Purpose or Case Report: Congenital portosystemic shunts represent a rare congenital malformation which diverts portal blood to the systemic circulatory system. These malformations can either be intrahepatic or extrahepatic. The intrahepatic portosystemic shunts have been classified into four types. Intrahepatic congenital portosystemic shunts demonstrates a persistent communication between the portal and hepatic venous structures, which were derived from the embryonic vitelline veins or between the vitelline and subcardinal veins. A ductus venosus, a normal structure in neonates, represents an intrahepatic congenital portosystemic shunt between the left portal vein and left hepatic vein. It typically closes between 2-17 days of postnatal life. In our institution, since April 2020, there have been five separate cases of intrahepatic congenital portosystemic shunts in newborns. We will review the imaging for each of these cases, as well as review the current literature and classification of portosystemic shunts.
