Ulnar neuropathy assessment can be challenging imaging wise.

However, the radiologist should evaluate the ulnar nerve in the following anatomical regions:

• medial intermuscular septum - arcade of Struthers
• medial epicondyle - osteophytic spur or bony growth
• cubital tunnel
• flexor-pronator aponeurosis between the heads of the flexor carpi ulnaris

If the above four regions show no compression features, look for ulnar nerve subluxation, humerus fracture, ganglion cyst, synovitis, locoregional infection or tumor and nerve intrinsic causes (like tumors).

Also, a clinical history of overuse (repetitive elbow flexion) should also be ruled out.
