Evaluate for rotator cuff pathology, infraspinatus atrophy. ROTATOR CUFF: There is a full thickness, transverse tear of the supraspinatus tendon with retraction and atrophy of the muscle. There are questionable residual fibers anteriorly. There is a complete transverse tear of the infraspinatus tendon with retraction and atrophy of the muscle. The teres minor muscle and tendon are intact. There is marked thickening and increased T2 signal within the subscapularis tendon compatible with marked tendinosis. SUPRASPINATUS OUTLET: There is moderate osteoarthritis of the acromioclavicular joint with joint space narrowing and subchondral cyst formation.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is superior subluxation of the humeral head from the glenoid. There is a moderate glenohumeral joint effusion.There is diffuse degenerative changes of the labrum.BICEPS TENDON: No significant abnormality noted. ADDITIONAL
