Abstract

This paper aims to compare the CT imaging features of osteosarcoma and chondrosarcoma based on pathology evidence. 27 patients with osteosarcoma or chondrosarcoma confirmed by surgical pathology in our hospital from October 2018 to February 2023 were retrospectively selected. Among them, 15 cases of osteosarcoma and 12 cases of chondrosarcoma underwent conventional CT scanning. The CT findings and diagnostic efficacy of each measurement parameter of the two types of patients were compared. Compared with osteosarcoma, the incidence of chondrosarcoma was significantly increased (P<0.05). Of the 15 cases of osteosarcoma, 9 cases (60.00%) developed in the long tubular bone. Of the 12 cases of chondrosarcoma, 7 cases (58.33%) occurred in axial bone, and the difference between them was significant (P<0.05). The appearance of periosteal reactions, Codman's triangle, and radial bone needles indicates a higher incidence of osteosarcoma, while the appearance of type IV calcium density shadow indicates a higher incidence of chondrosarcoma.
