Anconeus epitrochlearis muscle with resultant:
- narrowing of the cubital tunnel
- reduction in perineural ulnar fat
- prominent ulnar nerve with increased signal intensity
Small volume joint effusion in radio-capitellar joint space.
The superficial radial and posterior interosseous nerves appear normal in size and signal intensity. No abnormal vascular loop.
The median nerve shows normal signal intensity. It shows a normal course between the pronator teres and brachialis muscle. Also, it shows normal contact with the brachial vessels.
No medial epicondyle osteophytic spur, no thickening of the posterior bundle fibres of the ulnar collateral ligament, no atrophy of the flexor carpi ulnaris or flexor digitorum profundus muscles.
