An intramuscular lipoma in the medial head of triceps brachii muscle simulating nerve sheath tumour of ulnar nerve: a rare case report

Lipomas are the most frequent benign mesenchymal neoplasms of mature fat cells found commonly on the back and upper extremities usually occupying the subcutaneous plane. Intramuscular lipomas are rare and may mimic malignant lesions. Magnetic resonance imaging can not only identify and localise these tumours but also differentiate them from malignant liposarcomatous lesions. Here we present a case of intramuscular lipoma of the medial head of Triceps brachii in a 70 year old male clinically mimicking as nerve sheath tumour of the ulnar nerve.
