摘要
目的探讨软骨母细胞瘤的X线、CT和MRI表现以及病理学特点。方法回顾性分析12例经病理证实的软骨母细胞瘤的影像学资料,12例均行X线平片检查,其中8例经CT检查,7例经MRI检查。结果 12例中,10例X线平片示病灶边界清楚,周围可见硬化边,病灶内可见斑点状和斑片状钙化。8例CT均清楚显示病灶及硬化边,均可见斑点状和斑片状钙化,5例可见骨膜反应和软组织肿胀。7例MRI均清楚显示病灶边缘,T1WI低信号,T2WI混杂信号,4例可见骨髓水肿,7例均做增强扫描病灶呈明显强化。结论软骨母细胞瘤的X线、CT和MRI征象和病理学表现具有一定的特征性,综合分析X线、CT和MRI征象有助于正确诊断。
Objective To study X-ray,CT and MRI manifestations and pathological features of chondroblastoma.Methods Images of 12 caseswith chondroblastoma proved pathologically were retrospectively analyzed.X-ray plain film examination was performed to all cases.CT detection was performed to 8 cases,and MRI was performed to 7 cases.Results Among 12 cases,X-ray plain films of 10 cases showed well-defined lesions,sclerotic boundary in surroundings and stippled and patchy calcification in lesions.CT images showed lesions,sclerotic boundary and stippled and patchy calcification clearly in 8 cases and periosteal reaction and soft tissue swelling in 5 cases.MRI showed well-defined lesions,low signal on T1WI and slightly mixed signal on T2WI in 7 cases and bone marrow edema in 4 cases.Obvious enhancement was detected in 7 patients who underwent contrast enhanced MRI.Conclusion Chondroblastoma has certain characteristics in the X-ray,CT and MRI appearance and pathology manifestation.It is helpful to make correct diagnosis by analyzing X-ray,CT,MRI appearance comprehensively.
