Echogenic material in the fetal gallbladder in a surviving monochorionic twin.

Abstract

Fetal gallstones or echogenic sludge in the fetal gallbladder have rarely been reported prenatally despite the increasing number of ultrasound scans performed during pregnancy. In this report we present a case in which diffuse echogenic material was detected in the fetal gallbladder in a surviving monochorionic twin. This report identifies another predisposing factor for fetal gallstones/sludge in the perinatal period.
