Shoulder pain, evaluate rotator cuff. ROTATOR CUFF: Moderate tendinosis affects the anterior fibers of the supraspinatus tendon distally, but we see no discrete tear. The supraspinatus muscle appears normal. The infraspinatus as well as teres minor muscles and tendons appear normal. There is perhaps mild tendinosis of the distal fibers of the subscapularis tendon, but we see no discrete tear. The subscapularis muscle appears normal.SUPRASPINATUS OUTLET: There is edema within the distal clavicle as well as small subchondral cysts/erosions. There is also edema to lesser degree within the acromial process particularly at the acromioclavicular joint. There is also edema within the capsular structures of the acromioclavicular joint. The coracoclavicular ligaments appear intact. There is perhaps a tiny amount of fluid within the acromioclavicular joint itself. Trace fluid is present within the subacromial subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The anterior capsular structures appear thickened which may in part be due to the arm being held in internal rotation for the study. There is mild irregularity and increased signal intensity of the anterior labrum which may reflect mild degeneration but is not necessarily of clinical significance. A small amount of fluid is present within the glenohumeral joint without frank effusion.BICEPS TENDON: There is mildly increased signal intensity within the tendon of the long head of biceps at the transition from the rotator interval to the intertubercular groove suggesting mild-moderate tendinosis.
1.Osteoarthritis of the acromioclavicular joint with edema in the distal clavicle, acromion, and joint capsule structures. These findings may reflect sequela of prior trauma or chronic instability.2.Supraspinatus and biceps tendinosis and other findings as described above.
