39-year-old male with shoulder pain. Evaluate for rotator cuff tear. ROTATOR CUFF: There is thickening and intermediate signal abnormality within the supraspinatus and infraspinatus indicating mild tendinosis. There is perhaps mild undersurface fraying of the supraspinatus tendon. The supraspinatus muscle and tendon otherwise appears intact. The infraspinatus muscle and tendon appear intact. The teres minor muscle and tendon appear intact. The subscapularis muscle and tendon appear intact.SUPRASPINATUS OUTLET: No significant fluid is identified within the subacromial subdeltoid bursa. Mild osteoarthritic changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Heterogeneous bone marrow signal abnormality may reflect residual islands of red marrow. The glenohumeral joint alignment is anatomic. Heterogeneity and increased signal abnormality within the anterior labrum may reflect degeneration/tearing, within the limitations of this non arthrogram study. There is subchondral cyst formation within the posterior superior humeral head.BICEPS TENDON: The tendon of the long head of the biceps appears intact. ADDITIONAL
1. Mild rotator cuff tendinosis and undersurface fraying without evidence of a full-thickness rotator cuff tear. 2. Findings suggestive of degeneration/tearing of the anterior glenoid labrum within the limitations of a non arthrogram study. 3. Mild acromioclavicular joint osteoarthritis.4. Nonspecific subchondral cyst formation within the posterior superior humeral head can be seen in internal impingement in the correct clinical setting.
