目的 探讨肿瘤样钙质沉着症的影像及临床特点，旨在提高对该病的认识。方法 回顾性分析15例经手术病理证实肿 瘤样钙质沉着症患者的临床资料及影像表现进行分析与综合。结果 病变9例发生在髋部，X线及CT检查表现为软组 织内多发团块状高密度影，密度不均，边界清晰，部分融合，3例行MR检查，在T1WI上表现为低信号；T2WI上表现 为低信号团块影，其边缘及内部夹杂条索状高信号；增强扫描可见网格条索状的轻度不均匀强化。结论 肿瘤样钙 质沉着症临床及影像表现有一定特点，综合发病部位及影像表现，有助于该病的诊断及鉴别诊断。

Objective To explore the imaging and clinical features of Tumoral Calcinosis(TC),in order to improve the imaging diagnosis of this disease. Methods The clinical and radiographic data of 15 patients with pathologically confirmed TC were analyzed retrospectively. Results Most lesions occurred in hip, X - ray plain film and CT appeared as groups of high-density substance in soft tissue, inhomogeneous density and meromixis. 3 patients underwent MR, shown hypointense signal on T1WI and T2WI, hyperintense signal string around and in the lesions could been seen on T2WI. Both lesions appeared lightly nonuniform enhancement after administration of contrast medium. Conclusion The clinical and imaging of TC have some characteristics. Typical sites and imaging features are helpful for diagnosis and differential diagnosis of TC.
