There is a central intramedullary chondroid calcification (2.3 x 1.8 x 1.6 cm) with lobulated well-defined margin of the distal femoral diaphysis. No associated cortical destruction, endosteal scalloping, periosteal reaction, or adjacent soft tissue mass.
No other bone lesion or joint effusion.
Case Discussion
According to the patient, this lesion already visible on the radiographs taken 5 years earlier which favors an enchondroma (incidental finding in this case).
Unable to process the form. Check for errors and try again.
