Male, 71 years old. Shoulder pain, painful arc, decreased rom, weakness. ROTATOR CUFF: There is increased signal intensity within the anterior fibers of the supraspinatus tendon at its insertion indicating a tear. The tear appears to involve the bursal surface fibers extending across the majority of the thickness of the tendon but sparing the articular surface fibers. The tear is just under 1 cm in AP diameter, and there is no frank retraction of the tendon. More proximally, there appears to be undersurface fraying as well as tendinosis of the supraspinatus tendon. The supraspinatus muscle appears normal. There also appears to be undersurface fraying of the infraspinatus tendon with small cysts in the underlying humeral head but no full-thickness tear. The infraspinatus muscle appears normal. The teres minor tendon and muscle appear normal. There is mild subscapularis tendinosis but no discrete tear. The subscapularis muscle appears normal.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. We see no frank fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthritis affects the glenohumeral joint. There is a small amount of fluid in the joint, particularly in the subscapular recess containing small intermediate signal intensity foci indicating synovitis or debris. There is mild degeneration of the labrum with linear foci of intermediate signal intensity traversing the superior, anterior, and posterior labrum, likely representing degenerative tearing.BICEPS TENDON: Increased signal intensity within the tendon of the long head of the biceps at its transition from the rotator interval to the bicipital groove represents tendinosis.
1.Partial-thickness bursal surface tear of the anterior fibers of the supraspinatus tendon with additional rotator cuff tendinosis and fraying as described above.2.Osteoarthritis and other findings as described above.
