title: CT demonstration of portal vein remnant within metastatic liver tumor.
abstract: We describe a patient with a metastatic liver tumor that showed a cordlike shadow traversing the tumor on CT. Histopathologically, this cordlike shadow within the metastatic liver tumor was proved to be an infiltrated portal vein without blood flow surrounded by fibrous tissue. Vascular structures traversing a focal lesion may be seen not only in focal fatty infiltration or lymphoma but also in metastatic liver tumor.
