OBJECTIVE: The records of 10 patients with focal nodular hyperplasia inducing intrahepatic vein obstruction were reviewed. The purpose of this study was to describe and emphasize the imaging features of these findings. CONCLUSION: Focal nodular hyperplasia may be responsible for hepatic vein obstruction with hepatic vein collaterals. The relatively large size and central location of the lesions seem to play important roles in the obstruction of the hepatic veins.
