case_images: MRI was subsequently ordered. MRI showed a subchondral bone cyst at the glenoid fossa (Figure 1).
case_images: CT scan shows the location of the cyst.

case_images: The diagnostic arthroscopy revealed a loose body measuring about 1.0 cm x 1.0 cm, which was identified as a piece of cartilage detached from the defect area (Figure 3), and a defect over the glenoid fossa at the lower anterior quadrant measuring 1.0 cm x 1.0 cm (Figure 4).

case_images: The surgery was then converted to open surgery using the deltopectoral approach, and the cyst was curetted (Figure 5) and packed with an autologous bone graft (Figure 6) harvested from the left iliac crest.
case_images: The defect area filled with autologous bone graft.
