Left shoulder pain ROTATOR CUFF: There is a full thickness tear of the supraspinatus tendon from its attachment at the greater tuberosity. There is approximately 2 cm of proximal retraction of the tendon from its insertion. The tear involves the entire supraspinatus tendon and extends into the anterior fibers of the infraspinatus tendon. The retracted distal fibers of the supraspinatus tendon are tapered, likely reflecting underlying chronic attritional tearing. The supraspinatus muscle is within normal limits. Increased signal within the remaining distal infraspinatus tendon fibers likely reflects additional tendinosis and partial thickness tearing. There is mild atrophy of the infraspinatus muscle. A tiny focus of increased signal at the subscapularis tendon insertion may reflect a small insertional tear, however otherwise the tendon and muscle are unremarkable.SUPRASPINATUS OUTLET: Mild osteoarthritis affects the acromioclavicular joint. A small amount of fluid is present in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is normal. A small amount of fluid is present within the joint, without large effusion. Tiny glenohumeral joint osteophytes suggest minimal osteoarthritis. Increased signal intensity within the superior labrum reflects degeneration, without fluid filled tear seen. Small cysts are seen in the lateral humeral head, likely degenerative in etiology.BICEPS TENDON: There is thickening with increased signal intensity of the tendon of the long head of the biceps at its transition from the rotator interval to the intertubercular groove, indicating moderate tendinosis. A small amount of fluid around the tendon may reflect tenosynovitis or simply fluid extension from the glenohumeral joint.
