A solitary unilocular hepatic cyst (SUHC) is a rare prenatal or neonatal finding. There are few reports of the prenatal detection of SUHC, and the progression of SUHC in utero is unknown. We present a proven case of SUHC in a fetus detected on a 34-week ultrasound examination following a normal 19-week examination. The cyst was inseparable from the liver and caused some flattening of the liver edge. Prenatal detection of an SUHC inseparable from the liver and appearing in the late second or third trimester should suggest a congenital hepatic cyst.
