Reason: cuff tear? History: pain ROTATOR CUFF: There is a full-thickness tear of the anterior fibers of the supraspinatus tendon at its insertion on the greater tuberosity with minimal (5 mm) retraction of the tendon. This tear measures approximately 1 cm in the AP dimension. There is intermediate signal intensity within the supraspinatus tendon more proximally and posteriorly, which indicates moderate tendinosis with fraying of both tendinous surfaces. A thin elongated collection of near fluid signal intensity extending along the myotendinous junction of the infraspinatus tendon indicates intrasubstance cyst formation with equivocal extension to the articular surface. There is mild fatty atrophy of the infraspinatus along the myotendinous junction. The teres minor muscle and tendon appear intact. There is thickening and increased signal intensity of the distal fibers of the subscapularis likely representing a combination of tendinosis and redundancy due to internal rotation of the humerus. There is mild fatty atrophy of the subscapularis along the myotendinous junction.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid within the subacromial bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthrosis affects the glenohumeral joint. There is minimal posterior translation of the humeral head relative to the center of the glenoid. There is a small amount of fluid within the joint and there is intermediate signal intensity within the anterior aspect of the joint that we suspect represents synovitis. Additional heterogeneous low signal intensity situated between the glenoid and undersurface of the subscapularis likely represents a combination of redundancy of the capsular structures and synovitis. The superior labrum is largely replaced with intermediate signal intensity reflecting degenerative tearing.BICEPS TENDON: The tendon of the long head of the biceps is perched along the lateral aspect of the lesser tuberosity and we cannot exclude the possibility of a pulley injury.
