Congenital hepatic cyst: Eleven case reports.

BACKGROUND: Liver cysts in infants are uncommon. With modern diagnostic imaging, we can achieve an early diagnosis of congenital hepatic cysts. Our purpose was to investigate the clinical features, surgical treatment methods and prognosis of infants with congenital hepatic cysts. Herein, we report a case series of congenital hepatic cysts. CASE SUMMARY: Eleven infants with hepatic cysts were retrospectively analysed. Ten of them had simple hepatic cysts, and a girl with a large hepatic mass was diagnosed with a solitary intrahepatic biliary cyst accompanied by a choledochal cyst. Among the ten simple hepatic cysts, eight were solitary and two were multiple. A total of 87.5% (7 of 8) of infants with solitary hepatic cysts were detected before delivery, and 86% (6 of 7) of those cysts were located in the right lobe of the liver. Surgical intervention was required for symptomatic hepatic cysts. Cyst resection or unroofing with fulguration of the cyst bed was employed. No recurrence of cysts was observed in these infants. CONCLUSION: Congenital hepatic cyst is a condition with a narrow differential diagnosis. Accurate diagnosis is essential for appropriate management. Unroofing is the favoured treatment in infants with symptomatic cysts. Most infants with congenital hepatic cysts have a good prognosis.
