摘要 目的:探讨足跟骨软骨母细胞瘤(Chondroblastoma,CB)的影像表现。材料与方法:回顾性分析经临床病理证实的12例足跟骨软骨母细胞瘤的X线、CT及MRI影像表现。结果:12例跟骨软骨母细胞瘤均表现为边界清晰、伴有硬化边、偏心性生长、膨胀感不明显的肿块;8例子X线可见片絮状钙化,7例CT可见砂砾状钙化,1例可见网格状分隔;3例CT表现为硬化边不完整,边缘毛刺;MRI示12例T1WI低于脂肪信号,稍高于肌肉信号伴硬化边明显,T2WI信号不均匀,坏死囊变呈高信号,钙化呈高信号。2例出现滑膜囊积液及骺软骨板增厚。结论:足跟骨软骨母细胞瘤影像学表现具有一定特征,结合X线、CT及MRI影像表现,有助于诊断及鉴别诊断。 Purpose: To study the Chondroblastoma of calcaneus (Chondroblastoma, CB) image performance. Materials and Methods: a retrospective analysis of 12 cases confirmed by clinical pathology of chondroblastoma of calcaneus of X-ray, CT and MRI images. Results: 12 cases with bone cartilage tumor are characterized by clear boundary, accompanied by hardening edge, partial mass mind growth, expand feeling is not obvious; 8 cases X ray visible flocculent calcification, 7 cases of CT shows gravel calcification, 1 case of visible fence separated ; 3 cases of CT performance for incomplete hardening edge, irregular edge; MRI shows 12 cases T1WI signal is lower than fat, shghtly higher than muscle signal with hardening of the edge, T2WI signal is uneven, show high signal, necrosis capsule calcification has high signal. 2 cases with effusion mem- brane sac and thickening of the epiphyseal cartilage plate. Conclusion: chondroblastoma of calcaneus imaging findings have certain characteristics, combined with X-ray, CT and MRI imaging performance, help to the diagnosis and differential diagnosis.
