摘要
目的分析。肾透明细胞癌的CT影像特点。方法回顾性分析经病理证实的。肾透明细胞癌16例，从病灶数目、大小、形态、强化方式及与邻近结构关系等方面总结其CT影像特点。结果本组16例均为单发病灶，多位于肾皮质，形态多为圆形或类圆形，多凸出肾轮廓之外，平均4．7cm（2．2～10cm不等），伴或不伴邻近结构受累；增强扫描大多数（12例）动脉期明显不均质强化，静脉期及分泌期强化程度降低，低于周围。肾实质，即典型的“快进快出”式强化，1例动脉期中等度强化，2例仅轻度强化，1例肿瘤内形成动静脉瘘。本组病例其中1例为囊性肾透明细胞癌，内可见多发点状及条状钙化，增强后呈中等强化，囊内容物不强化。结论CT扫描是肾透明细胞癌的重要检查手段，其较特征性的动脉期强化方式是与其它类型肾癌相鉴别的重要参考依据。
Objective To analyse and summary the Computed Tomography（CT）imaging features of renal clear cell carci- noma（RCC）. Methods A retrospective analysis of 16 cases were proceeded, which had all been pathologically confirmed to be RCCC, interms of the lesion number, size, shape, manner, enhancement, and other metastasis. Results All cases were single lesion, located in the renal cortex, round or oval, mostly protruding the renal contour, average diameter of 4.7 cm （ranging from 2.2- 10. 0 cm）, with or without the involvement of the adjacent structures. The enhanced scanning showed significant, inhomogeneous enhancement in arterial phase, reduced enhancement in venous and secretory phase. However, one case had moderate enhancement and 2 cases had only slight enhancement in the artery phase. In one case, arteriovenous fistulae was found. Among all cases, there was a cystic RCCC, in which we can see multiple punctate and strip calcification, and moderate inhomogeneous enhancement. Conclusion CT is an important examination method of re- nal cell carcinoma, and its characteristic enhancement pattern in arterial phase is an important reference for identification with other types of renal cancer.
