A 75-year-old woman was referred to our department for evaluation of a left renal tumor. Computed tomography and other imaging studies demonstrated a left renal mass and tumor extension into the left renal vein passing caudally behind the aorta. We clinically diagnosed the tumor as renal cell carcinoma (RCC) associated with a retroaortic left renal vein thrombus, and performed a radical nephrectomy. Pathological examination of the surgical specimen showed a grade 2, clear cell carcinoma with a renal vein thrombus and negative surgical margin. Retroaortic left renal vein is a rare anomaly with a prevalence of 1.8-2.4%. RCC associated with a retroaortic left renal vein thrombus is rarer still. To our knowledge, this is only the third case report to describe an RCC associated with a tumor thrombus in the retroaortic left renal vein.
一位 75 岁女性因左肾肿瘤就诊于我科。计算机断层扫描和其他影像学研究显示左肾有一肿块，肿瘤延伸至左肾静脉，在主动脉后方向后延伸。我们临床诊断为肾细胞癌（RCC）伴左肾静脉后主动脉瘤栓，行根治性肾切除术。手术标本的病理检查显示为 2 级透明细胞癌，伴有肾静脉血栓和阴性手术切缘。左肾静脉后主动脉瘤是一种罕见的异常，其发生率为 1.8-2.4%。伴左肾静脉后主动脉瘤栓的 RCC 更为罕见。据我们所知，这只是第三例描述伴左肾静脉后主动脉瘤栓的 RCC 的病例报告。
