Abstract:
Objective To investigate the imaging differentiation between high-grade and low-grade limb of long bone chon-drosarcoma.Methods The MRI imaging features in 23 cases of pathologically proven limb long bone chondrosarcomas were retro-spectively analyzed,including 13 cases of low-grade and 10 cases of high-grade.The MRI imaging features including endosteal scal-loping lesion,cortical thickening,cortical destruction,bone expansion,soft tissue mass,bone marrow edema,soft tissue edema,calci-fication,hemorrhage,tumour maximal radial line and enhancing features were performed the statistical analysis.Results 13 cases were the low-grade chondrosarcomas,including atypical cartilaginous tumour and grade 1 chondrosarcomas,10 cases were high-grade chondrosarcomas (8 cases of grade Ⅱ chondrosarcomas,1 case of gradeⅢ chondrosarcomas and 1 case of dedifferentiated chondrosarcomas).Cortical destruction,soft tissue mass and soft tissue oedema had statistical differences between the low-grade and high-grade.Bone marrow had statistically significant difference.Calcification +(SC<1/3ST)had statistical difference between the low-grade and the high-grade.Calcification ++(1/3 ST
