66-year-old female with pain and restricted range of motion. Evaluate for rotator cuff tear. ROTATOR CUFF: There is a full-thickness tear of the supraspinatus at the level of its insertion on the greater tuberosity measuring approximately 10 mm in the AP dimension. There is minimal retraction of the proximal tendon. The tear extends posteriorly to involve the anterior fibers of the infraspinatus. There is minimal increased signal abnormality within the supraspinatus and infraspinatus muscles on fluid sensitive sequences suggesting that this tear may be acute/subacute in etiology. There is interstitial tearing of the supraspinatus and infraspinatus at the level of the myotendinous junction. The subscapularis and teres minor muscles and tendons appear intact.SUPRASPINATUS OUTLET: There is a small amount of fluid within the subacromial subdeltoid bursa. Mild to moderate degenerative changes affect the acromioclavicular joint with osteophyte formation along the inferior aspect of the distal clavicle and acromion process.GLENOHUMERAL JOINT AND GLENOID LABRUM: The glenohumeral joint alignment is anatomic. The glenoid labrum appears intact within the limitations of a non arthrogram study. There is a small amount of fluid within the glenohumeral joint which extends into the subscapular recess. Mild degenerative changes affect the glenohumeral joint.BICEPS TENDON: There is circumferential fluid within the tendon sheath of the long head of the biceps which likely represents fluid extension from the joint versus a very mild tenosynovitis.
