Fetal ventriculomegaly

Beth M Kline-Fath, Arnold C Merrow, Maria A Calvo-Garcia, Usha D Nagaraj, Howard M Saal
Fetal ventriculomegaly is a common referral for prenatal MRI, with possible etiologies being hydrocephalus and hydranencephaly. The underlying cause of hydranencephaly is unknown, but many have suggested that the characteristic supratentorial injury is related to idiopathic bilateral occlusions of the internal carotid arteries from an acquired or destructive event. Fowler syndrome is a rare genetic disorder that causes fetal akinesia and a proliferative vasculopathy that can result in an apparent hydranencephaly-hydrocephaly complex...

BACKGROUND AND PURPOSE: Congenital aqueductal stenosis is a common cause of prenatal ventriculomegaly. An accurate diagnosis provides prognostic information and may guide obstetric management. The purpose of this study was to identify specific anatomic findings on prenatal MR imaging that can be used as predictors of congenital aqueductal stenosis. MATERIALS AND METHODS: Prenatal and postnatal MRIs of fetuses referred to our institution for ventriculomegaly between June 2008 and August 2015 were reviewed...

OBJECTIVE: To quantify survival and neurodevelopmental outcome of fetuses with prenatally detected isolated severe bilateral ventriculomegaly form published literature. METHODS: Medline, Embase and the Cochrane Library were searched electronically. Only cases with prenatal diagnosis of apparently isolated severe ventriculomegaly and postnatal neurodevelopment assessment were selected and included. Severe ventriculomegaly was defined by the authors as enlargement of the ventricular atria, with a diameter greater than 15 mm on the transventricular plane while all cases where the investigators were unable to detect associated structural abnormality, chromosomal abnormality or fetal infections, and regarded the ventriculomegaly to be apparently isolated were included...

OBJECTIVE: To present a case with prenatal diagnosis and cytogenetic characterization of 1p36 deletion syndrome whose first trimester combined testing is abnormal but a normal NIPT result. CASE REPORT: A 33-year-old had an abnormal 1st trimester fetal aneuploidy screening result, but no trisomies 13, 18, 21 were detected by the noninvasive prenatal testing. Amniocentesis was performed after ultrasound showed fetal ventriculomegaly and echogenic bowel. The final conventional cytogenetics revealed a karyotype of 46, XX, del(1)(p36)...

OBJECTIVE: The sonologist detects a so-called "soft marker" during approximately 10% of routine second-trimester anatomy examinations and is often uncertain about what further management is appropriate. This article will specifically address the management of patients with sonographic markers for six common entities: choroid plexus cysts (CPCs), ventriculomegaly (VM), echogenic intracardiac focus (EIF), urinary tract dilation (UTD), fetal echogenic bowel (FEB), and femoral and humeral shortening...

PURPOSE OF REVIEW: Ventriculomegaly is one of the most common abnormal sonographic findings, which is associated with congenital infection, chromosomal and additional structural abnormalities. Currently, karyotype analysis is the primary method to detect chromosomal abnormalities in fetuses with ventriculomegaly. Recently, with the introduction of chromosomal microarray analysis (CMA) in prenatal diagnosis, copy number variations (CNVs) have been identified in cases of ventriculomegaly...

BACKGROUND: Congenital Zika virus (ZIKV) infection can be detected in both the presence and absence of microcephaly, and manifests as a number of signs and symptoms detected clinically and by neuroimaging. However, to date, qualitative and quantitative measures for the purpose of diagnosis and prognosis are limited. OBJECTIVES: Main objectives of this study conducted on fetuses and infants with confirmed congenital ZIKV infection and detected brain abnormalities are: 1) To assess the prevalence of microcephaly and the frequency of the anomalies including a detailed description based on ultrasound and magnetic resonance imaging (MRI) in fetuses and ultrasound, MRI and computed tomography imaging postnatally; 2) To provide quantitative measures of fetal and infant brain findings by MRI using volumetric analyses and diffusion weighted imaging (DWI); 3) To obtain additional information from placental and fetal histopathological assessments and postnatal clinical evaluations...

