56-year-old male with shoulder pain. ROTATOR CUFF: There is mild increased signal intensity along the undersurface fibers of the supraspinatus tendon suggesting fraying, but we see no discrete tear. A tiny focus of increased signal intensity within the tendon at its insertion on the greater tuberosity may reflect focal insertional tendinosis. The infraspinatus tendon appears intact. The teres minor tendon appears intact. There is mild increased signal intensity along the undersurface of the subscapularis tendon near its insertion likely reflecting fraying. On the fat saturated T2-weighted sequences, there is mild increased signal intensity of the supraspinatus, teres minor and posterior deltoid muscles, which could reflect subacute atrophy. We see no masses in the quadrilateral space or suprascapular notch. The subscapularis muscle and infraspinatus muscle are within normal limits.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. We see no fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is within normal limits. There is no evidence of joint effusion. There is intermediate signal intensity within the superior labrum which likely represents degenerative tearing. There is attenuation of the anterior superior labrum which may represent extension of the degenerative tearing.BICEPS TENDON: The long head of the biceps tendon is within normal limits. ADDITIONAL
1. Mild increased signal intensity within the teres minor, posterior deltoid muscle, and to a lesser degree the supraspinatus muscle which may reflect subacute atrophy. We see no masses within the quadrilateral space or suprascapular notch.2. There is mild undersurface tendinosis/fraying of the supraspinatus and subscapularis tendon but no discrete rotator cuff tear.3. Osteoarthritis of the acromioclavicular joint.4. Findings suggestive of degenerative tearing of the superior labrum.5. Subcentimeter focus of signal abnormality in the scapular spine which is nonspecific.
