39-year-old female patient with continued pain after left shoulder arthroscopy partial rotator cuff repair. Evaluate rotator cuff. ROTATOR CUFF: There is linear fluid signal intensity within the anterior fibers of the distal supraspinatus tendon at its insertion indicating a tear. The tear involves the majority of the thickness of the tendon, although the anterior and bursal surface fibers may be spared. We see no frank retraction of the tendon. The tear is approximately 1 cm in AP dimension. There is signal abnormality in the underlying greater tuberosity likely representing cysts and edema. Mild tendinosis affects the adjacent tendon. There is mild fatty infiltration along the myotendinous junction of the supraspinatus muscle, but the muscle otherwise appears normal. The infraspinatus, teres minor, and subscapularis muscles and tendons appear intact.SUPRASPINATUS OUTLET: The acromioclavicular joint appears normal. There is a small amount of fluid in the subacromial bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is normal. We see no joint effusion. The labrum appears normal given limitation of a non-arthrogram study.BICEPS TENDON: The biceps tendon appears intact. A small amount of fluid in the biceps tendon sheath is of doubtful clinical significance.ADDITIONAL
Insertional tear, perhaps "concealed", of the distal fibers of the distal supraspinatus tendon and other findings as described above.
