目的:探讨成软骨细胞瘤的影像学表现,提高影像学诊断和鉴别诊断水平。方法:回顾性分析经手术病理证实11例成软骨细胞瘤患者X线平片、CT及MRI影像资料。结果:X线平片及CT检查4例,确诊3例;X线及MRI检查2例,确诊1例;X线平片,CT及MRI检查5例,确诊4例。X线平片显示病灶呈类圆形分叶状骨质破坏区,边界清晰,5例病灶呈偏心膨胀性改变,4例病灶内有明显不规则钙化。CT扫描显示骨质破坏区边缘清晰,可见硬化边,内呈软组织密度影,8例病灶可见斑点状钙化,邻近关节积液3例。MRI检查显示T1WI等低信号、T2WI混杂较高信号。结论:成软骨细胞瘤影像学表现有一定特征性,X线平片、CT及MRI联合检查可作出正确诊断。
Objective: To investigate the imaging findings of chondroblastoma and to improve the diagnostic and differential diagnosis of imaging. Methods: The data of 11 cases of chondroblastoma confirmed by surgery and pathology were retrospectively analyzed. The data of X - ray, CT and MRI were analyzed. Results: 4 cases were diagnosed by X-ray and CT, 3 cases were diagnosed by X-ray and MRI, 1 case was diagnosed by X-ray and MRI, 5 cases by X-ray, CT and MRI. X-ray showed lesions were round lobulated bone destruction area, the boundary is clear, 5 cases of lesions showed eccentric expansion, 4 lesions were significantly irregular calcification. CT scan showed a clear edge of the bone destruction area, showing the hardened edge, showing soft tissue density, spot visible calcification in 8 cases, 3 cases of adjacent joint effusion. MRI examination showed low signal such as T1WI, T2WI mixed higher signal. Conclusion: The imaging findings of chondroblastoma have some characteristics. The combined diagnosis of X-ray, CT and MRI can make the correct diagnosis.
