Multiphase helical CT and multiphase dynamic MR imaging represent advances in cross-sectional imaging that allow evaluation of the liver during arterial and portal venous phases of contrast enhancement. A recent article describes perfusion disorders of the liver as manifestations of increased attenuation [1]. However, abnormal communication between the hepatic arteries, portal veins, or hepatic veins have been described in relatively few reports. Although communication within the liver between the hepatic artery and portal vein has been reported, including transsinusoidal, transvasal, and transplexal routes, these vascular communications are typically small and below the threshold of visualization with cross-sectional imaging [2].
