Reason: cuff tear? History: pain ROTATOR CUFF: There is partial thickness tearing of the articular surface fibers of the supraspinatus just proximal to the level of its insertion on the greater tuberosity involving approximately 50% of the tendon width, measuring approximately 2 cm in AP dimension. There is no significant retraction. There is also thickening and intermediate signal intensity within the supraspinatus indicating moderate tendinosis. The infraspinatus muscle and tendon appear intact. The teres minor muscle and tendon appear intact. There is undersurface fraying of the subscapularis just proximal to its insertion on the lesser tuberosity.SUPRASPINATUS OUTLET: There is a trace amount of fluid within the subacromial subdeltoid bursa. Moderate degenerative changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is a full-thickness articular cartilage cleft along the inferior margin of the glenoid with underlying degenerative subchondral signal abnormality and cyst formation. There is degeneration/degenerative tearing of the inferior labrum within the limitations of a non arthrogram study.BICEPS TENDON: There is deformity and increased signal abnormality within the intra-articular portion of long head biceps tendon consistent with a longitudinal split tear. There is a small amount of circumferential fluid within the tendon sheath which may reflect fluid extension from the joint versus a tenosynovitis. ADDITIONAL
1. Tendinosis and partial thickness tearing of the supraspinatus without evidence of a full-thickness rotator cuff tear or retraction.2. Osteoarthritis of the shoulder and degeneration/degenerative tearing of the glenoid labrum.3. Longitudinal split tear of the intra-articular portion of the long head of the biceps tendon and probable biceps tendon tenosynovitis. Other findings as described.
