Cyst Size in Fetuses with Biliary Cystic Malformation: An Exploration of the Etiology of Congenital Biliary Dilatation

Abstract Purpose: Our aim was the longitudinal assessment of cyst size in fetuses with biliary cystic malformation (BCM) to explore its etiology and the possibility of antenatal differentiation between biliary atresia (BA) and congenital biliary dilatation (CBD). Methods: We conducted a retrospective review of all patients diagnosed antenatally with BCM from 1994 to 2014 at our institutions. Results: The study cohort comprised of three patients with BA and six with CBD. There were no significant differences in the gestational age
