Pathological lesions include neurilemmomas arising from the neural sheath and neurofibromas that are centrally placed, with nerve fibers traversing the tumour mass. Nerve tumours that are intraneural in location but non-neural in origin include fibrofatty infiltrate, intraneural lipomas, hemangiomas and ganglion cysts. The term lipofibromatous hamartoma was introduced by Johnson and Bonfiglio (1) to describe a diffuse lipofibromatous infiltration of a nerve. These may occur as well encapsulated or diffusely infiltrative tumours. The well encapsulated tumours occur most commonly in women in their 40s and 50s. Due to its rare occurrence, the present article describes a case of intraneural lipoma of the ulnar nerve at the elbow that presented as compression neuropathy.
