摘　　要：目的:探讨不同亚型乏血供肾癌的CT表现,提高对不同亚型乏血供肾癌的术前诊断准确性。方法:回顾性分析46个(45例)经病理证实的乏血供肾癌病灶的CT表现特征并与其病理结构对比分析,其中透明细胞肾癌(CCRCC)27个(26例),乳头状肾癌(PRCC)17个,肾嫌色细胞癌(CRCC)2个,对前两个亚型的CT表现进行统计学分析。结果:肾癌的CT表现与病理结构相关。透明细胞肾癌中形态不规则或边界不清楚、直径≤3cm及伴肾实质外侵犯者分别为17、11和15个,而乳头状肾癌中分别为5、2和4个,这3个征象在两种病变类型间的差异均有统计学意义(P<0.05),余CT表现在两亚型间差异无统计学意义。结论:CT在不同亚型乏血供肾癌的诊断及鉴别诊断中具有重要的应用价值。Objective：To investigate the CT findings of hypovascular renal cell carcinoma with different subtype,in order to improve the preoperative diagnostic accuracy. Methods： The CT manifestations of 45 patients with 46 pathology proven hypovascular renal cell carcinomas were retrospectively analyzed and correlated with pathologic structures. Of the 46 tumors, there were clear cell renal cell carcinoma （CCRCC, n= 27）, papillary renal cell carcinoma （PRCC, n= 13） and chro- mophobe renal cell carcinoma （CRCC, n= 2）. The CT features of the former two subtypes were statistically analyzed. Results：The CT features of different subtypes were correlated with pathologiy. Of CCRCC,there were irregular shaped or ill-defined （n= 17） ,with the diameter ≤3cm （n= 11） and extra-renal parenchymal invasion （n= 15） ; however, of PRC, which were 5,2 and 4 accordingly. These three CT features showed significant statistic differences between the two sub- types （P〈0.05）. While there were no significant statistic differences in the rest of CT findings between the above-men- tioned subtypes. Conclusion： CT scanning is important for the diagnosis and differential diagnosis of hypovascular renal cell car- cinoma with different subtype.
