Sonographic Detection of Seizure-Like Activity in Fetuses with Congenital Infection: Report of Three Cases and Review of the Literature.

Fetal seizure is a very rare prenatal finding and associated with an almost invariably poor outcome, the most common causes being hypoxic-ischemic encephalopathy, congenital anomalies of either the central nervous system (CNS) or musculoskeletal system, and metabolic disorders. The prenatal detection of seizure-like activity in fetuses with congenital infection has not been previously reported. In this report, we describe 3 cases of seizures in fetuses with congenital infection including Zika virus (n = 2) and toxoplasmosis (n = 1).

Splenic cyst as a rare cause of fetal abdominal cystic mass: A multicenter series of nine cases and review of the literature.

Introduction: Congenital splenic cysts are a rare cause of abdominal cystic masses in the fetus. We describe nine cases of this condition, the largest reported experience to date. A review of the literature for similar cases was also performed.

New Insights into the Natural History of Congenital Zika Virus Syndrome.

We describe the prenatal evolution of the brain findings in a patient with proved Zika virus infection at 8 weeks of gestation showing the very early appearance at 17 weeks of ventriculomegaly and signs of brain parenchymal involvement without microcephaly. The involvement of the brain becomes more evident at 22 and 27 weeks with the apparition of calcifications and microcephaly. Interestingly, the postnatal findings failed to show significant worsening when compared to these prenatal findings.

Thrombosis of the torcular herophili in the fetus: a series of eight cases.

Objective: The objective of this study was to describe the prenatal sonographic and magnetic resonance imaging (MRI) findings, antenatal course, and pregnancy outcome in fetuses diagnosed as having thrombosis of the torcular herophili.

Methods: Retrospective review of cases collected from five fetal medicine referral centers.

Results: Eight cases that were prenatally diagnosed by ultrasound between 22 and 32 weeks of gestation were reviewed.
