Liver nodules resembling focal nodular hyperplasia after hepatic venous thrombosis

We report the case of focal nodular hyperplasia-like nodular hepatic lesions, that developed in the liver of a 35-year-old Caucasian female who required orthotopic liver transplantation for Budd-Chiari syndrome. The rapid development of focal nodular hyperplasia-like lesions in a severe hepatic vascular disorder and in the absence of cirrhosis may represent an additional argument in favor of the vascular origin of focal nodular hyperplasia. The pathogenesis of the nodules is not clear, but pathological arterialization of the liver in hepatic vein thrombosis may be a candidate mechanism.
