50-year-old male with left shoulder pain x5 years, no improvement with multiple injections or physical therapy ROTATOR CUFF: There is no fluid signal traversing the supraspinatus tendon to indicate a full-thickness tear. However, there is intermediate signal intensity within and along the undersurface fibers of the distal supraspinatus tendon likely representing tendinosis along with undersurface fraying/tearing. Signal abnormality involves approximately 50% of the tendon thickness and measures 1 cm in long dimension and 1 cm in transverse dimension. Posteriorly, the tendon appears intact. The supraspinatus muscle appears normal. The infraspinatus, teres minor, and subscapularis muscles and tendons are within normal limits.SUPRASPINATUS OUTLET: The acromioclavicular joint appears normal for age although there is slight spurring of the anterior acromion. No fluid is noted within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral alignment is within normal limits. Given the limitations of a nonarthrographic study, no fluid filled labral tear is evident. A focus of intermediate signal intensity separating the superior labrum from the underlying glenoid could conceivably represent an underlying SLAP tear or a normal variant. BICEPS TENDON: The long head of the biceps tendon is intact. Small lobulated focus of fluid signal intensity along the extra-articular surface of the biceps tendon is likely of no current clinical significance. ADDITIONAL
1.Intermediate signal within and along the undersurface of the the distal supraspinatus tendon is suggestive of tendinosis and undersurface fraying/tearing. No fluid-filled full-thickness rotator cuff tear is seen. 2.Other findings as above.
