Ill-defined osteolytic lesion in the epiphysis and metaphysis of right distal femur with cortical destruction. (a) Focal bone destruction with osteolytic lesion at the metaphysis and epiphysis of the distal femur and irregular thinning and cortex destruction at the ossification centre of the epiphysis, with more in the medial aspect. Obvious synovial proliferation and soft tissue enhancement at the right knee joint was noted, with more in the posterior aspect of the intercondylar notch (b–e).
