68-year-old female patient with left shoulder pain. Evaluate for rotator cuff tear. ROTATOR CUFF: There is thickening and increased signal intensity of the supraspinatus tendon indicating moderate tendinosis with mild undersurface fraying, but we see no discrete fluid-filled tear. The supraspinatus muscle is otherwise within normal limits. Increased signal intensity within the infraspinatus tendon represents additional mild tendinosis with perhaps mild undersurface fraying, but we see no fluid-filled full-thickness tear. There is mild fatty atrophy along the myotendinous junction of the infraspinatus muscle, otherwise it appears normal. The teres minor muscle and tendon are normal. There is thickening and increased signal intensity of the subscapularis tendon which likely represents a combination of tendinosis and redundancy due to internal rotation.SUPRASPINATUS OUTLET: No significant fluid is identified within the subdeltoid/subacromial bursa. Mild to moderate osteoarthritis affects the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Moderate to severe osteoarthritis affects the glenohumeral joint with subchondral cyst formation in the superior humeral head and glenoid as well as osteophytes. We see no large joint effusion, but intermediate to high signal intensity extending from the joint to the subscapular recess likely represents focal synovitis. Evaluation of the labrum is limited due to lack of articular contrast, but blunting and increased signal intensity of the anterior and posterior labrum likely represents degeneration. BICEPS TENDON: Mild increased intensity within the intra-articular portion of the long head of the biceps suggests mild tendinosis.ADDITIONAL
1. Limited evaluation as described above.2. Osteoarthritis of the shoulder as described above.3. Rotator cuff tendinosis and possible undersurface fraying without discrete fluid-filled tear.4. Loss of fat beneath the coracohumeral ligament can be seen in patients with adhesive capsulitis.
