Reason: concern for rotator cuff tear History: Pain Some sequences are limited by patient motion artifact.ROTATOR CUFF: There is intermediate signal intensity within the supraspinatus and infraspinatus tendons suggesting mild tendinosis, but we see no tear. On the fat suppressed T2-weighted images, there is slight increase in signal intensity of the infraspinatus as well as the proximal belly of the supraspinatus, and to a lesser degree the posterior fibers of the deltoid musculature. We see no frank fatty atrophy on the T1-weighted images. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. There is mild edema type signal within the subdeltoid bursa which may reflect mild inflammation.GLENOHUMERAL JOINT AND GLENOID LABRUM: The anterior inferior labrum is replaced with intermediate signal intensity suggesting degeneration. The anterior superior labrum is detached from the underlying glenoid which may represent a normal variant sublabral foramen. There is no glenohumeral joint effusion. There are small cysts in the humeral head just above the lesser tuberosity.BICEPS TENDON: The tendon of the long head of the biceps appears intact ADDITIONAL
1. Mild signal abnormality within the supraspinatus, infraspinatus, and posterior deltoid musculature which is nonspecific and could reflect early denervation atrophy. Parsonage-Turner is also included in the differential diagnosis.2. Mild osteoarthritis affects the acromioclavicular joint and there is mild inflammation of the subdeltoid bursa.3. Minimal supraspinatus and infraspinatus tendinosis, but no rotator cuff tear.
