We report on a 58-year-old female patient with renal cell carcinoma simulating transitional cell carcinoma on computed tomography. The computed tomography scan showed an enhancing 2.5-cm left renal pelvic mass without renal parenchymal mass. Urinalysis revealed microscopic hematuria. Cystoscopy and urine cytology was negative for transitional cell carcinoma. Laparoscopic nephroureterectomy was done under the preoperative diagnosis of localized transitional cell carcinoma of the renal pelvis according to the computed tomography findings. The histologic result, however, was a clear cell renal cell carcinoma.
我们报告了一例 58 岁女性患者，其肾细胞癌在计算机断层扫描上模拟移行细胞癌。计算机断层扫描显示左肾盂有一个增强的 2.5 厘米肿块，没有肾实质肿块。尿分析显示镜下血尿。膀胱镜和尿液细胞学检查均为移行细胞癌阴性。根据计算机断层扫描结果，术前诊断为局限性肾盂移行细胞癌，行腹腔镜肾输尿管切除术。然而，组织学结果为透明细胞肾细胞癌。
