Abstract:
Objective To study imaging features of primary chondrosarcomas and the correlation with pathologic basis.Methods The imaging materials of primary chondrosarcoma in 21 cases were retrospectively analyzed and correlated with pathological results. Results In 21 cases,the pathologic classifications were as following:15 cases of conventional intramedullary,1 case mesenchymal,2 cases myxoid,1 case dedifferentiated and 2 cases with no subtypes.For 6 cases of conventional intramedullary in gradeⅠand 8 cases in gradeⅡ,bone destruction in varying degrees accompanied with soft tissue mass(n=1 1),regional thickening cortical bone (n=2),“ring-arc”like matrix mineralization(n=6),amorphous (n=3)were showed on X-ray study.CT were performed,in 6 cases in gradeⅠ,6 cases in gradeⅡ and 1 case in grade Ⅲ in which there were intraosseous calcification (n=12),regional thickening cortical bone (n=2)and periosteal new bone formation (n=1).Lesions appeared expansive or osteolytic bone destruction accompanied with soft tissue mass on CT and MRI srudy MRI were performed in 5 cases in gradeⅠ and lesions were heterogeneous high signal intensity on T2 WI with spot like and “ring-arc”like low signal intensity.Conclusion Pathologic classifications and grading of primary chondrosarcoma may be presumed with imaging features.Pathologic characteristic manifestions on MR are superior to that on CT and X-ray.
