70-year-old female with osteoarthritis, can't raise arm. ROTATOR CUFF: There is intermediate signal intensity within the supraspinatus and infraspinatus indicating mild to moderate tendinosis. There is fluid signal intensity traversing the majority of the thickness of the rotator cuff at its insertion on the greater tuberosity involving the posterior fibers of the supraspinatus and anterior fibers of the infraspinatus. The tear does appear to disrupt the bursal surface fibers of the tendon, but we suspect the articular surface fibers are spared. This tear measures approximately 1 cm in the AP dimension. There is fatty infiltration along the myotendinous junction of the supraspinatus and infraspinatus, which otherwise appear normal for age. The teres minor and subscapularis muscles and tendons appear normal for age.SUPRASPINATUS OUTLET: There is a small amount of fluid within the subacromial/subdeltoid bursa. Mild to moderate osteoarthritis affects the acromioclavicular joint. GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is normal. There is intermediate signal intensity within the superior labrum likely representing degeneration/degenerative tearing. Otherwise the labrum appears normal within the limitations of a non arthrogram study.BICEPS TENDON: The tendon of the long head of the biceps appears intact.
1. Rotator cuff tendinosis and high-grade bursal surface tear of the supraspinatus/infraspinatus.2. Acromioclavicular joint osteoarthritis and other findings as described above.
