Male, 29 years old. Evaluate glenoid labrum. History of recurrent left shoulder dislocation. ROTATOR CUFF: The tendons of the supraspinatus, infraspinatus, subscapularis and teres minor appear intact.SUPRASPINATUS OUTLET: The AC joint is normal. There is no fluid in the subacromial/subdeltoid bursa.GLENOHUMERAL JOINT AND GLENOID LABRUM: There is increased signal intensity within the anterior inferior labrum with ill-defined margins and medialization along the anterior inferior aspect of the glenoid. This is compatible with labral degeneration/tearing and an ALPSA-type lesion. There is also irregularity of the margin of the anterior superior labrum which represents additional degeneration/fraying. Gadolinium separates the superior labrum from the underlying glenoid. While the margins of the superior labrum are well-defined, the gadolinium-filled gap is slightly wider and extends slightly more posteriorly than a typical normal variant sublabral recess, and therefore may represent a SLAP tear. There is minimal posterior translation of the humeral head in relation to the central glenoid. The articular cartilage appears intact. There is flattening of the posterior aspect of the humeral head indicating a Hill-Sachs deformity.BICEPS TENDON: Tendon of the long head of the biceps appears intact. ADDITIONAL
1. Anterior inferior labral degeneration/tear with medialization of the labrum suggestive of an ALPSA-type lesion. 2. Degeneration of the anterior superior labrum and what we suspect is a SLAP tear.3. Hill-Sachs deformity and other findings as above.
