Reason: r/o tendon History: R pain with limited ROM ROTATOR CUFF: There is partial-thickness tearing of the anterior fibers of the articular surface of the infraspinatus at the level of its insertion on the greater tuberosity measuring approximately 4 mm in AP dimension. The infraspinatus muscle appears intact. There is thickening and intermediate signal intensity within the supraspinatus indicating moderate tendinosis. There is partial thickness tearing of the anterior fibers of the articular surface of the supraspinatus at the level of its insertion on the greater tuberosity measuring approximately 10 mm in the AP dimension and involving less than 50% of the tendon width. There is also interstitial tearing of the supraspinatus more proximally. There is no significant retraction. There is mild fatty infiltration along the myotendinous junction of the supraspinatus and infraspinatus muscles. Evaluation of the subscapularis is limited due to lack of external rotation, however the subscapularis appears grossly intact. The teres minor muscle and tendon appear intact.SUPRASPINATUS OUTLET: There is a trace amount of fluid within the subacromial subdeltoid bursa. Mild osteoarthritis affects the acromioclavicular joint.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 cyst formation within the greater tuberosity.BICEPS TENDON: The tendon of the long head of biceps appears intact. There is circumferential fluid within the tendon sheath which may represent fluid extension of the joint. ADDITIONAL
Partial thickness insertional tearing of the rotator cuff as described above. No evidence of a full-thickness rotator cuff tear or retraction. Rotator cuff tendinosis.
