73 year old female. Right shoulder pain/weakness. Evaluate for rotator cuff pathology. ROTATOR CUFF: Supraspinatus: Complete tear of the supraspinatus tendon from its insertion on the greater tuberosity with retraction to the level of the glenohumeral joint. There is moderate fatty atrophy of the supraspinatus muscle.Infraspinatus: There is a near complete to complete tear of the infraspinatus tendon with similar retraction. Moderate to severe fatty atrophy of the infraspinatus muscle.Teres minor: The tendon and muscle are intact.Subscapularis: Apparent thickening and mild increased signal intensity of the subscapularis tendon, likely represents a combination of tendinosis and redundancy as a result of internal rotation of the humerus. The subscapularis muscle appears intact.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint with spurring of the anterior aspect of the acromion process. A small amount of fluid in the subacromial/subdeltoid bursa is noted. The humeral head is high riding with narrowing of the acromiohumeral interval to 1 mm.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is severe osteoarthritis of the glenohumeral joint with areas of full-thickness cartilage loss and there is signal abnormality in the medial aspect of the humeral head that is likely degenerative in etiology. The humeral attachment of the anterior aspect of the inferior capsule is indistinct and may be partially torn. There is a small amount of fluid in the glenohumeral joint. The labrum is attenuated, likely reflecting degenerative tearing.BICEPS TENDON: The biceps tendon is not well seen in the rotator cuff interval, and a tear cannot be excluded.ADDITIONAL
Massive rotator cuff tear and severe rotator cuff arthropathy, as described above.
