Presentation
Pain in the elbow.
Patient Data
Thickening and abnormal intermediate high signal intensity on the fluid sensitive sequences seen at insertion site of the common extensor tendon on the lateral epicondyle, the findings are typical of lateral epicondylitis. Moreover, there is focal thickening and increased T2 signal intensity of the ulnar nerve in the cubital tunnel, the finding is of unclear significance and may suggest ulnar neuritis in the appropriate clinical setting. Trace amount of joint effusion is seen.
Case Discussion
Lateral epicondylitis is also called tennis elbow. The term lateral epicondylosis is preferred since there is usually no element of tendon inflammation. On imaging it usually appears as thickening and intermediate increased T2 signal intensity. The presence of fluid signal within the tendon is suggestive of tendon tear.
