Reported is a fetal D andy– W alker malformation that was strongly suspected in the first trimester through measurement of the brainstem–vermis ( B ‐ V ) angle, which was found to be 119° on transvaginal ultrasound examination at 14 weeks and 2 days gestation. Definitive diagnosis of the D andy– W alker malformation was made by magnetic resonance imaging following stillbirth. Ultrasound measurement of the B ‐ V angle may be a useful index for prenatal diagnosis of D andy– W alker anomalies during early pregnancy.
