Abstract

So many cases of hepatocellular carcinoma have been resulted intra- or extrahepatic recurrence soon following radical therapeutic procedure such as surgical resection or transcatheter arterial chemoembolization(TACE). Recently, the cause is considered to decreasing angiogenesis inhibitors by complete ablation of primary tumor with angiogenesis factor production. We have experienced one case of hepatocellular carcinomas showing double hypo- and hypervascular masses in the liver. While the hypervascular tumor is still growing, the hypovascular tumor may be statyed to tumor dormancy by intrinsic angiogenesis inhibitor. When original hypervascular tumor was ablated with TACE, another hypovascular tumor switched to hypervascular one appearing tumor feeder on angiography.
