Left shoulder pain ROTATOR CUFF: There is increased intermediate signal intensity and thickening of the supraspinatus and infraspinatus tendons, indicating moderate tendinosis. The increased signal intensity within the supraspinatus tendon extends to the articular surface fibers, suggesting undersurface fraying but we see no discrete tear. There is a small focus of signal abnormality in the underlying humeral head. The supraspinatus and infraspinatus muscles appear normal. The teres minor muscle and tendon appear normal. There is focal increased signal within the undersurface of the subscapularis tendon at its insertion, likely representing tendinosis with a small focus of signal abnormality of the underlying humeral head but we see no discrete tear.SUPRASPINATUS OUTLET: There is an os acromiale. The acromioclavicular joint appears otherwise normal. There is no fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is normal. There is a small amount of fluid in the joint but there is no large effusion. There is perhaps mild fraying of the superior glenoid labrum, however we see no discrete tear.BICEPS TENDON: There is a small amount of fluid within the biceps tendon sheath, raising the possibility of mild tenosynovitis. On the axial sequences there appears to be a longitudinal split in the superior fibers of the biceps tendon but the true clinical significance of this is uncertain.
1. Rotator cuff tendinosis and possible undersurface fraying of the labrum without discrete rotator cuff tear.2. Os acromiale.3. Findings suggestive of a longitudinal split tear of the biceps tendon at its transition from the bicipital groove to the rotator interval.3. Other findings as above.
