Reason: ?rotator cuff tear, supraspinatus - unable to raise arm, recent h/o injury lifting heavy weight History: left shoulder weakness Several sequences are limited by patient motion artifact.ROTATOR CUFF: There are massive tears of the rotator cuff, with complete tears of the supraspinatus and infraspinatus tendons with retraction to the level of the glenohumeral joint. There is mild to moderate atrophy of the supraspinatus and infraspinatus muscles. There is a full-thickness near-complete tear of the subscapularis tendon with only the most inferior fibers extending to the lesser tuberosity; the majority of the subscapularis tendon fibers are retracted to the level of the glenoid. Moderate to severe fatty atrophy of the subscapularis muscle. Teres minor tendon and muscle are intact. SUPRASPINATUS OUTLET: Moderate osteoarthritis of the acromioclavicular joint. There is a small amount of fluid in the subacromial/subdeltoid bursa containing intermediate signal intensity, likely reflecting bursitis. This fluid extends into and through the acromioclavicular joint resulting in a small fluid collection dorsal to the joint. Humeral head is high riding with the acromiohumeral interval measuring 1 to 2 mm.GLENOHUMERAL JOINT AND GLENOID LABRUM: Small to moderate glenohumeral joint effusion containing small foci of intermediate signal intensity, likely debris. Mild osteoarthritis of the glenohumeral joint. Bone marrow signal is normal.There is increased signal in the anterior and superior labrum, which may reflect degeneration/degenerative tearing.BICEPS TENDON: There is full-thickness rupture of the biceps tendon within the rotator interval. The tendon is not visualized within the bicipital groove.
Massive rotator cuff tear and other findings as above.
