Imaging of fibropolycystic liver disease

Abstract

Fibropolycystic liver diseases (FLDs) make up a rare spectrum of heritable hepatobiliary diseases resulting from congenital ductal plate malformations (DPMs) due to the dysfunction of proteins expressed on the primary cilia of cholangiocytes. The embryonic development of the ductal plate is key to understanding this spectrum of diseases. In particular, DPMs can result in various degrees of intrahepatic duct involvement and a wide spectrum of cholangiopathies, including congenital hepatic fibrosis, Caroli disease, polycystic liver disease, and Von Meyenberg complexes. The most common clinical manifestations of FLDs are portal hypertension, cholestasis, cholangitis, and (in rare cases) cholangiocarcinoma. This article reviews recent updates in the pathophysiology, imaging, and clinical management of FLDs.
