47-year-old male with elbow pain and extensor mass. Evaluate tendon tear. LIGAMENTS: The ulnar collateral ligament and radial collateral ligament appear intact within the limitations of this non arthrogram study. TENDONS: The biceps brachii muscle and tendon appear intact. There is mild increased signal abnormality and thickening of the brachialis tendon which may represent mild tendinosis. The brachialis muscle appears intact.There is fluid signal abnormality within the common extensor tendon at the level of its insertion on the lateral epicondyle consistent with a tear, which measures 8 mm in the AP dimension. Some of the fibers of the common extensor tendon can be traced to the level of its insertion on the lateral upper condyle of the humerus.ARTICULAR SURFACES AND BONE: No bone marrow signal abnormality is identified. SURROUNDING STRUCTURES: The remainder of the subcutaneous tissue and muscle is normal in appearance.ADDITIONAL
1. Tearing of the common extensor tendon as described above.2. Findings suggestive of a very mild olecranon bursitis.
