Male, 18 years old. Recurrent dislocation ROTATOR CUFF: The rotator cuff tendons and muscles appear normal.SUPRASPINATUS OUTLET: The acromioclavicular joint appears normal. We see no fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: Glenohumeral joint alignment is normal. There is a Hill-Sachs deformity of the humeral head posteriorly. Evaluation of the labrum is limited due to lack of intra-articular contrast. Although we see no fluid signal intensity traversing the anterior inferior labrum, intermediate signal intensity separates the anterior inferior labrum from the underlying glenoid, likely representing sequela of a prior labral tear. Furthermore, the superior labrum appears detached from the underlying glenoid anteriorly and is associated with a paralabral cyst. The posterior labrum appears normal.BICEPS TENDON: The tendon of the long head of the biceps appears normal.
Findings indicating prior anterior dislocation, including Hill-Sachs deformity and findings suggestive of prior anterior inferior labral tearing. There also appears to be a superior labral tear. These findings can be better evaluated with MR arthrography if clinically indicated.
