61-year-old female with right shoulder pain. Evaluate for rotator cuff issues. ROTATOR CUFF: There is thickening and increased signal abnormality within the supraspinatus tendon consistent with moderate tendinosis. There is partial-thickness bursal surface tearing of the supraspinatus at the level of its myotendinous junction involving less than one half of the tendon fibers. There is increased edema type signal abnormality affecting the muscle belly of the infraspinatus. There is also marked fatty atrophy of the infraspinatus muscle. The infraspinatus tendon appears intact. The subscapularis and teres minor tendons and muscles appear intact.SUPRASPINATUS OUTLET: Mild to moderate degenerative changes affect the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Although this examination was not protocoled for evaluation of the glenoid labrum, no discrete labral tear is evident. There is a large glenohumeral joint effusion. Degenerative changes affect the glenohumeral joint. Note is made of multiple subchondral cysts within the humeral head.BICEPS TENDON: There is a large amount of circumferential fluid within the tendon sheath the long head of the biceps tendon which likely represents extension of fluid from the glenohumeral joint versus tenosynovitis. ADDITIONAL
1. Large glenohumeral joint effusion. Partial-thickness bursal surface tearing of the supraspinatus without evidence of a full-thickness rotator cuff tear.2. Edema type signal abnormality and fatty atrophy of the infraspinatus tendon raises the question of a denervation injury. No masses are identified within the spinoglenoid or suprascapular notches. Parsonage-Turner syndrome is also a differential consideration. 3. Findings suggestive of adhesive capsulitis/frozen shoulder. Other findings as described above.
