Pseudo-SLAP lesion

Pseudo-SLAP lesions represent a normal anatomic variant of the glenoid labrum that may simulate type II superior labral anterior posterior (SLAP) tears.

Gross anatomy

A synovial lined sulcus (or recess) may be located inferiorly to the long head of biceps tendon origin from the supraglenoid tubercle and superiorly to the posterosuperior aspect of the glenoid labrum. Its depth has been described as variable .

Radiographic features

MRI

On MR arthrograms, pseudo-SLAP lesions are best visualized on oblique coronal views as high signal intensity contrast material at the expected location. If deep enough, the sulcus may mimic a type II SLAP tear.
