X-ray
Frontal
Lateral
On the x-ray, there is evidence of a bony protrusion located at the metaphysis on the anteromedial side of the distal femur. The lesion is pedunculated, pushing the corresponding soft tissue outward. The cortex of the lesion is continuous with the cortex of the healthy bone, and the medullary cavity is continuous with that of the healthy bone. There is no calcification and no periosteal reaction.
