These are four contrast-enhanced CT images obtained in the portal venous phase, showing several hepatic metastases. Of note, both the left and right lobes appear to be involved, with a metastasis in the caudate lobe, which is technically challenging to resect. The lesions in segment IV and the caudate lobe are partially confluent and sitting right at the hepatic venous confluence with the inferior vena cava. In addition to multiplicity involving segments that are difficult to resect, a vascular contact issue is also evident that will make these lesions extremely challenging to resect from a surgical perspective.
