Umbilical cord cysts (UCC) are a rare congenital malformation. Previous reports have suggested that the second- and third-trimester UCC may be associated with other structural anomalies or chromosomal abnormalities. Therefore, high-quality imaging is clinically important for the antenatal diagnosis of UCC and to conduct a precise anatomical survey of intrauterine abnormalities. There have been few reports of antenatal diagnosis of UCC with the conventional two- and three-dimensional ultrasonography. In this report, we demonstrate the novel visual depiction of UCC in utero with three-dimensional HDlive imaging, which helps substantially with prenatal diagnosis...

Pentalogy of Cantrell (PC) is a congenital anomaly characterized by a defect in the lower sternum, anterior diaphragm, and anterior abdominal wall; ectopia cordis; and congenital heart disease. It is a very rare congenital anomaly and the prenatal diagnosis is possible in the beginning of second trimester of pregnancy using the conventional ultrasonography. The prognosis is poor with high rates of perinatal mortality. We present a case report of prenatal diagnosis of PC at 22 weeks and 3 days of gestation. We emphasize the prenatal care follow up in a tertiary reference center, the parental counseling, the planning of delivery, and the management of newborn by a multidisciplinary team, including the description of immediate postnatal surgical repair...

The patient was a male infant with an antenatal diagnosis of huge intraabdominal mass. Prenatal ultrasound at 35 weeks gestation revealed a markedly enlarged cystic mass in the lower abdomen. After birth at 38 weeks, the infant was allowed to void spontaneously and passed meconium. Ultrasonography showed an enlarged bladder with wall thickness of 2.9 mm and no hydronephrosis. Voiding cystourethrograms showed no evidence of vesicoureteral reflex and posterior urethral valve. The post-void residuals were 15 mL at 11 days of life, 5 mL at 1 month and 0 mL at 5 months...

Dural sinus malformation (DSM) is a rare paediatric vascular malformation characterised by abnormal dilation of the posterior dural sinus. Owing to its rarity, the pathophysiology of DSM has not been fully elucidated. We report a case of prenatally diagnosed DSM with an unusual clinical course. We detected DSM in a male foetus in the 26th week of gestation by using foetal ultrasonography. Although the DSM regressed during the foetal stage and the arteriovenous shunt was insignificant in the neonate, the shunt rapidly developed four months after birth...

Our previous study confirmed the negative association between the development of calcarine sulcus and the width of lateral ventricles. The purpose of current study was to evaluate the reliability of calcarine sulcus depth in the 2nd trimester to predict the prenatal enlargement of lateral ventricle in fetuses with isolated mild fetal ventriculomegaly (IMVM).This study used a retrospective cohort study design. A total of 97 pregnant women with IMVM diagnosed between 20 and 26 weeks' gestation returned for a 2nd examination at 30 to 32 weeks...

OBJECTIVES: To describe the prenatal imaging findings in pontine tegmental cap dysplasia (PTCD), a rare congenital malformation of the hindbrain so far reported postnatally only and characterized by a typical appearance of the pons with malformations of the vermis and the cerebellar peduncles. METHODS: This retrospective multicenter study retrieved 4 cases of PTCD over a 10-year period. Prenatal ultrasonography and fetal magnetic resonance imaging (MRI) findings were reviewed and compared to postnatal or postmortem data...

BACKGROUND Congenital chloride diarrhea (CCD) is a rare autosomal recessive disorder that is difficult to distinguish from fetal lower intestinal obstruction. A prenatal diagnosis will make a contribution to the prognosis of the newborn. CASE REPORT We report a rare case of congenital chloride diarrhea (CCD) prenatally suspected by ultrasound and MRI. The prenatal ultrasound revealed signs of intestinal dilatation suggesting lower intestinal obstruction. MRI findings also revealed intestinal dilatation that continued from the rectum...

Fetal Alcohol Spectrum Disorders encompass a wide range of birth defects in children born to mothers who consumed alcohol during pregnancy. Typical mental impairments in FASD include difficulties in life adaptation and learning and memory, deficits in attention, visuospatial skills, language and speech disabilities, mood disorders and motor disabilities. Multimodal imaging methods have enabled in vivo studies of the teratogenic effects of alcohol on the central nervous system, giving more insight into the FASD phenotype...

We report our experience with foregut duplication cysts including their clinical presentation, diagnostic modalities, and surgical management. METHODS: We report a 20-year retrospective review of all foregut duplication cysts managed at our institution. RESULTS: Twelve patients with 13 foregut duplication cysts were identified. The ages of the children at the time of surgery ranged from infancy to adolescence, with a mean age of 7...

OBJECTIVE: To analyze the outcome of chromosomal microarray analysis (CMA) in prenatal diagnosis for fetal abnormalities detected by ultrasonography. METHODS: Amniotic fluid samples from 477 pregnancies with abnormal ultrasound findings but without common aneuploidies were detected by CMA with Affymetrix CytoScan 750K arrays. The results were analyzed with ChAS v3.0 software. RESULTS: Among the 477 samples, 24 (5.03%) were detected with pathogenic copy number variations (pCNVs) by CMA...

Myelomeningocele (MMC) is a costly lifetime disease with many comorbidities, including sensory and motor lower limb disability, bladder/bowel dysfunction, scoliosis, club foot, and hydrocephalus. MMC treatment options have changed over time because routine use of fetal ultrasonography and MRI has provided prenatal diagnosis and the potential for fetal surgery. There is still no consensus on how to treat the MMC diagnoses prenatally, mainly related to the infrastructure required to operate on pregnant patients...

Congenital heart disease (CHD) is an important cause of childhood mortality. Despite the widespread use of ultrasonography (US) as a screening tool, the prenatal detection rate is suboptimal. Improvement of the initial screening examination, which is performed in low-risk populations and often interpreted by community radiologists, targets a point in the screening process that is likely to have the largest population effect. If the goal of community-based screenings is to detect cases that may be abnormal and refer those to specialized centers for complete assessment, it is logical to use a checklist to confirm normal anatomy...

Pena-Shokeir phenotype is a lethal anomaly characterized by neurogenic arthrogryposis, craniofacial anomalies, and pulmonary hypoplasia. This syndrome should be distinguished from trisomy 18 and arthrogryposis multiplex congenita for better counseling and establishing fetal prognosis. We present the case of a pregnant woman diagnosed with a Pena-Shokeir phenotype affected fetus at 24 weeks of gestation. Prenatal ultrasonography and fetal magnetic resonance imaging detected persistent hyperextension of the lumbar spine, micrognathia, absent septum pellucidum, and all characteristic features of Pena-Shokeir phenotype...

Background Following the legal provisions on the termination of pregnancies in Art. 13 of the SFHG (Law on the Assistance for Pregnant Women and Families, passed on 27.07.1992, BGBl. I, p. 1398) the so-called embryopathic indication for termination was abandoned. Since then, sec. 218a para. 2 of the German Criminal Code (StGB) states that for late terminations, i.e., terminations after the 12th week of gestation post conception, the pregnant woman must be in exceptional distress "according to medical opinion"...

OBJECTIVE: To determine the correlation between pre-pregnancy body mass index (BMI) and maternal visceral adiposity with fetal biometry during the second trimester. METHODS: A cross-sectional observational study was conducted among pregnant women who received prenatal care at a center in Recife, Brazil, between October 3, 2011, and September 27, 2013. Pre-pregnancy BMI was determined at the first prenatal care visit. Maternal visceral adiposity and fetal biometry were measured at the same ultrasonography session...
