60 year-old female. Pain posterior shoulder, at times sense of popping and pain for 24 hours. ROTATOR CUFF: We see no full thickness rotator cuff tear. There is increased signal intensity within the distal fibers of the supraspinatus tendon at the 12 o'clock position, which may reflect tendinosis and perhaps partial thickness attritional thinning. There are also small cysts in the underlying humeral head. The supraspinatus muscle is within normal limits. Mild increased signal intensity within the distal subscapularis tendon is suggestive of mild tendinosis. The infraspinatus and teres minor tendons and muscles are intact.SUPRASPINATUS OUTLET: The acromioclavicular joint appears slightly widened with fluid in the joint, the clinical significance of which is uncertain but could be from old trauma or simply normal variation for this patient. There is a osteophyte projecting from the inferior aspect of the distal clavicle resulting in mild impression on the superior fibers of the supraspinatus muscle. There is a small amount of fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is normal. There is no joint effusion. Mild increased signal intensity within the anterior superior labrum may reflect degeneration but we see no fluid-filled tear. The articular cartilage of the shoulder appears normal.BICEPS TENDON: Given the limitation of a non-arthrogram exam, the tendon of the long head of the biceps is unremarkable.
1. Findings suggestive of mild tendinosis and possibly mild focal attritional thinning of the distal supraspinatus tendon. We see no fluid filled discrete rotator cuff tear.2. Slight widening of the acromioclavicular joint, which may reflect old trauma or simply normal anatomic variation for this patient. There is a distal clavicular osteophyte that results in mild impression of the superior fibers of the supraspinatus muscle. A small amount of fluid in the subacromial/subdeltoid bursa may reflect a mild bursitis.3. Other findings as above.
