Right shoulder pain and stiffness. ROTATOR CUFF: There is thickening and intermediate signal intensity of the supraspinatus tendon indicating mild-moderate tendinosis. In addition, there is high signal intensity within the distal fibers of the tendon indicating insertional tearing that appears predominantly interstitial in nature though may have small branching component that extend through both the articular and bursal surface fibers. We see no frank retraction of the supraspinatus tendon. We estimate the tear measures approximately 2 cm in the AP dimension. The supraspinatus muscle appears intact. There is thickening of the distal infraspinatus tendon indicating mild tendinosis with longitudinally increased signal intensity suggesting mild interstitial tearing. The infraspinatus muscle appears intact. The teres minor and subscapularis muscle and tendons are intact.SUPRASPINATUS OUTLET: There is mild-moderate osteoarthritis of the acromioclavicular joint with capsular hypertrophy associated with mild impression of the superior fibers of the supraspinatus. An os acromiale is present. A small amount of fluid is present in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is within normal limits. No joint effusion. Abnormal signal intensity within the superior labrum is compatible with a tear. The inferior labrum appears intact.BICEPS TENDON: Given limitations of a non arthrogram study, the tendon of long head of the biceps appears normal.
