目的探讨CT与MRI对骨巨细胞瘤继发动脉瘤样骨囊肿的诊断价值.方法对43例经病理证实的骨巨细胞瘤继发动脉瘤样骨囊肿的CT及MRI资料进行回顾性分析.其中12例行CT检查,22例行MRI检查,另有9例同时行CT及MRI检查.结果 CT表现有18例呈偏心性改变,19例呈膨胀性改变,17例边缘呈分叶状改变,17例病灶内可见分隔或骨嵴.有4例突破骨皮质.有3例可见液-液平面.MRI表现有27例呈偏心性生长,28例呈膨胀性改变,26例边缘呈分叶状改变,继发的动脉瘤样骨囊肿主体在T1WI上呈低或中高信号,在T2WI上呈不均匀高信号,其中27例内可见分隔,8例可以看到液-液平面.结论 CT与MRI对骨巨细胞瘤继发动脉样骨囊肿诊断有重要价值,尤以MRI价值更大.

Objective To discuss the diagnostic value of CT and MRI in secondary aneurysmal bone cyst to giant cell tumor.Methods We collected 43 cases of secondary aneurysmal bone cyst to giant cell tumor and reviewed CT and MRI findings.Among the 43 cases patients,12 cases were imaged with CT scanning,22 cases with MRI imaging,9 cases with both CT scanning and MRI imaging.Results On CT,18 cases showed eccentricity,19 cases showed expansivity,17 cases showed sublobe margin,17 cases showed septations or cristae in the lesions,4 cases showed the lesions breakthroughed cortical bones,3 cases showed fluid-fluid level.On MRI,27 cases showed eccentricity,28 cases showed expansivity,26 cases showed sublobe margin,secondary aneurysmal bone cyst showed low or slightly high signal on T1WI,uneven high signal on T2WI.27 cases showed septations or cristae in the lesions,8 cases showed fluid-fluid level.Conclusions CT and MRI are very valuable in diagnosis of secondary aneurysmal bone cyst to giant cell tumor,especially on MRI.
