58-year-old female with pain. Evaluate for rotator cuff tear. ROTATOR CUFF: There is increased signal intensity within the supraspinatus tendon indicating mild tendinosis, but we see no discrete tear. There is mild fatty infiltration along the myotendinous junction, but otherwise the muscle is normal in appearance. There is mild tendinosis of the infraspinatus tendon. Additionally, there are small foci of immediate signal intensity within the insertional fibers of the tendon that may represent small concealed tears or more focal regions of tendinosis, but we see no discrete fluid-filled or full-thickness tears. There are small underlying subchondral cysts within the humeral head. There is mild fatty infiltration along the myotendinous junction, but the muscle of the infraspinatus otherwise appears normal. There is increased signal intensity within the distal fibers of the subscapularis, likely representing a combination of tendinosis and interstitial tearing, perhaps extending to the articular surface. The teres minor muscle and tendon appear intact.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid within the subacromial/subdeltoid bursa which is of questionable clinical significance.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. There is mild osteoarthritis of the glenohumeral joint. There is a small amount of fluid within the joint but no large effusion. There is globular and linear signal abnormality within the superior labrum which likely represents a combination of degeneration and degenerative tearing.BICEPS TENDON: There is abnormal signal intensity within the tendon of the long head of the biceps, particularly at its transition from the rotator interval to the intertubercular sulcus, likely representing a combination of degeneration and partial thickness tearing. There is fluid signal intensity surrounding the tendon within the bicipital groove suggesting a mild tenosynovitis.ADDITIONAL
1. Tendinosis and possible mild superimposed insertional tearing of the rotator cuff as described above; however, we see no fluid-filled or full-thickness rotator cuff tear.2. Moderate tendinosis and partial-thickness tearing of the long head of the biceps, particularly at its transition from the rotator interval to the bicipital groove, with fluid in the tendon sheath suggesting tenosynovitis.3. Mild osteoarthritis of the glenohumeral and acromioclavicular joints with degeneration/degenerative tearing of the superior labrum.4. Subcoracoid bursitis.
