History of rotator cuff tear now with shoulder pain, evaluate for recurrent tear. Foci of signal void within the soft tissues likely represent metallic susceptibility artifact from prior surgery. Similar foci within the humeral head presumably represent suture anchors.ROTATOR CUFF: There is a full-thickness tear of the supraspinatus tendon at the 12:00 position with delamination of fibers such that bursal surface fibers are retracted by approximately 1.5 cm and the articular surface fibers are retracted by approximately 2.5-3 cm. The tear measures just over 1 cm in the AP dimension. The retracted portions of the tendon appear thickened consistent with tendinosis. The more anterior fibers of the supraspinatus tendon appear to extend to the greater tuberosity. Mild fatty infiltration affects the myotendinous junction of the supraspinatus. The supraspinatus muscle otherwise appears normal. The aforementioned supraspinatus tear appears to extend posteriorly to involve the anterior fibers of the infraspinatus tendon. There also appears to be mild interstitial tearing of the infraspinatus tendon more proximally near the myotendinous junction. Mild fatty infiltration is present along the myotendinous junction of the infraspinatus. The infraspinatus muscle otherwise appears normal. The teres minor muscle and tendon are intact. The subscapularis muscle and tendon are intact.SUPRASPINATUS OUTLET: The acromioclavicular joint appears widened consistent with prior surgery. Bone marrow edema within the distal end of the clavicle is of uncertain etiology or significance, but we see no pronounced inflammatory changes to suggest infection. A small amount of fluid is present in the subacromial bursa which extends into but not beyond the acromioclavicular joint.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral alignment is within normal limits. A small amount of fluid is present within the glenohumeral joint without large effusion. Blunting of the superior labrum may be postoperative in etiology. The inferior labrum appears intact.BICEPS TENDON: The long head of the biceps tendon is not seen at the level of the rotator interval or within the proximal intertubercular groove. What we presume to be the biceps tendon is seen more distally, and these findings may reflect biceps tenotomy.ADDITIONAL
Recurrent rotator cuff tear and postoperative changes as other findings as described above.