OBJECTIVES: Chromosomal microarray analysis is effectively applied prenatally to detect copy number changes. Single nucleotide polymorphism (SNP) probes included in the microarray platform can detect regions of excessive homozygosity and identical-by-descent genomic stretches. The utility of the latter as part of prenatal diagnosis is not well established. Recessive founder mutations are well recognized within distinct ethnic groups. Combining these data with prenatal sonography provides accurate focused molecular diagnoses quickly...

PURPOSE: Antenatally diagnosed ventriculomegaly (VM) requires the balance of risks of neurological injury with premature delivery. The purpose of this study was to evaluate outcomes related to early elective delivery due to fetal VM at our institution. METHODS: We retrospectively assessed 120 babies (2008-2012) with antenatally diagnosed fetal VM. Inclusion criteria for ("early") cohort were (1) elective delivery occurred for expedited neurosurgical intervention between 32 and 36 weeks EGA and (2) fetal VM noted on official antenatal ultrasound...

BACKGROUND: Zika virus (ZIKV) is a neurotropic and neurotoxic RNA Flavivirus prompt to cause severe fetal brain dysmorphisms during pregnancy, a period of rapid and critical central nervous system development. A wide range of clinico-radiological findings of congenital ZIKV infections were reported in the literature, such as microcephaly, overlapping sutures, cortical migrational and corpus callosum abnormalities, intracranial calcifications, ventriculomegaly, brain stem and cerebellar malformations, spinal cord involvement, and joint contractures...

BACKGROUND: A relationship between Zika virus (ZikV) infection in pregnancy and the occurrence of microcephaly was established during the Zika outbreak in Brazil (2015-2016). Neuropathological findings in congenital Zika syndrome helped to understand its pathogenetic mechanisms. RESULTS: The most relevant postmortem findings in the central nervous system (CNS) of fetuses and neonates infected with ZikV early in gestation are microcephaly with ex-vacuo ventriculomegaly and large head circumference associated with obstructive hydrocephalus due to severe midbrain and aqueduct distortion...

OBJECTIVE: The new epidemic of Zika virus infection raises grave concerns, especially with the increasingly-recognized link between emerging cases of microcephaly and this infectious disease. Besides small cranial dimensions, there are striking morphologic anomalies in the fetal brain. Key anomalies include cortical developmental malformations and a peculiar distribution of pathologic calcifications. These potentially indicate a new pattern of congenital central nervous system infection...

Accumulating studies indicate that the brain is a direct target of air pollution exposure during the fetal period. We have previously demonstrated that exposure to concentrated ambient particles (CAPs) during gestation produces ventriculomegaly, periventricular hypermyelination, and enlargement of the corpus callosum (CC) during postnatal development in mice. This study aimed to further characterize the cellular basis of the observed hypermyelination and determine if this outcome, among other effects, persisted as the brain matured...

Relatively few agents have been associated with congenital infections involving the brain. One such agent is the Zika virus, which has caused several outbreaks worldwide and has spread in the Americas since 2015. The Zika virus is an arbovirus transmitted by infected female mosquito vectors, such as the Aedes aegypti mosquito. This virus has been commonly associated with congenital infections of the central nervous system and has greatly increased the rates of microcephaly. Ultrasonography (US) remains the method of choice for fetal evaluation of congenital Zika virus infection...

Uteroplacental transmission of a primary herpes simplex virus (HSV) infection in pregnancy has been reported; however, HSV ventriculomegaly of the neonate has not been well documented in utero. We present a case of a 19-year-old woman who developed a primary HSV outbreak at 17 weeks of gestation and was treated with acyclovir. A congenital malformation scan at 18 weeks of gestation demonstrated no fetal abnormalities; however, an ultrasound at 33 weeks showed a new finding of ventriculomegaly. Additionally, hydrocephalus was confirmed with magnetic resonance imaging...
