Intraneural Ganglion of Ulnar Nerve in Proximal Forearm: Case Report

ABSTRACT

Cubital tunnel syndrome is a compressive neuropathy of the ulnar nerve posterior to the medial epicondyle of the elbow. The etiology is either idiopathic, or secondary to deformity, ectopic ossification, space occupying lesion, or osteophytes in elbow osteoarthritis. As a rare cause of cubital tunnel syndrome, we report an intraneural ganglion of ulnar nerve developed in proximal forearm with symptoms of ulnar neuropathy.
