Reason: Evaluate for rotator cuff tear and assess degree of arthritis History: Left shoulder pain after injury. ROTATOR CUFF: Increased signal intensity within the anterior fibers of the supraspinatus tendon compatible with tendinosis. Small foci of intermediate signal intensity along the articular and bursal surfaces of the supraspinatus tendon are compatible with fraying/superficial tearing. There is also a focus of intermediate signal intensity within the distal fibers of the supraspinatus tendon at its insertion which may represent a small concealed interstitial tear. We see no full-thickness supraspinatus tendon tear. The supraspinatus muscle is within normal limits for age. Undersurface fraying of the supraspinatus tendon extends into the anterior fibers of the infraspinatus tendon but we see no full-thickness infraspinatus tendon tear. There is perhaps mild fatty atrophy of the infraspinatus muscle. The teres minor muscle and tendon are intact. Streaky foci of increased signal intensity within the distal fibers of the subscapularis tendon likely representing a combination of tendinosis and interstitial tearing. There is mild fatty atrophy of the subscapularis muscle.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the AC joint. Mild increased signal intensity within the subacromial/subdeltoid bursa on the fluid sensitive sequences as well as a small amount of fluid signal intensity may reflect mild bursitis.GLENOHUMERAL JOINT AND GLENOID LABRUM: Alignment of the glenohumeral joint is normal. There is a small joint effusion. Mild osteoarthritis affects the glenohumeral joint. Intermediate signal intensity between the superior labrum and underlying glenoid is suggestive of a tear. Mild degeneration of the inferior labrum.BICEPS TENDON: At least a partial-thickness longitudinal tear of the tendon of the long head of the biceps at its transition from the intertubercular groove to the rotator interval. Distal to the biceps tendon tear, the biceps tendon is thickened suggestive of tendinosis. Fluid signal intensity surrounding the biceps tendon may reflect tenosynovitis. There is perching of the tendon upon the lesser tuberosity suggesting a pulley lesion. Edema within the lesser tuberosity likely is reactive in etiology.
1.Tear of the long head of the biceps tendon.2.Tendinosis and partial-thickness tearing of the rotator cuff as described above with no discrete full thickness rotator cuff tear.3.Additional degenerative arthritic changes as described above.
