Pain. Rotator cuff injury? ROTATOR CUFF: The supraspinatus tendon and muscle appear normal. There is mild intermediate signal intensity within the insertional fibers of the infraspinatus tendon suggesting mild tendinosis with mild edema-type signal in the underlying humeral head, but I see no fluid-filled rotator cuff tear. The infraspinatus muscle appears normal. The teres minor muscle and tendon appear normal. The subscapularis tendon appears slightly thickened, but I suspect this is due to internal rotation of the humerus; I see no tear, and the subscapularis muscle appears normal.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. I see no fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is within normal limits. Mild osteoarthritis affects the glenohumeral joint with a small subchondral cyst in the superior aspect of the glenoid. Mild intermediate signal intensity within the superior labrum and blunting of the anterior inferior labrum suggests degeneration, but I see no fluid-filled labral tear.BICEPS TENDON: Given the limitations of a nonarthrogram study, the tendon of long head of the biceps appears normal.
1.Mild insertional tendinosis of the infraspinatus, but no rotator cuff tear is evident.2.Mild osteoarthritis of the acromioclavicular and glenohumeral joints with other findings as above.
