Female 37 years old Reason: Right shoulder rotator cuff injury History: Right shoulder pain. ROTATOR CUFF: There is focal poorly defined increased signal intensity seen on the fluid sensitive sequences along the myotendinous junction of the supraspinatus tendon that may represent a strain or perhaps focal degeneration, but we see no discrete tear. There is an insertional undersurface tear of the posterior fibers of the infraspinatus tendon involving just over 50% of the tendon thickness, but sparing the bursal surface fibers. The tear measures approximately 8 mm in the craniocaudal dimension. There is a cyst in the underlying humeral head. There is mild atrophy of the infraspinatus muscle.The teres minor muscle and tendon appear intact.There is thickening and increased signal intensity of the subscapularis tendon that extends into the subscapularis muscle which we suspect is iatrogenic due to infiltration of gadolinium during the procedure.We see no findings to suggest a full thickness rotator cuff tear.SUPRASPINATUS OUTLET: The acromioclavicular joint appears normal. We see no gadolinium within the subacromial/subdeltoid bursa. There is mildly increased signal intensity within the subacromial/subdeltoid bursa seen on the fluid sensitive sequences that may represent a mild bursitis.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is increased signal intensity and deformity of the anterior superior labrum that may represent a tear, but is of uncertain clinical significance. The inferior labrum appears normal. There is minimal posterior translation of the humeral head relative to the center of the glenoid.BICEPS TENDON: The tendon of the long head of the biceps is intact. ADDITIONAL
