摘　　要：目的探讨软骨母细胞瘤(CB)的CT表现,观察CT对该病的诊断及鉴别诊断价值。方法对经手术病理证实的34例CB患者的CT资料进行回顾性分析,分析其病灶位置、形态、密度及增强表现等特征。结果 28例(82.35%)患者病灶位于长骨;19例(55.88%)病灶边缘可见硬化边;21例(61.76%)病灶内可见点状或沙粒状钙化;全部21例接受增强扫描者均表现为轻中度强化。结论 CB有较为典型的CT表现;CT对CB的诊断和鉴别诊断具有重要价值。Objective To investigate the characteristics of chondroblastoma（CB）on computed tomography（CT）,and to observe the value of CT in the diagnosis and differential diagnosis of CB.Methods CT images of 34 patients with pathologically confirmed CB were reviewed retrospectively.The location,shape,density and contrast enhancement features of the lesions were assessed.Results The lesions of 28（82.35%）patients located in long bones.Sclerotic edge was seen in 19（55.88%）patients.Sandy or spotty calcification in the focus was shown in 21（61.76%）patients.Slight or moderate enhancement was detected in all 21 patients who underwent contrast enhanced CT.Conclusion CT presentation of CB is typical.CT plays an important role in the diagnosis and differential diagnosis of CB.
