39-year-old male with shoulder pain. Evaluate rotator cuff. ROTATOR CUFF: There is intermediate signal intensity within the supraspinatus tendon indicating mild tendinosis. Best seen on the sagittal oblique images is a 6 mm focus of increased signal intensity along the anterior fibers of the supraspinatus tendon at the greater tuberosity likely representing a concealed interstitial tear with mild edema in the underlying greater tuberosity. The supraspinatus muscle appears normal. The infraspinatus muscle and tendon appear normal. The teres minor muscle and tendon appear normal. There is apparent thickening of the subscapularis tendon which may reflect mild tendinosis but this is likely exaggerated by the arm positioned in mild internal rotation. SUPRASPINATUS OUTLET: There is an os acromiale. Mild edema within the os is present, however to a lesser degree than that seen on the right. We see no frank osteoarthritic changes of the acromioclavicular joint. There is trace fluid in the subdeltoid bursa of questionable clinical significance.GLENOHUMERAL JOINT AND GLENOID LABRUM: Joint alignment is within normal limits. There is a small amount of fluid in the joint with no frank effusion present. There is intermediate signal intensity within the superior labrum which may reflect degeneration or degenerative tearing but we see no fluid filled tear on this non-arthrogram study. The articular cartilage appears normal.BICEPS TENDON: The tendon of the long head of the biceps muscle appears normal.
