Prenatal ultrasound, computed tomography, and postmortem aspect of a fetus with congenital Zika syndrome related to maternal prolonged viremia in patient (case no. 122) in a cohort study of pregnant women admitted to Centre Hospitalier de l’Ouest Guyanais, French Guiana, January 1–July 15, 2016. The mother had symptomatic acute Zika virus infection at 8 weeks’ gestation (and had ongoing viremia until birth of her stillborn child with signs of congenital Zika syndrome. Severe microcephaly, ventriculomegaly, and calcifications were detected by ultrasound at 13 weeks’ gestation. Overall, this fetus had arthrogryposis detected on 3-D ultrasound (A) and postmortem (B); severe bilateral microphthalmia (blue arrows) detected on 3-D ultrasound (C) and fetal computed tomography (D); microcephaly with atrophic cortex detected on ultrasound (E) showing a head circumference of 160 mm at 25 weeks’ gestation (−5 SDs); ventriculomegaly detected on ultrasound (E); brain calcifications (blue arrows) detected on ultrasound (F) and computed tomography (G); pontocerebellar hypoplasia (yellow arrows) detected on ultrasound (F); and corpus callosum dysgenesis (yellow arrows) detected on ultrasound (H).
