Osteochondritis dissecans of the glenoid fossa

Case contributed by Dr Chris O'Donnell

Presentation

Ongoing shoulder pain post football injury some months ago.

Patient Data

Age: 25
Gender: Male

Large ovoid area of cortical bone loss involving the glenoid articular surface with minor residual fragmented bone.

Ovoid cortical defect filled a line of residual T2 hypointensity (presumed bone fragment) and T2 hyperintense material. Overlying articular cartilage seems in continuity apart from a small cleft close to midline (arrow on the axial image). No loose osteochondral body and only minor joint fluid. The patient also has AC arthropathy but no findings of instability.

Case Discussion

Glenoid OCD is rare, occurs most often as a result of acute trauma and has a high association with instability, labral tear, and intra-articular bodies.
