66-year-old male with weakness and elevated CK to greater than 1000. ROTATOR CUFF: There is a near full thickness bursal surface tear of the supraspinatus tendon just proximal to its insertion on the greater tuberosity without significant retraction. Some of the articular surface fibers can be traced to their insertion on the greater tuberosity. The supraspinatus muscle appears intact. There is thickening and intermediate signal intensity within the infraspinatus consistent with mild tendinosis. The infraspinatus muscle and tendon appear intact. There is thickening and intermediate signal abnormality within the subscapularis indicating mild tendinosis. The subscapularis and teres minor muscle and tendons appear intactSUPRASPINATUS OUTLET: There is a small amount of fluid within the subacromial subdeltoid bursa. Mild degenerative changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. Although this examination was not protocoled for evaluation of the glenoid labrum, the labrum appears intact. There is subchondral cyst formation within the humeral head.BICEPS TENDON: The tendon of the long head of the biceps appears intact. ADDITIONAL
1. Near full-thickness tear of the supraspinatus tendon as described above without significant retraction.2. No fatty atrophy or increased signal abnormality is identified within the imaged musculature of the right shoulder.
