42-year-old male with shoulder pain. ROTATOR CUFF: There is thickening and increased signal abnormality indicating moderate to severe tendinosis of the supraspinatus tendon. There is increased fluid signal abnormality consistent with a undersurface fraying of the supraspinatus tendon. The supraspinatus muscle belly appears within normal limits. The infraspinatus muscle and tendon appear intact. The teres minor tendon appears intact. There is mild fatty atrophy of the teres minor muscle belly. There is increased signal abnormality within the subscapularis tendon likely representing tendinosis. There is linear increased fluid signal intensity within the superior fibers of the subscapularis tendon consistent with interstitial tearing. The subscapularis muscle belly appears within normal limits.SUPRASPINATUS OUTLET: Degenerative changes affect the acromioclavicular joint which results in impression along the superior fibers of the supraspinatus muscle. There is a small amount of fluid within the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Although this examination was not protocoled for evaluation of the glenoid labrum, there is irregularity and heterogeneity of the glenoid labrum, consistent with degenerative tearing.BICEPS TENDON: The intra-articular portion of the long head of the biceps tendon is poorly visualized which may reflect chronic tendon rupture. ADDITIONAL
1. Findings suggestive of tendinosis and undersurface fraying of the supraspinatus tendon and interstitial tearing of the subscapularis tendon, without evidence of a near full-thickness or full-thickness rotator cuff tear.2. Findings suggestive of complete rupture of the intra-articular portion of the tendon of the long head of the biceps.3. Mild fatty atrophy of the teres minor and posterior deltoid musculature, suggestive of denervation atrophy in the distribution of the axillary nerve.
