Fibropolycystic liver diseases are a group of congenital disorders with a common origin in ductal plate developmental abnormalities and varied fenotypes. They include the simple hepatic cysts, Caroli disease and syndrome, polycystic liver diseases, congenital hepatic fibrosis and biliary hamartomas. In this chapter, we first discuss the embryologic developent of the normal ductal plate and of the multiple ductal plate abnormalities.
