目的：分析肾细胞癌的ＣＴ表现，探讨其诊断，分期及与肾盂癌的鉴别。方法：对３５例手术病理证实的肾癌行常规平扫及静脉闭注法增强ＣＴ，其中５例行动态ＣＴ扫描。观察其ＣＴ征象并分期。结果：典型肾癌表现为大小不等肾肿块，混杂密度占多数（１６例），含高密度成分１１例。增强后其实质及边缘不同程度一过性强化。少见有囊性、脂性和致密性肿块及全肾受累者。根据Ｒｏｂｓｏｎ分法，Ⅰ～Ⅳ期各有９、１２、７、７例。诊断正确率９１％。结论：依据典型表现可准确诊断及分期，邻近肾盂及广泛浸润者宜与肾盂癌鉴别。
Objective: To analyze the CT features of renal cell carcinoma, and to explore its diagnosis, staging, and identification of renal pelvis cancer. METHODS: Thirty-five cases of renal cell carcinoma confirmed by surgery and pathology underwent conventional plain scan and venous occlusive injection to enhance CT. Five of them underwent dynamic CT scan. Observe the CT signs and stage them. RESULTS: Typical renal cell carcinomas were characterized by renal masses of varying sizes, with mixed density accounting for the majority (16 cases) and high-density components in 11 cases. After the enhancement, the nature and edges of the enhancement are transiently enhanced. Rare cystic, fat and dense masses and whole kidney involvement. According to Robson’s method, there were 9, 12, 7 and 7 cases in stages I-IV. The diagnostic accuracy rate is 91%. Conclusion: According to the typical performance can be accurately diagnosed and staged, adjacent renal pelvis and extensive infiltration should distinguish with renal pelvis cancer.
