64-year-old male with pain and crepitus. ROTATOR CUFF: There is a tear of the insertion of the rotator cuff involving the supraspinatus as well as anterior fibers of the infraspinatus with minimal (5 mm) of retraction. There is full-thickness involvement of the anterior infraspinatus/posterior supraspinatus, and there appears to be additional bursal surface tearing of the anterior fibers of the supraspinatus. Overall, we estimate the tear is approximately 1.5 cm in AP dimension. Mild tendinosis affects the retracted supraspinatus tendon. There is mild fatty atrophy along the myotendinous junction of the supraspinatus and infraspinatus tendons. The teres minor muscle and tendon appear intact. There is a tiny undersurface insertional tear of the subscapularis as well as additional undersurface fraying, but we see no full-thickness tear and the muscle appears normal.SUPRASPINATUS OUTLET: Mild to moderate osteoarthritis affects the acromioclavicular joint with small synovial cysts along the undersurface of the joint. There is a trace amount of fluid within the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: No joint effusion is evident. Mild osteoarthritis affects the glenohumeral joint. There is increased signal intensity within the anterior labrum likely reflecting degenerative tearing. There are small cysts within the anterior aspect of the humeral head.BICEPS TENDON: The tendon of long head of the biceps appears intact.ADDITIONAL
1. Full-thickness insertional tear of the supraspinatus/infraspinatus as described above with minimal retraction as well as undersurface fraying of the subscapularis with a tiny insertional undersurface tear.2. Mild to moderate osteoarthritis affects the acromioclavicular and glenohumeral joints as well as other findings as described above.
