“…In one paper, enlarged portal veins were recognized histopathologically in an adenomatous hyperplasia shown as high attenuation on CTAP 23 . Fujisawa et al 28 . reported that a histologically advanced HCC measuring 5 cm was demonstrated as a hypervascular lesion on percutaneous transhepatic portography.…”

Even though the incidence of hepatic nodular lesions demonstrated as high attenuating on CTAP is low, all but one lesion in the current series showed iso- or hypo-attenuation on CTHA and/or helical CT, suggesting the hemodynamics are reciprocal between CTAP and CTHA. One exceptional lesion that showed high attenuation on both CTAP and conventional CT was pathologically advanced HCC. Based on the follow-up study of two untreated patients, this kind of lesion with high attenuation on CTAP seems to grow slowly.
