Bilateral pulmonary sequestration (PS) is a very rare congenital malformation. We describe a case of bilateral intralobar pulmonary sequestration (ILS) in a newborn. Both sequestrations received arterial supply from separate branches of the descending aorta and venous drainage was into ipsilateral inferior pulmonary veins. Prenatal ultrasonography showed cystic changes in the lungs. Computed tomography angiography (CTA) with supplemental two-dimensional (2D) and three-dimensional (3D) images was performed to clearly define the pathology and revealed bilateral intralobar pulmonary sequestration with aberrant blood supply...

Termination of pregnancy is indicated for Serratia marcescens bacteremia, a major cause of mortality. Our present case was highly challenging because the patient wished to continue with her pregnancy, and the ultrasonography showed features of a placental abscess. Although the outcomes were good after prolonged antibiotic treatment, this was an exceptional case.

Background: Early prediction of adverse neonatal outcome would be possible by Doppler impedance indices of middle cerebral artery (MCA), umbilical artery (UmA), and descending aortal artery (AO) that result in decrease neonatal morbidity and mortality rate. The aim of the present study was a determination of optimal value for the ratio of MCA to descending aorta blood flow (MCA/AO) impedance indices and its comparison with the ratio of MCA to UmA (MCA/UmA) impedance indices and their relationship with neonatal outcome...

Turner syndrome, characterized by the presence of a monosomy X cell line, is a common chromosomal disorder. Patients with Turner syndrome are usually phenotypically female, and male cases are rarely reported. Here, we report a fetus with a mosaic karyotype: mos 45,X/46,X,del(Y)(q11.21). The fetus was initially misdiagnosed as female with Turner syndrome by both noninvasive prenatal testing and cytogenetic analysis of amniotic fluid and was subsequently found to have male anatomy by antenatal ultrasonography at 24 weeks gestational age...

BACKGROUND: Health outcomes are improved when newborn babies with critical congenital heart defects (CCHDs) are detected before acute cardiovascular collapse. The main screening tests used to identify these babies include prenatal ultrasonography and postnatal clinical examination; however, even though both of these methods are available, a significant proportion of babies are still missed. Routine pulse oximetry has been reported as an additional screening test that can potentially improve detection of CCHD...

Total anomalous pulmonary venous return (TAPVR) is a rare congenital cardiac defect, accounting for 1.5-3% of cases of congenital heart disease. With prenatal ultrasonography, the majority of these patients are diagnosed in utero with definitive surgery performed during the neonatal period. However, as prenatal screening may not be available in developing countries, patients may present in later infancy. We present successful surgical repair of a 6-month-old infant with TAPVR who presented for medical care at 5 months of age in Lima, Peru...

Neurenteric cyst is a very rare developmental anomaly. Prenatal diagnosis of mediastinal neurenteric cysts has been reported rarely. We present a case of neurenteric cyst associated with vertebral anomalies diagnosed by prenatal ultrasonography at 31 weeks of gestation, which was treated successfully in the early neonatal period. In addition, we searched the English literature for all cases of mediastinal neurenteric cyst diagnosed in the prenatal period reported to date. We found that only 17 cases were reported previously...

This article reviews important features to improve the diagnosis of congenital heart disease (CHD) by applying ultrasound in prenatal cardiac screening. As low and high-risk pregnancies for CHD are subject to routine obstetric ultrasound, the diagnosis of structural heart defects represents a challenge that involves a team of specialists and subspecialists on fetal ultrasonography. In this review, the images highlight normal anatomy of the heart as well as pathologic cases consistent with cardiac malposition and isomerism, septal defects, pulmonary stenosis/atresia, aortic malformations, hypoplastic left ventricle, conotruncal anomalies, tricuspid dysplasia, and Ebstein's anomaly, and univentricular heart, among other congenital cardiovascular defects...

The benefit of the early administration of aspirin to reduce preterm pre-eclampsia among screened positive European women from multivariate algorithmic approach (ASPRE trial) has opened an intense debate on the feasibility of universal screening. This review aims to assess the new perspectives in the combined screening of pre-eclampsia in the first trimester of pregnancy and the chances for prevention using low-dose aspirin with special emphasis on the particularities of the Asian population. PubMed, CENTRAL and Embase databases were searched from inception until 15 November 2017 using combinations of the search terms: preeclampsia, Asian, prenatal screening, early prediction, ultrasonography, pregnancy, biomarker, mean arterial pressure, soluble fms-like tyrosine kinase-1, placental growth factor, pregnancy-associated plasma protein-A and pulsatility index...

