82-year-old male with persistent right shoulder pain. ROTATOR CUFF: There is partial thickness undersurface tearing of the supraspinatus at the level of the insertion on the greater tuberosity involving less than one half of the tendon width. There is bursal surface fraying of the distal supraspinatus at the level of its insertion as well. There is thickening and intermediate signal intensity within the supraspinatus indicating moderate tendinosis. There is a tiny insertional tear of the anterior fibers of the infraspinatus measuring approximately 3 mm in AP dimension The infraspinatus muscle and tendon otherwise appear intact. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: There is a trace amount of fluid within the subacromial subdeltoid bursa. Moderate degenerative changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. There is a small glenohumeral joint effusion with foci of low signal intensity internally, suggesting a synovitis. Mild osteoarthritis affects the glenohumeral joint. There are subchondral cysts within the humeral head.BICEPS TENDON: The tendon of the long head of the biceps appears intact. There is circumferential fluid within the tendon sheath of the long head of the biceps indicating a tenosynovitis ADDITIONAL
1. Partial-thickness tearing and bursal surface fraying of the supraspinatus without evidence of a full-thickness rotator cuff tear or retraction.2. Small glenohumeral joint effusion with findings indicating a synovitis.3. Osteoarthritis of the right shoulder.
