Female, 57 years old. Pain. ROTATOR CUFF: There is a focal full-thickness tear of the anterior fibers of the supraspinatus tendon at their insertion on the greater tuberosity with up to 1 cm of retraction. The tear is approximately 1 cm in AP dimension. Increased signal intensity more proximally within the tendon represents mild tendinosis. There is minimal if any fatty atrophy of the supraspinatus muscle. There is a small undersurface tear of the infraspinatus tendon at its insertion on the greater tuberosity involving less than 50% of the tendon thickness. The tear itself is approximately 5 mm in diameter with cyst formation in the underlying humeral head. There is mild tendinosis of the infraspinatus tendon more proximally and perhaps minimal fatty atrophy of the infraspinatus muscle. The teres minor tendon and muscle appear normal. The subscapularis tendon and muscle appear normal.SUPRASPINATUS OUTLET: The acromioclavicular joint appears normal for age. There is a small amount of fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is normal. The superior labrum appears blunted posteriorly likely reflecting degenerative tearing. The inferior labrum appears intact.BICEPS TENDON: The tendon of the long head of the biceps appears normal.
Full-thickness tear of the anterior insertional fibers of the supraspinatus tendon and a small undersurface insertional tear of the infraspinatus tendon. Other findings as above.
