Abstract
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. Although the infants remained asymptomatic, laparoscopic excision was performed due to the increasing size of the cyst in both cases. Pathological examination of the resected specimens confirmed a simple cyst in one case and an epidermoid cyst in the other.
Conclusions
Our cases and those described in the literature demonstrate the usefulness of incidental prenatal detection of congenital hepatic cyst, especially during late pregnancy. Such a diagnosis can allow for proper perinatal surveillance, selection of the route of delivery, and timely postnatal surgical intervention if required.
