46-year-old female with shoulder pain. ROTATOR CUFF: There is a full-thickness insertional tear of the supraspinatus tendon extending slightly posterior to involve the anterior fibers of the infraspinatus as well, measuring approximately 13 mm in the AP dimension, with approximately 1 cm of retraction of the bursal surface fibers. There is increased signal abnormality of the supraspinatus suggesting mild tendinosis. There is minimal fatty atrophy of the supraspinatus muscle at the level of the myotendinous junction. The supraspinatus muscle appears intact. There is mild interstitial tearing and fatty infiltration of the infraspinatus along the myotendinous junction. The teres minor and subscapularis muscles and tendons appear intact.SUPRASPINATUS OUTLET: There is a small amount of fluid within the subacromial subdeltoid bursa. Minimal osteoarthritis affects the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is within normal limits. Given the limitations of a non arthrogram study, we see no evidence of a labral tear. There is no joint effusion.BICEPS TENDON: The tendon of the long head of the biceps is normal in appearance.
Full-thickness insertional tear of the supraspinatus/infraspinatus with mild retraction. Other findings as described above.
