Right shoulder pain and weakness ROTATOR CUFF: Although we see no fluid-filled full-thickness rotator cuff tear, there is intermediate signal intensity focally separating the distal fibers of the supraspinatus tendon from its insertion on the greater tuberosity. There is extension of these changes across the full-thickness of the tendon and this could reflect focal insertional tendinosis or perhaps a rim-rent type tear that has filled with granulation tissue; however, lack of fluid in the adjacent subdeltoid bursa argues against a tear. There is additional undersurface fraying of the supraspinatus tendon. More posteriorly within the anterior fibers of the infraspinatus tendon is a 3 mm focus of fluid signal intensity at its insertion representing a small concealed insertional tear. Additional intermediate signal intensity of the infraspinatus represents tendinosis. A small cyst is present within the underlying humeral head. There is mild fatty infiltration along the myotendinous junction of the infraspinatus muscle but the remaining infraspinatus and supraspinatus muscles are intact. The teres minor tendon and muscle are normal. There is increased signal intensity and thickening of the distal fibers of the subscapularis indicating tendinosis with small foci of fluid signal intensity within the superior fibers of the tendon representing small insertional tears. The subscapularis muscle is normal.SUPRASPINATUS OUTLET: Mild to moderate osteoarthritis affects the acromioclavicular joint. There is no frank fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is deformity and abnormal signal intensity of the anterior labrum indicating tearing. There is also linear signal intensity partially separating the posterior superior labrum from the glenoid compatible with a SLAP tear. A small amount of fluid is present within the glenohumeral joint, particularly in the subscapular recess, but there is no large joint effusion.BICEPS TENDON: There is increased signal intensity and thickening of the long head of the biceps tendon as it courses through the rotator interval and into the intertubercular groove representing moderate tendinosis and perhaps longitudinal tearing. ADDITIONAL
1. Moderate tendinosis and perhaps longitudinal tearing of the long head of the biceps tendon.2. Labral tearing as above.3. Rotator cuff tendinosis and tearing as described above. There is no fluid-filled full-thickness rotator cuff tear.
