Distal ulnar-nerve palsy has been reported secondary to occupational trauma, thromboangiitis, ganglion, and anatomical abnormalities of the ulnar tunnel. Although lipomas have been reported as the cause of sensory ulnar-tunnel syndromes, we believe this is the first isolated motor palsy withoout sensory deficit to be reported secondary to a lipoma in the ulnar tunnel.
