Male, 67 years old. Shoulder pain. Previous subscapularis lesion. Some sequences are limited by patient motion artifact.ROTATOR CUFF: There is thickening and increased signal intensity of the supraspinatus tendon indicating moderate tendinosis. At the 12:00 position, there is an insertional tear of the supraspinatus tendon on the greater tuberosity that involves the bursal surface fibers but spares the articular surface fibers. The tear traverses more than 50% of the tendon thickness and continues longitudinally as insertional delamination for approximately 1 cm. The tear is just under 1 cm in AP diameter. The supraspinatus muscle appears normal. There is thickening and increased signal intensity of the infraspinatus tendon, indicating mild tendinosis. There is an approximately 8 mm linear tear of the infraspinatus tendon at its insertion. There is severe fatty atrophy of the infraspinous muscle. The teres minor tendon and muscle appear normal. Linear increased signal intensity within the distal subscapularis tendon suggests insertional tearing. We also suspect that there is undersurface fraying of the distal subscapularis tendon with cyst formation in the underlying humeral head. The subscapularis muscle appears normal.SUPRASPINATUS OUTLET: There is an os acromiale. Mild osteoarthritis affects the acromioclavicular joint. There is trace fluid in the subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthritis affects the glenohumeral joint. There is a small amount of fluid in the joint. Degeneration/degenerative tearing of the superior labrum appears similar to the prior study.BICEPS TENDON: The tendon of the long head of the biceps is intact.
Partial thickness rotator cuff tearing as above that appears to have progressed slightly when compared to the prior study. Other findings as above.
