Fig. 5. Moderate dysplasia of posteroinferior glenoid in 43-year-old man
with shoulder pain. T2-weighted axial image (TR/TE, 4,000/73.976) from MRI
arthrogram of shoulder shows posterior sloping of glenoid articular surface
and truncation of posteroinferior glenoid rim (arrow). There is
slight proliferation of abnormal low-signal soft tissue adjacent to bone
defect in posterior glenoid. This case is considered moderate because glenoid
rim truncation continued cephalad for several more sections without
reconstitution of posterior glenoid rim.
