Abstract:
Objective To analyze the imaging signs of chondromyxoid fibroma(CMF)and to improve the diagnostic accuracy of CMF.Methods The imaging data of 31 cases of CMF diagnosed by pathology were analyzed retrospectively and the characteristic imaging signs were analyzed.Results Among the 31 CMF patients,the male-to-female ratio was about 1.4∶1,and 75％of cases occurred before the age of 30;20 cases occurred in the long bones:15 cases in the tibia,4 cases in the femur,and 1 case in the fibula;15 cases occurred in the metaphyseal;7 cases occurred in the flat bones,and 4 cases occurred in the bones of the hands and feet.All lesions showed osteolysis with different degrees of expansion,lobulation,clear borders,and sclerotic margins on both X-ray plain film and CT.There was internal mineralization in 17 cases and internal bone ridge in 12 cases.All lesions showed T1 WI low-equal signal,T2WI medium-high signal in MRI,and enhanced scans were dominated by circumferential or nodular enhancement of the margins.Conclusion Multiple imaging examination methods can improve the diagnosis of CMF.
