Abstract

Metastatic lesions in the liver derived from colorectal cancer rarely invade the portal vein macroscopically. Portal vein tumor thrombus is commonly associated with hepatocellular carcinoma. Colorectal liver metastases are usually accompanied by microscopic tumor invasion into the intrahepatic portal vein, and the incidence of macroscopic tumor thrombus in the trunk of the portal vein is rare. Here, we provide unique appearance of metastatic colorectal cancer. To the best of our knowledge, macroscopically, the right portal vein filled with the tumor thrombus without any tumor in liver parenchyma has been quite rare.

摘要

源自结直肠癌的肝脏转移瘤很少在宏观上侵犯门静脉。门静脉瘤栓通常与肝细胞癌相关。结直肠癌肝转移通常伴有肿瘤在肝内门静脉的微观侵犯，而门静脉主干出现宏观肿瘤栓子的情况很少见。在此，我们展示了转移性结直肠癌的独特表现。据我们所知，宏观上，右门静脉充满瘤栓而肝实质内无任何肿瘤的情况极为罕见。
