Abstract

BACKGROUND

Renal cell carcinoma (RCCs) is the most common malignancy of the kidney. When RCC progresses, it is known to form tumor thrombus in the renal vein and/or inferior vena cava. However, RCC does not normally form tumor thrombus in the ureter or renal pelvis.

CASE PRESENTATION

A 43-year-old man presented to our department for the treatment of a renal tumor with asymptomatic gross hematuria. In a dynamic CT study, contrast enhancement revealed a tumor suspected to be RCC, but atypical finding as a tumor thrombus that filled the renal pelvis and the whole ureter was also observed. Nephroureterectomy was performed, and the tumor was diagnosed histopathologically as RCC.

CONCLUSION

We report here a very rare case of RCC with a tumor thrombus in the whole ureter.

摘要

背景

肾细胞癌（RCC）是肾脏最常见的恶性肿瘤。当 RCC 进展时，已知会在肾静脉和/或下腔静脉中形成肿瘤血栓。然而，RCC 通常不会在输尿管或肾盂中形成肿瘤血栓。

病例介绍

一名 43 岁男性因无症状肉眼血尿就诊于我科，拟行肾肿瘤治疗。在动态 CT 研究中，对比增强显示疑似 RCC 的肿瘤，但也观察到不典型的表现，即充满肾盂和整个输尿管的肿瘤血栓。行肾输尿管切除术，肿瘤的组织病理学诊断为 RCC。

结论

我们在此报告一例非常罕见的 RCC 伴整个输尿管内肿瘤血栓形成的病例。
