56-year-old female with pain. ROTATOR CUFF: There is thickening and increased signal intensity of the supraspinatus indicating mild to moderate tendinosis. There is also more focal increased signal intensity within the distal fibers of the tendon, at its insertion, indicating a small insertional tear that appears to involve the majority of the tendon thickness including the bursal surface, but spares the articular surface fibers at their insertion. There is minimal tendon retraction. Slightly more proximally, the articular surface fibers of the tendon are indistinct, suggesting fraying or focal degenerative tearing. The supraspinatus muscle appears intact. There is minimal interstitial tearing along the myotendinous junction of the infraspinatus. There is mild tendinosis of the infraspinatus tendon. The infraspinatus muscle appears normal. The teres minor muscle and tendon appear normal. There is minimal tendinosis of the subscapularis distally, but no tear is evident. The subscapularis muscle appears intact.SUPRASPINATUS OUTLET: There is a trace amount of fluid within the subacromial/subdeltoid bursa. Mild degenerative changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. No joint effusion is evident. There is minimal increased signal intensity within the superior labrum which may reflect degeneration, but we see no fluid-filled labral tear, given the limitations of a non arthrogram study.BICEPS TENDON: Give the limitations of a non arthrogram study, the tendon of the long head of the biceps appears normal.
1. Tendinosis and partial-thickness tearing of the supraspinatus involving both the bursal and undersurface fibers as described above. Other rotator cuff findings as described above.2. Mild osteoarthritis of the acromioclavicular joint and other findings as described above.
