Congenital absence of the terminal portion of the portal vein with visceral venous return to the suprahepatic inferior vena cava, a rare malformation, was demonstrated in an 18‐year‐old Japanese woman. She had nodular hyperplasia in the liver and a non‐functioning pancreatic endocrine tumour. It is generally believed that reduction of portal venous flow causes atrophic changes and, subsequently, nodular hyperplasia occurs in a well‐perfused area in the liver. However, the liver was not perfused by the portal vein in this case. It is suggested that nodular hyperplasia can occur without portal blood flow.
