Question: what are two key features to help differentiate between low and high grade chondrosarcoma?
Answer: Low-grade chondrosarcomas often show endosteal scalloping and a small degree of osteolysis. Intermediate and high-grade lesions demonstrate more aggressive radiographic features, such as osteolysis, medullary expansion, cortical thickening, cortical disruption, and the presence of a soft-tissue mass.
