Fetal gallstones: Antenatal detection and management

Fetal gallstones are a rare sonographic finding. We came across two cases of fetal gallstones detected in routine third trimester scan over a period of one year. Both cases were confirmed to have gallstones in postnatal scan and showed complete resolution of the gallstones at 35 and 45 days after birth. The presence of gallstones in the fetus does not alter the fetal prognosis or obstetrical management since complete resolution is seen in most of the cases in late third trimester or neonatal period which may be due to either spontaneous passage of gallstones during early neonatal period or dilution of cholesterol crystals with postnatal hydration.
