Right shoulder pain ROTATOR CUFF: There is increased signal within the supraspinatus tendon indicating moderate tendinosis. There is also a more focal full-thickness tear of the anterior fibers of the supraspinatus at its insertion upon the greater tuberosity. The tear measures approximately 8 to 9 mm in the AP dimension and results in approximately 7 mm of retraction of the anterior fibers. There is mild fatty atrophy of the supraspinatus muscle along the myotendinous junction. The tendinosis of the supraspinatus tendon extends posteriorly to involve the anterior fibers of the infraspinatus tendon and there is suggestion of bursal surface fraying although no full-thickness infraspinatus tear is appreciated. There is also mild fatty atrophy along the myotendinous junction of the infraspinatus tendon. Small cysts are noted in the underlying greater tuberosity which are likely degenerative in nature. The teres minor muscle and tendon are normal. There appears to be tearing of the superficial fibers of the subscapularis tendon from its insertion on the humeral head although the deeper fibers appear intact. The subscapularis muscle is normal.SUPRASPINATUS OUTLET: Moderate osteoarthritis affects the acromioclavicular joint. There is a small amount of fluid within the subacromial subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Mild osteoarthritis affects the glenohumeral joint and there is a small of fluid within the joint. There is increased signal within the superior labrum likely representing degenerative tearing. There is a rounded contour to the anterior labrum which may be degenerative in etiology. Glenohumeral alignment is normal.BICEPS TENDON: The tendon of the long head of the biceps appears slightly subluxed medially, coursing along the torn superficial fibers of the subscapularis tendon.
1. Focal full-thickness tearing of the anterior fibers of the supraspinatus tendon with additional degenerative tendinopathy of the supraspinatus and infraspinatus tendons.2. Tearing of the superficial fibers of the subscapularis tendon with medial subluxation of the long head of the biceps tendon.3. Osteoarthritis and labral degeneration as described above.
