Shoulder pain and limited range of motion. Some sequences are limited by patient motion artifact.ROTATOR CUFF: The supraspinatus muscle and tendon appear intact; the suspected tendinosis and undersurface tearing seen on ultrasound is not evident on this study. There is increased signal intensity along the undersurface of the infraspinatus at its insertion, which may reflect tendinosis or undersurface fraying/insertional tearing (and perhaps representing the suspected abnormality in the posterior supraspinatus seen on US), but we see no full-thickness tear. There is focal scalloping of the underlying humeral head which may reflect old trauma or chronic remodeling, but is not necessarily of any clinical significance. The infraspinatus muscle appears intact. The subscapularis and teres minor muscles and tendons appear intact; the suspected undersurface fraying of the subscapularis tendon seen on the prior ultrasound is not evident on this study, although there are small cysts in the underlying anterior humeral head.SUPRASPINATUS OUTLET: Tiny acromioclavicular joint osteophytes suggest minimal osteoarthritis. There is mild impression upon the superior fibers of the supraspinatus by the distal end of the clavicle. There is increased signal intensity within the distal clavicle on the fluid sensitive sequences, which may represent mild edema or residual red marrow. There is a trace amount of fluid within the subacromial/subdeltoid bursa which is not necessarily of any clinical significance.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. The glenoid labrum appears normal, given the limitations of a non arthrogram study.BICEPS TENDON: The tendon of the long head of the biceps appears intact, within the limitations of a non arthrogram study. The tendon is not well visualized at its transition from the rotator interval to the intertubercular groove, but we see no tendon thickening to confirm tendinosis.ADDITIONAL
Increased signal intensity along the undersurface fibers of the infraspinatus at its insertion could represent tendinosis, fraying, or mild focal articular surface insertional tearing, but we see no full-thickness rotator cuff tear. Other findings as described above.
