OBJECTIVE Fetal ventriculomegaly (FV), or enlarged cerebral ventricles in utero, is defined in fetal studies as an atrial diameter (AD) greater than 10 mm. In postnatal studies, the frontooccipital horn ratio (FOHR) is commonly used as a proxy for ventricle size (VS); however, its role in FV has not been assessed. Using image analysis techniques to quantify VS on fetal MR images, authors of the present study examined correlations between linear measures (AD and FOHR) and VS in patients with FV. METHODS The authors performed a cross-sectional study using fetal MR images to measure AD in the axial plane at the level of the atria of the lateral ventricles and to calculate FOHR as the average of the frontal and occipital horn diameters divided by the biparietal distance...

OBJECTIVE: Pallister-Killian syndrome (PKS) is a rare, sporadic genetic disorder caused by mosaic tetrasomy of the short arm of chromosome 12 (12p). Clinically, PKS is characterized by several systemic abnormalities, such as intellectual impairment, hearing loss, epilepsy, hypotonia, craniofacial dysmorphism, pigmentary skin anomalies, epilepsy, and a variety of congenital malformations. Prenatally, PKS can be suspected in the presence of ultrasound anomalies: diaphragmatic hernia, rhizomelic micromelia, hydrops fetalis, fetal overweight, ventriculomegaly in the central nervous system, congenital heart defects, or absent visualization of the stomach...

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 non-specific finding on fetal imaging. Identification of the specific aetiology 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 haemorrhage and ischaemic brain injury as opposed to other causes of VM. MRI is able to identify the specific aetiology of VM with much more sensitivity and specificity than ultrasound and should be considered whenever VM is identified on obstetric ultrasound...

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...
