A case of prenatally detected hepatic cyst communicating with the hepatic duct

Abstract

Here, we describe the case of a 9-year-old girl. During the patient's prenatal period, her mother had suffered domestic violence perpetrated by the patient's father. On maternal ultrasonography and magnetic resonance imaging, an intraabdominal cystic lesion was detected in the fetus at around the 30th prenatal week. The patient was delivered normally, and there were no evident anomalies on her body. Computed tomography with drip infusion cholangiography and percutaneous retrograde transhepatic cholangiography demonstrated an intrahepatic cyst of approximately 3 cm in diameter, which was located at S5–S8 and communicated with the confluence of the bilateral hepatic ducts. The cyst is clinically conjectured to be a solitary intrahepatic biliary cyst. However, it remains possible that the cyst is a ciliated hepatic foregut cyst or indicates hepatic injury that may have occurred as a result of domestic violence to the mother. Careful, long-term observation of the patient will be continued to ensure that any malignant transformation is not missed.
