Congenital hepatic cyst: Prenatal and postnatal imaging findings.

Introduction: Congenital hepatic cyst is a rare hepatobiliary malformation that can present as an asymptomatic, unilocular, upper abdominal cystic mass in the fetus.

Cases: We report two cases of congenital hepatic cyst in which the diagnosis was made by prenatal ultrasound at 25 and 33 weeks' gestation. The diagnosis was confirmed postnatally by abdominal ultrasound and radiologic imaging studies.
