overgrowth of a nerve, fatty infiltration or fatty enlargement of a nerve, lipofibroma, lipomatous hamartoma, intraneural lipoma, and perineural lipoma (5, 8). Most cases of FLH arise in the median nerve (1–3, 8, 9), although involvement of the ulnar nerve (4, 5, 8), or other peripheral nerves (3, 4, 6, 8) may occur. Fibrolipomatous hamartoma, although uncommon, has become important to recognize because it may cause a mass effect leading to neurologic complications (3, 5, 8), and it often relates to macrodystrophia lipomatosa and macrodactyly (1, 5, 8).…”
