INTRODUCTION
We report here a case of RCC without preoperative tumor thrombus that had progressed to RCC with IVC tumor thrombus.
CASE PRESENTATION
A 75-year-old man was referred to our hospital. Contrast-enhanced CT showed a 50-mm mass in the right kidney with an indistinct border, contrast in the early phase and washout in the late phase. RARN was attempted for RCC. Intraoperatively, a tumor thrombus was unexpectedly observed. We converted to open surgery, and the right kidney and tumor thrombus were removed. Postoperative lymphorrhea was observed, but the patient recovered without any problems. Lung and bone metastases subsequently appeared, and the patient died 2 months later.
CONCLUSIONS
Surgeons should keep in mind that a tumor thrombus can grow rapidly before performing surgery for renal cell carcinoma.
引言
我们在此报告一例术前无肿瘤血栓的肾细胞癌进展为伴有下腔静脉肿瘤血栓的肾细胞癌病例。
病例介绍
一名75岁男性被转诊至我院。增强CT显示右肾有一个50毫米的肿块，边界不清，早期强化，晚期廓清。尝试对肾细胞癌进行机器人辅助肾部分切除术（RARN）。术中意外发现肿瘤血栓。我们转为开放手术，切除了右肾和肿瘤血栓。术后观察到淋巴漏，但患者顺利康复。随后出现肺和骨转移，患者在2个月后死亡。
结论
外科医生在对肾细胞癌进行手术前应牢记肿瘤血栓可能迅速生长。
