Intraneural cavernous haemangioma of ulnar nerve and cubital tunnel syndrome

Abstract Cubital tunnel syndrome due to cavernous haemangioma of ulnar nerve is a rare condition. In the present study, we report a case of intraneural haemangioma of the ulnar nerve at the elbow in an Iranian woman. A 40-year-old woman with a left elbow pain, ulnar nerve thickness, intrinsic muscle atrophy of the hand and local tenderness was admitted in our hospital. Ultrasound of elbow soft tissue showed a hypoechoic tubular mass (15 × 10 mm) that seen along the ulnar nerve. With the aid of a microscope, removal of tumour with minimal damage to the nerve fascicles was accomplished. Histopathological examination revealed a benign cavernous hemangioma. Nerve compression by an intraneural haemangioma is rare and should be resected with minimal damage to the nerve fascicles. In our cases, dissection was occurred with minimal damage to the nerve fascicles. Postoperative recovery was unremarkable, and the ulnar nerve function remained normal.
