Female 75 years old; Reason: left shoulder pain, severe DJD ROTATOR CUFF: There is a focal high signal intensity vertically traversing the supraspinatus tendon at the 12 o'clock position situated approximately 3 cm proximal to the tendon insertion, suggestive of a full-thickness defect. There is little, if any, frank tendon retraction proximal to the site of this tear, although we suspect that there may be delamination of the undersurface fibers with retraction distally from the greater tuberosity. There is also undersurface insertional tearing more anteriorly, best seen on the sagittal oblique sequences. Additional increased signal within the supraspinatus tendon likely reflects tendinosis. There is associated cyst formation in the underlying humeral head. The supraspinatus muscle is mildly atrophic. Moderate tendinosis is noted of the infraspinatus, with undersurface fraying. Cyst formation along the myotendinous junction is indicative of interstitial tearing. Mild atrophy of the infraspinatus is noted. Mild atrophy of the teres minor is noted, but the teres minor tendon is intact. There is increased signal within and thickening of the distal subscapularis tendon, indicating moderate tendinosis. The subscapularis muscle appears normal.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. Trace fluid is seen within the subacromial/subdeltoid bursa. GLENOHUMERAL JOINT AND GLENOID LABRUM: Moderate osteoarthritis affects the glenohumeral joint, with subchondral cysts in the glenoid. Increased signal within the posterior labrum likely reflects tearing, with perhaps minimal posterior translation of the humeral head relative to the center of the glenoid. Blunting of the anterior labrum is likely degenerative. No glenohumeral joint effusion is present.BICEPS TENDON: The tendon of the long head of the biceps is intact.ADDITIONAL
1. Moderate osteoarthritis of the glenohumeral and acromioclavicular joints.2. Rotator cuff tendinosis and tears, as described above.3. Other findings as described above.
