Female, 52 years old. Pain. ROTATOR CUFF: There is a partial-thickness bursal surface tear of the posterior supraspinatus tendon near the myotendinous junction. The tear extends for approximately 6 mm in AP dimension and involves just over 50% of the tendon thickness, with less than 1 cm retraction of the torn fibers. There is also a very small partial-thickness articular surface tear of the supraspinatus tendon near its insertion. There is a background of mild to moderate supraspinatus tendinopathy. The supraspinatus muscle shows mild to moderate atrophy. There is mild infraspinatus tendinopathy. Otherwise, the infraspinatus and teres minor tendons and muscles are intact. There is mild subscapularis tendinopathy without discrete tear identified.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint with a focus of marrow signal abnormality at the base of the coracoid process with extension toward the superior glenoid and adjacent small cysts..GLENOHUMERAL JOINT AND GLENOID LABRUM: The labrum is suboptimally evaluated on nonarthrographic images, but there is abnormal signal and morphology of both the superior and inferior aspects of the labrum, compatible with degenerative tearing.BICEPS TENDON: The tendon of the long head of biceps is normal in position and morphology.
