Congenital hepatic cyst is a rare hepatobiliary malformation that can present as an asymptomatic, unilocular, upper abdominal cystic mass in the fetus.
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.
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.
先天性肝囊肿是一种罕见的肝胆畸形，在胎儿中可表现为无症状的单房性上腹部囊性肿块。
我们报告两例先天性肝囊肿病例，均在妊娠25周和33周时通过产前超声确诊。产后通过腹部超声和放射影像学检查得以证实。尽管这两名婴儿均无症状，但由于两例囊肿均不断增大，故均进行了腹腔镜切除。切除标本的病理检查证实，一例为单纯囊肿，另一例为表皮样囊肿。
我们的病例以及文献中描述的病例表明，产前偶然发现先天性肝囊肿是有用的，尤其是在妊娠晚期。这样的诊断可以进行适当的围产期监测、选择分娩方式，并在需要时及时进行产后手术干预。
