Fetal Gallstones

Gallstones and hepatic masses are in the differential diagnosis of echogenic foci in the right upper quadrant. Gallstones and sludge may be seen during the third trimester, and are thought to be caused by hemolytic disease, cholestasis, and maternal drug use. Fetal gallstones and sludge are not generally associated with postnatal complications, and most resolve by birth or soon thereafter.
