Rebekah Kaplan, Sharon Adams
Ultrasonography is a common component of prenatal care worldwide and is often used in early pregnancy to determine gestational age, number of fetuses, fetal cardiac activity, and placental location. Patients and their families may also consider ultrasonography a social event, as it provides confirmation and reassurance of a normal pregnancy. Ultrasound screening is typically scheduled in the second trimester to visualize fetal anatomy and confirm gestational age. Most ultrasound examinations are reassuring, but some incidentally identify structural anomalies and soft markers for aneuploidy, making it necessary for health care providers to correctly interpret these findings...

Porencephaly and schizencephaly are congenital brain disorders that can be caused by COL4A1 mutations, though the underlying mechanism and developmental processes are poorly understood. Here, we report a patient with schizencephaly, detected by fetal ultrasonography and fetal magnetic resonance imaging, with a de novo novel mutation in COL4A1 (c.2645_2646delinsAA, p.Gly882Glu). Our results suggest that the onset of damage that potentially results in schizencephaly occurs mid-pregnancy.

The aim of the study described here was to identify an efficient criterion for the prenatal diagnosis of abnormal invasive placenta. We evaluated 129 women with anterior placenta previa who underwent trans-abdominal ultrasound evaluation in the third trimester. Spectral Doppler ultrasonography was performed to assess the subplacental blood flow of the anterior lower uterine segment by measuring the highest peak systolic velocity and resistive index. These patients were prospectively followed until delivery and evaluated for abnormal placental invasion...

BACKGROUND: Ultrasonography is essential in the prenatal diagnosis and care for the pregnant mothers. However, the measurements obtained often contain a small percentage of unavoidable error that may have serious clinical implications if substantial. We therefore evaluated the level of intra and inter-observer error in measuring mean sac diameter (MSD) and crown-rump length (CRL) in women between 6 and 10 weeks' gestation at Mulago hospital. METHODS: This was a cross-sectional study conducted from January to March 2016...

Posterior urethral valve (PUV) rarely causes bladder rupture. We experienced hydronephrosis due to ureteral obstruction after the natural repair of a ruptured bladder in a fetus with PUV. Fetal ascites and oligohydramnios were diagnosed at 26 weeks' gestational age. While we followed up with ultrasonography, we regularly removed the fetal ascites via abdominal puncture, injecting warm saline instead of amniotic fluid. At 35 weeks' gestational age, the infant was diagnosed with severe bilateral hydronephrosis, absent of ascites and oligohydramnios...

History A 3-month-old previously healthy girl presented to an outside institution with a 4-day history of low-grade fever, irritability, and a tender "knot" in the upper abdomen. Ultrasonography (US) was performed at an outside hospital. US images were not available for review; however, they showed a mass in the left hepatic lobe, per the outside report, and the patient was referred to our institution for further evaluation. Her parents reported a normal full-term pregnancy, with regular prenatal care and normal prenatal US findings...

The human face is a complex anatomic structure with an equally complex embryologic development. Derangement of the developmental process can result in various structural anomalies, which range from a mainly cosmetic deformity, such as cleft lip, to potentially life-threatening conditions such as arhinia. These anomalies (a) can occur as isolated anomalies; (b) can be associated with intracranial, spinal, or dental anomalies; or (c) can be a part of various syndromes, thus serving as diagnostic clues in such cases...

BACKGROUND: The data from literature show that trial of labor and elective repeat cesarean delivery after a prior cesarean delivery both present significant risks and benefits, and these risks and benefits differ for the woman and her fetus. The benefits to the woman can be at the expense of her fetus and vice-versa. This uncertainty is compounded by the scarcity of high-level evidence that preclude accurate quantification of the risks and benefits that could help provide a fair counseling about a trial of labor and elective repeat cesarean delivery...

PURPOSE: Signs of congenital obstruction of the gastrointestinal tract (GIT) organs may present on prenatal ultrasonography. Prenatal detection is influenced by several factors, including obstruction site, lesion degree (partial or complete), the occurrence of associated malformations, and gestational week at screening. Here, we aimed to evaluate the success of prenatal diagnosis of GIT obstructions in a tertiary center in Turkey. MATERIALS AND METHODS: The study included 34 prenatally and 22 postnatally diagnosed babies with different GIT malformations...

REVIEW
Neil O'Gorman, Laurent J Salomon
Ultrasound assessment of fetal size is central to modern practice of prenatal care. It facilitates accurate pregnancy dating and screening for fetal growth disorders. This article discusses evidence-based recommended methods for pregnancy dating and biometric measurements. We address some confusing terms such as fetal growth "standards" and fetal growth "references" along with explaining the differences between prescriptive and descriptive charts and between growth charts based on estimated fetal weight vs those based on birth weight...

Prenatal ultrasonography (US) in a 39 year-old woman revealed massive fetal ascites. A fetal abdomino-amniotic shunting procedure was performed. Subsequently, plain radiographs demonstrated diffuse gaseous distention of the bowel and multiple punctate calcifications in the left upper abdomen. Postnatal US examination showed multiple echogenic foci in the liver and the left upper abdomen, bowel wall thickening in the right-sided abdomen, and undescended testes. There was no intra-abdominal free air or loculated fluid collections...

Congenital heart disease (CHD) seriously threatens fetal health. Therefore, prenatal examination to detect deformity is extremely important. The present study aimed to investigate the clinical application value of prenatal ultrasonography combined with molecular biology methods in the diagnosis of fetal CHD. A total of 1,000 pregnant women who had received fetal ultrasonography to examine fetal CHD were enrolled. Ultrasounds were performed for fetal heart examination and diagnosis, mainly on fetal heart position, size, structure and function, and heart valve morphology and function...

Neuroblastoma is the most common pediatric extracranial solid tumor derived from primitive neural crest cells of the sympathetic nervous system. Although one-fifths of all neuroblastomas occurs within the thorax, thoracic neuroblastomas detected in fetus have been rarely reported. We report a case of fetal thoracic neuroblastoma with massive pleural effusion detected with prenatal ultrasonography. A 34-year-old Korean second-gravida was referred to our hospital at 30 weeks of gestation for evaluation, after the right lung mass found in the fetus...

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.

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...
