[摘要] 目的 对囊性肾细胞癌的CT影像学表现进行分析。 方法 将2016年1月—2017年1月间在该院确诊并接受治疗的35例囊性肾细胞癌患者作为此次研究对象，均行CT检查，对其CT检查的过程与结果进行回顾，总结此疾病的CT影像学表现。 结果 35例患者中，45.7%为透明细胞癌，主要CT表现是低密度、不均匀强化，少数患者可见坏死区、出血性病灶；34.3%为乳头状癌，主要CT表现是低密度、不均匀强化；14.3%为嫌色细胞癌，主要CT表现是低密度、不均匀强化；5.7%为多房囊性肾细胞癌，主要CT表现是局部有壁结节出现、强化明显。 结论 CT在囊性肾细胞癌的诊断中有一定应用价值，但囊性肾细胞癌的CT影像学表现特异性不够明显，对于此病的具体分型，需依据病理诊断。

[Abstract] Objective To analyze the CT imaging manifestations of cystic renal cell carcinoma. Methods 35 cases of patients with cystic renal cell carcinoma diagnosed in our hospital from January 2016 to January 2017 were selected and the given the CT examination， and the CT examination course and results were reviewed and the CT imaging manifestations of diseases were summarized. Results Of 35 cases， 45.7% patients were with clear cell carcinoma， and the main CT manifestations were low density and uneven intensify， and few patients were with necrotic zone and hemorrhagic lesions， 34.3% patients were with papillocarcinoma， and the main CT manifestations were low density and uneven intensity， and 14.3% patients were with chromophobe cell tumor， and the main CT manifestations were low density and uneven intensity， and 5.7% patients were with multilocular cystic renal cell carcinoma， and the main CT manifestations were local mural nodules and obvious intensity. Conclusion CT has a certain application value in diagnosis of cystic renal cell carcinoma， but the specificity of CT imaging manifestations of cystic renal cell carcinoma is not obvious， and the specific classification of the disease needs the pathological diagnosis.

囊性肾细胞癌即影像学、病理诊断结果显示有囊性改变出现的肾癌，在原發性肾癌中约占85%，经常于40岁以上的人群中发生[1-2]。此病常见临床表现为肉眼尿血（无痛）、腰痛等，早期大多不可见以上症状，症状出现时大多已经处于中晚期，使治疗难度增大[3]。因此，对于此疾病，早期确诊，并进行明确的分型极为关键，直接决定着患者预后的改善程度[4]。近年来，该院将CT应用在此病的诊断中，该次研究对将2016年1月—2017年1月在该院接受治疗的35例患者的CT影像学检查过程与结果，现报道如下。
