57-year-old female with shoulder pain. Evaluate subscapularis/rotator cuff. ROTATOR CUFF: There is thickening and heterogeneity of the supraspinatus tendon and anterior fibers of the infraspinatus tendon indicating moderate tendinosis. There are small cysts along the bursal surface fibers of the supraspinatus and anterior infraspinatus tendon likely due to superficial bursal surface fraying/tearing but we see no full-thickness fluid-filled defect. There is also a small elongated collection along the myotendinous junction of the supraspinatus tendon likely representing interstitial tearing which perhaps extends to the bursal surface fibers. The supraspinatus and infraspinatus muscles appear intact. There is thickening and increased signal intensity of the subscapularis tendon indicating tendinosis. There is additional more focal increased signal intensity within the tendon at its insertion indicating a partial thickness tear with minimal retraction. The subscapularis muscle appears intact. The teres minor muscle and tendon appear intact.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is trace fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Moderate osteoarthritis affects the glenohumeral joint. There is abnormal signal intensity throughout much of the labrum compatible with extensive degenerative tearing. There is a small amount of fluid within the glenohumeral joint with intermediate signal intensity which may reflect synovitis or debris.BICEPS TENDON: There is a small amount of fluid within the tendon sheath of the long head of the biceps. The tendon itself is unremarkable.
1. Osteoarthritis of the glenohumeral and acromioclavicular joints.2. Tendinosis and partial-thickness tearing of the rotator cuff, including the subscapularis tendon, as described above.
