PURPOSE: To investigate the prevalence of echogenicity in the fetal gallbladder (EFG) and to present prenatal sonographic findings and their postnatal outcomes.
MATERIALS AND METHODS: We performed a retrospective study within 17420 pregnant women during a 66-month period. Fetuses with an incidental finding of EFG in their 2nd or 3rd trimester of pregnancy were followed until birth per two weeks with sonographic examinations.
RESULTS: Out of 5977 fetuses, 44 fetuses were found to have EFG with a prevalence of 0.74%. Nine (20%) of 44 fetuses had single echogenicity, 25 (56%) had multiple echogenicities, 10 (22%) had sludge-like echogenicities. In Doppler sonography, 28 fetuses with EFG exhibited twinkling artifacts; however, none of the echogenicities had obvious acoustic shadowing. All of the cases were resolved either in utero or after birth before 10 months of age.
CONCLUSION: EFG is a late third-trimester phenomenon with a prevalence of 0.74%. Most EFGs presented as twinkling artifacts, suggesting they had a cholesterol component.
