An anteroposterior radiograph of the right shoulder showed marked hypoplasia of the scapular neck and glenoid, which had a notched appearance, compatible with the radiographic findings seen with glenoid dysplasia (Fig 1).
55 year old male with glenoid dysplasia; MR arthrographic findings. (A) Axial T1 weighted fat-suppressed image from direct MR arthrogram of the right shoulder shows hypoplasia and retroversion of the glenoid with marked hyperplasia of the glenoid labrum. Contrast is seen to imbibe into the hyperplastic glenoid labrum (arrow), consistent with a labral tear.. (B) Axial T1 weighted fat-suppressed image from direct MR arthrogram of the right shoulder in ABER position shows hypoplasia of the glenoid and scapular neck (arrow). Note the markedly hyperplastic posterior glenoid labrum. [Powerpoint Slide]

An MR arthrogram of the right shoulder was subsequently performed and showed a markedly hypoplastic retroverted bony glenoid with a hyperplastic glenoid labrum (Figure 2, Figure 2).
55 year old male with glenoid dysplasia; MR arthrographic findings. (C) Coronal T1 weighted fat-suppressed image from direct MR arthrogram of the right shoulder shows characteristic notch in the glenoid (arrow), previously described on radiograph. Also note the enlarged and dysplastic superior glenoid labrum (arrowhead). [Powerpoint Slide]

The patient's symptoms failed to improve and an arthroscopic evaluation of the right shoulder was performed which showed a markedly hyperplastic glenoid labrum with associated labral fraying (Fig 3).
