80-year-old male with pain. Evaluate for rotator cuff tear. ROTATOR CUFF: There is a large full-thickness tear of the anterior fibers of the supraspinatus tendon at the level of its insertion on the greater tuberosity measuring approximately 17 mm in AP dimension, with approximately 1.8 cm of retraction. There is increased signal abnormality within the supraspinatus muscle which may suggest an acute component. There is mild fatty infiltration of the supraspinatus muscle at the level of the myotendinous junction.The infraspinatus muscle appears intact. There is thickening and increased signal abnormality within the infraspinatus tendon indicating moderate tendinosis. There is full-thickness tearing of the anterior fibers of the infraspinatus tendon at the level of its insertion on the greater tuberosity measuring approximately 3 mm in AP dimension. There is near full-thickness undersurface tearing of the subscapularis tendon at the level of its insertion on the lesser tuberosity. There is associated medial subluxation of the long head of the biceps tendon. The teres minor muscle and tendon appear intact.SUPRASPINATUS OUTLET: There is a small amount of fluid within the subacromial subdeltoid bursa. Moderate degenerative changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is linear increased signal abnormality within the superior labrum indicating a tear, within the limitations of a non arthrogram study. The glenohumeral joint alignment is anatomic.BICEPS TENDON: Note is made of medial subluxation of the long head of the biceps tendon. There is thickening and intermediate signal abnormality within the long head of the biceps tendon indicating moderate tendinosis. There is circumferential fluid within the tendon sheath of the long head of the biceps which may reflect fluid extension from the glenohumeral joint versus tenosynovitis.ADDITIONAL
1. Full-thickness rotator cuff tear with retraction and tendinosis as described.2. Medial subluxation of the long head of the biceps tendon with associated biceps tendinosis.3. Small glenohumeral joint effusion.
