51-year-old female with left shoulder pain, evaluate for left shoulder rotator cuff or labral tear ROTATOR CUFF: There is a small amount of gadolinium entering the distal fibers of the supraspinatus tendon indicating a poorly defined undersurface tear that extends longitudinally for approximately 8 mm within the articular surface fibers of the tendon and with additional extension towards the bursal surface fibers, but without disruption of the most superficial fibers. No full thickness tear identified. The remainder of the supraspinatus tendon and muscle appears normal.The infraspinatus tendon is intact. There is minimal fatty infiltration along the myotendinous junction but otherwise the muscle appears normal.The teres minor tendon and muscle are intact.The subscapularis tendon and muscle are intact.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the AC joint. Trace fluid in the subacromial bursa is of doubtful clinical significance, and no gadolinium is seen within the bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The entire anterior labrum is separated from the glenoid indicating a Bankart lesion; the anterior aspect of the glenoid appears abnormally flattened suggesting a Bankart fracture that would be better evaluated with CT if clinically warranted. There is globular increased signal intensity of the superior labrum indicating degeneration and tearing that extends into the posterior labrum to approximately the 9 to 10 o'clock position. There is also a Hill-Sachs defect.BICEPS TENDON: There is increased signal intensity within the tendon of the long head of the biceps likely representing tendinosis or perhaps iatrogenic injection of gadolinium into the tendon during the procedure.
1. Bankart fracture and labral tears as described above as well as Hill-Sachs deformity.2. Small partial thickness tear of the supraspinatus tendon as described above.3. Mild osteoarthritis of the acromioclavicular joint and other findings as described above.
