Frontal
Lateral
Exophytic and cauliflower-like mass with dense osteoid matrix arising from the posterior lateral aspect of the distal femoral metaphysis. On the lateral view, a thin lucent line is noted separating the bulky mass from the adjacent cortex. The radiographic findings are highly suggestive of juxtacortical osteosarcoma; parosteal type. No pathological fracture seen.
