Portal vein tumor thrombosis (PVTT) is an uncommon condition in which tumor cells expand into the vessels, causing blood clot formation in the portal vein. PVTT is mainly associated with hepatocellular carcinoma, leading to an unfavorable prognosis; however, it can also develop in patients with other cancer types. Herein, we report a case of metastatic renal cell carcinoma diagnosed by a blind liver biopsy in a patient with dynamic computed tomography-confirmed portal vein thrombosis and cholangiopathy. This case illustrates the importance of systematic surveillance with routine laboratory tests and contrast-enhanced imaging studies on patients with cancer to detect potential liver infiltration of metastatic cancer.
门静脉肿瘤血栓形成（PVTT）是一种罕见的病症，肿瘤细胞侵入血管，导致门静脉内形成血栓。PVTT主要与肝细胞癌相关，导致预后不良；然而，它也可发生于其他癌症类型的患者。在此，我们报告一例经动态计算机断层扫描确诊为门静脉血栓形成和胆管病的患者，通过盲法肝活检诊断为转移性肾细胞癌。该病例说明了对癌症患者进行常规实验室检查和对比增强成像研究以检测转移性癌症潜在肝浸润的系统监测的重要性。
