Radiologic Findings

Coronal oblique T1-weighted fat-saturated images from an MR arthrogram (Figs. 14A–14C) show curvilinear high signal within the superior labrum, coursing from the glenoid attachment in a posterolateral direction (black arrows). The superior sublabral recess (Fig. 14A, white arrow), a normal anatomic variant, is situated at the 12 o’clock position adjacent to the biceps anchor and follows the superior rim of the glenoid in a medial direction, more medially than the adjacent high signal labral tear.
