Reason: evaluate right shoulder for rotator cuff tear/assess quality of rotator cuff muscle and tendon History: right shoulder pain and weakness. ROTATOR CUFF: Complete full thickness tears of the supraspinatus and infraspinatus tendons with retraction of the tendons to the glenohumeral joint. Severe fatty atrophy of the supraspinatus and infraspinatus muscles. The teres minor tendon and muscle are intact. There is also a complete or near complete tear of the subscapularis tendon with retraction to the glenohumeral joint, although a few inferior fibers may extend to the humeral neck. Mild fatty atrophy of the subscapularis muscle.SUPRASPINATUS OUTLET: Moderate to severe acromioclavicular joint osteoarthritis. Small amount of fluid within the subacromial/subdeltoid bursa. The humeral head is high riding and appears to abut the undersurface of the acromion process.GLENOHUMERAL JOINT AND GLENOID LABRUM: As previously mentioned, the humeral head is high riding, but we see no frank dislocation. Mild osteoarthritis affects the glenohumeral joint. There is a small joint effusion. Small foci of signal abnormality in the lesser trochanter and along the posterior aspect of the humeral head likely are secondary to overlying rotator cuff pathology. We see no fluid signal intensity anteriorly in the labrum, although intermediate intrasubstance signal intensity may reflect mild degeneration.BICEPS TENDON: The long head of the biceps tendon is dislocated medially from the bicipital groove. Mild increased signal intensity within the tendon suggests mild tendinosis.ADDITIONAL
Massive rotator cuff tear with marked fatty atrophy of the supraspinatus and infraspinatus muscles and other findings as described above.
