82-year-old male with pain with elevation of the left shoulder above 90 degrees. Evaluate for possible rotator cuff tear. ROTATOR CUFF: There is a full-thickness with near full width tear of the supraspinatus tendon with associated high riding humeral head. There is a full-thickness tear of the subscapularis tendon. There is small intrasubstance tearing of the infraspinatus tendon. The teres minor tendon appears normal. There is severe fatty atrophy of the supraspinatus muscle. There is mild fatty atrophy of the teres minor and infraspinatus muscles.SUPRASPINATUS OUTLET: There is marked narrowing of the supraspinatus outlet secondary to the aforementioned rotator cuff tear with high riding humeral head. Moderate osteoarthritic changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Moderate osteoarthritic changes affect the glenohumeral joint. As above there is a high riding humeral head secondary to the aforementioned rotator cuff tears. There is globular tearing of the glenoid labrum. There is a small glenohumeral joint effusion.BICEPS TENDON: The long head of the biceps tendon is torn.ADDITIONAL
1. Full-thickness tear of the supraspinatus and subscapularis tendons as well as small intrasubstance tearing of the infraspinatus tendon with associated high riding humeral head. Fatty infiltration of the rotator cuff musculature, most prominent at the supraspinatus muscle.2. The long head of the biceps tendon is torn.3. Moderate osteoarthritic changes affect the acromioclavicular glenohumeral joints.