Importance: The prevalence of autism spectrum disorder (ASD) has been increasing rapidly, with current estimates of 1 in 68 children affected. Simultaneously, use of prenatal ultrasonography has increased substantially, with limited investigation into its safety and effects on brain development. Animal studies have demonstrated that prenatal ultrasonography can adversely affect neuronal migration. Objective: To quantify prenatal ultrasound exposure by the frequency, timing, duration, and strength of ultrasonographic scans in children with later ASD, developmental delay, and typical development...

BACKGROUND: Malignancy during pregnancy has become a significant cause of maternal death in developed countries, likely due to both an older pregnant population, and increases of cervical cancer in younger women. Our aim is to investigate the clinical aspects of malignancy during pregnancy in Japan and to use this information to identify opportunities for earlier detection and treatment. METHODS: We provided a questionnaire to 1508 secondary or tertiary care hospitals in Japan...

BACKGROUND: Double gallbladder is a rare biliary anomaly. Perinatal diagnosis of the disorder has been reported in only 6 cases, and in 5 of them the diagnosis was based on ultrasound imaging only. However, the ultrasound technique alone does not provide a sufficiently precise description of cystic ducts and biliary anatomy, an information that is crucial for a correct classification and for a possible future surgery. CASE PRESENTATION: At 21 weeks of gestational age of an uneventful pregnancy in a 38 year old primipara mother, a routine ultrasound screening detected a biliary anomaly in the fetus suggestive of a double gallbladder...

BACKGROUND: Open neoureterocystostomy is the traditional surgical treatment for primary obstructive megaureter (POM). Endoscopic balloon dilation is a new minimally invasive alternative. It has been shown to be a safe and effective endoscopic procedure over short-term follow-up; however, few studies have shown its long-term efficacy. OBJECTIVE: The aim of this study was to evaluate the long-term results and complications of balloon dilation for the treatment of primary obstructive megaureter in infants...

Acute funisitis is characterized by the infiltration of fetal neutrophils from the umbilical vessels into Wharton's jelly and presents as fetal inflammation. However, no reports about its prenatal diagnosis using ultrasonography have been published. We encountered one case of oligohydramnios at 26 weeks and another case of threatened premature delivery at 27 weeks of gestation with ultrasonographic findings of non-uniform thickening of Wharton's jelly, a heterogeneous internal echo, and a high echoic line of the umbilical vessel wall...

INTRODUCTION: Joubert syndrome (JS) is a rare autosomal recessive inherited disease belonging to ciliopathy with the causative mutation of genes. Except for X-linked inheritance, the high recurrence rate of a family is about 25%. After birth, it may cause a series of neurological symptoms, even with retina, kidney, liver, and other organ abnormalities, which is defined as Joubert syndrome and related disorders (JSRD). Molecular genetics research contributes to disease prediction and genetic counseling...

OBJECTIVE: To assess the performance of non-invasive prenatal testing of achondroplasia using high-resolution melting (HRM) analysis. To propose an optimal diagnosis strategy combining ultrasound scan and cell-free fetal DNA (cffDNA) analysis. METHODS: Prospective multicenter study. CffDNA was extracted from maternal blood from women at risk for fetal achondroplasia (paternal achondroplasia, previous affected child or suspected rhizomelic shortening). The presence of one of the two main FGFR3 mutations was determined by HRM combined with confirmation by SNaPshot minisequencing...

Raine syndrome is a rare osteosclerotic bone dysplasia characterized by craniofacial anomalies and intracranial calcification. Most patients with Raine syndrome are of Arab ancestry and die during the neonatal period. We herein report a Japanese patient with non-lethal Raine syndrome who presented with characteristic cerebral hyperechogenicity and a hypoplastic nose by fetal ultrasonography. She was admitted to the NICU due to pyriform aperture stenosis. Craniofacial abnormalities, intracranial calcification, osteosclerosis, chondrodysplasia punctata, and a mutation of FAM20C was identified...
