During follow-up ultrasonography (US) of metastatic liver tumors, a process of organization of intrahepatic portal vein thrombosis could be observed. Medical imagings, especially of a follow-up US of the intrahepatic portal vein thrombosis are herein reported. On June 1990 an extended cholecystectomy was performed on a 71-year-old female to treat cancer of the gallbladder. During the follow-up observation, metastatic liver tumors were detected and the Glisson's capsule of the posterior superior subsegment of the liver (G7) appeared as high-echo solid trabecular pattern in a US. A follow-up US revealed that the G7 changed from a high echo level to an iso-echo level. In January 1991, a subsegmental hepatectomy to remove metastatic liver tumors was carried out. Metastatic adenocarcinoma and an organized thrombus in the G7 was histologically demonstrated.
