摘　　要：目的分析软骨黏液样纤维瘤(CMF)的影像学征象,提高对CMF的诊断准确性。方法回顾性分析31例经病理确诊的CMF患者的影像资料,分析特征性影像学征象。结果在31例CMF患者中,男女比例约为1.4︰1,75%的病例发生在30岁之前。20例发生在长骨,胫骨15例,股骨4例,腓骨1例;其中15例发生在干骺端;扁平骨7例,手足骨4例。所有病变在X线和CT检查均表现为溶骨性病变并伴有不同程度的膨胀、分叶、边界清楚、硬化边,17例病变内部出现矿化、12例内部出现骨嵴。所有病变在MRI均表现为T_(1)WI低至等信号,T_(2)WI中至高信号,信号混杂,增强扫描后以边缘环形或结节状强化为主。结论多种影像学检查方法有助于提高CMF的诊断。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 T_(1)WI low-equal signal,T_(2)WI 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.
