Fetal ventriculomegaly

Hehong Li, Huiying Liang, Huiying Wu
The fetal ventriculomegaly development leads to neurological, motor, and/or cognitive impairment, and is presently diagnosed based on the width of the atrium in the lateral ventricle. But in this study, we have tried to assess the relationship between the development of calcarine sulcus and width of fetal lateral ventricles, to assess if calcarine sulcus can also be used for fetal ventriculomegaly diagnosis. We conducted a retrospective analysis of the magnetic resonance imaging (MRI) data from 45 subjects with isolated mild fetal ventriculomegaly (IMVM)...

Ventriculomegaly (VM) is a nonspecific finding on fetal imaging. Identification of the specific etiology is important as it affects prognosis and may even change the course of current or future pregnancies. In this review we will focus on the application of fetal MRI to demonstrate intracranial hemorrhage (ICH) and ischemic brain injury as opposed to other causes of VM. MRI is able to identify the specific etiology of ventriculomegaly with much more sensitivity and specificity than ultrasound and should be considered whenever VM is identified on obstetric ultrasound...

BACKGROUND: Magnetic resonance imaging (MRI) is gradually becoming more common for thorough visualization of the fetus than ultrasound (US), especially for neurological anomalies, which are the most common indications for fetal MRI and are a matter of concern for both families and society. OBJECTIVES: We investigated fetal MRIs carried out in our center for frequency of central nervous system anomalies. This is the first such report in southern Iran. MATERIALS AND METHODS: One hundred and seven (107) pregnant women with suspicious fetal anomalies in prenatal ultrasound entered a cross-sectional retrospective study from 2011 to 2013...

INTRODUCTION: the relevance of intrauterine infections is determined by significant peri- and postnatal loss as well as health impairment, which often results in disability and reduced quality of life. Ultrasonography is employed in order to provide a reliable assessment of the functional state of the fetoplacental system secondary to intrauterine fetal infection in the course of pregnancy. Ultrasound imaging is essential in diagnosis of various preclinical complications of pregnancy and detection of abnormalities in the developing fetus...

Recent data strongly suggest an association between the current outbreak of ZIKA virus (ZIKV) in many countries of Central and South America and a sharp increase in the detection of microcephaly and fetal malformations. The link with brain defect, which has been detected mainly in some areas of Brazil, is supported by the following evidence: (1) ZIKV transmission from infected pregnant women to their fetuses; (2) the potential of ZIKV to determine a specific congenital fetal syndrome characterized by abnormalities involving primarily the developing brain and eye...

INTRODUCTION: Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare condition that may lead to intracerebral haemorrhage (ICH) in the fetus or neonate. Platelet alloimmunisation causing FNAIT has been described in association with fetal cerebral ventriculomegaly (VM), presumably due to subclinical ICH. The objective of this study was to assess the association between fetal VM and platelet alloimmunisation. METHODS: This is a case series of pregnancies with fetal VM screened for platelet alloantibodies from 2003 to 2012...

OBJECTIVE: Vein of Galen aneurysmal malformation (VGAM) is a rare anomaly in which an adequate perinatal management may warrant good neurological outcome. However, most fetal series are too scant to allow reliable statistical assessment of poor prognostic factors. Aim of this paper is to assess, in a two-center series of 49 cases, the prognostic value of several prenatal variables. The primary endpoint of the analysis is to identify possible prenatal indicators of poor outcome, in terms of mortality and cerebral disabilities...

AIM: The prevalence of Down syndrome in infants with fetal ventriculomegaly is 5% to 10%; however, the converse, the prevalence of cerebral ventriculomegaly in live-born infants with Down syndrome, is not well established. Because cranial ultrasounds are performed on most very-low-birthweight (VLBW) infants (birthweight <1500g), our aim was to examine ultrasound abnormalities of VLBW infants to determine prevalence of ventriculomegaly and intraventricular hemorrhage (IVH) in VLBW infants with Down syndrome, and whether VLBW infants with Down syndrome are at higher risk for cranial ultrasound abnormalities, compared with the already elevated risk in other VLBW infants...
