Pain and weakness. Question of rotator cuff tear. ROTATOR CUFF: There is mild thickening and increased signal intensity of the supraspinatus and infraspinatus tendons indicating mild tendinosis. Additionally, there is insertional intrasubstance tearing involving the posterior fibers of the supraspinatus tendon and perhaps anterior fibers of the infraspinatus tendon. This measures approximately 8 mm in the AP dimension and spans a majority of the width of the tendon but does not appear to disrupt the articular or bursal surface fibers. There is no atrophy of the supraspinatus or infraspinatus muscles. The teres minor and subscapularis muscles and tendons are intact.SUPRASPINATUS OUTLET: There is mild osteoarthritis of the acromioclavicular joint. We see no fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is normal. There is no joint effusion. There is detachment of the superior aspect of the anterior labor from the underlying glenoid which may represent variant anatomy rather than a tear. The inferior labrum is normal.BICEPS TENDON: The biceps tendon is intact.
