Liver nodules resembling focal nodular hyperplasia after hepatic venous thrombosis

We report the case of focal nodular hyperplasia-like nodular hepatic lesion s, that developed in the liver of a 35-year-old Caucasian female who requir ed orthotopic liver transplantation for Budd-Chiari syndrome. The rapid dev elopment of focal nodular hyperplasia-like lesions in a severe hepatic vasc ular disorder and in the absence of cirrhosis may represent an additional a rgument in favor of the vascular origin of focal nodular hyperplasia. The p athogenesis of the nodules is not clear, but pathological arterialization o f the liver in hepatic vein thrombosis may be a candidate mechanism.
