Perinatal Outcomes of Intrauterine Interventions for Fetal Sacrococcygeal Teratoma Based on Different Surgical Techniques-A Systematic Review.

Background: This study aims to evaluate the outcomes of fetal sacrococcygeal teratoma (SCT) submitted to prenatal interventions. Methods: We performed a systematic literature review of fetal SCT patients and compared the outcomes between open fetal surgery and percutaneous intervention. In addition, we also compared the results of SCT fetuses who did not undergo any surgical intervention (NI). Results: We identified 16 cases of open fetal surgery (OS), 48 cases of percutaneous fetal intervention (PI), and 93 NI patients. The survival rate was 56.2% in OS, 45.8% in PI (p = 0.568), and 71.0% in NI patients. The gestational age at delivery was earlier in cases where there was no survival compared to cases where the fetuses did survive across all evaluated cohorts (OS: p = 0.033, PI: p < 0.001, NI: p < 0.001). The gestational weeks at delivery in OS and PI fetuses were more similar; however, OS tended to be performed later on in pregnancy, and the affected fetuses had more severe presented findings. In our evaluation, we determined that the presence of fetal hydrops and cardiac failure had no significant impact on survival in SCT cases. In NI patients, polyhydramnios was much higher in fetuses who did not survive compared to their surviving cohorts (p < 0.001). Conclusions: In conclusion, gestational age at delivery can affect the short-term prognosis of fetuses affected with sacrococcygeal teratomas. Regardless of the mode of delivery or the necessity for intervention during the fetal period, monitoring for complications, including polyhydramnios, can prevent premature delivery.

3D ultrasound angioscan with MV-Flow™: Enhancing fetal brain low-flow microvascular neuroimaging.

MVFlow™ is a 3D algorithm that enhances the study of the microvasculature, useful in the study of tumoral lesions or in assessing the slow-flow of the placenta vessels and the developing fetal brain. It may improve the study of the corpus callosum in normal fetuses and be applied in the characterization of brain pathologies.

Ectopia cordis: prenatal diagnosis, perinatal outcomes, and postnatal follow-up of an international multicenter cohort case series.

OBJECTIVE: This study aimed to analyze prenatal diagnosis, perinatal outcomes, and postnatal follow-up in fetuses with ectopia cordis (EC). METHODS: This retrospective analysis accessed 31 patients with EC who were either diagnosed or referred to a tertiary Fetal Medicine centers for EC diagnosis in Brazil, Germany, Italy, and Poland. We analyzed prenatal diagnosis, perinatal outcomes, and follow-up in these patients. RESULTS: Our study included a cohort of 31 fetuses with EC, 4 and 27 of whom had partial and complete protrusion of the heart through a ventral defect in the thoracoabdominal wall, respectively. EC was diagnosed by fetal echocardiography at a mean gestational age of 20.3 ± 8.6 weeks (range, 8-35 weeks). Of the four cases, in which the karyotype was performed, all of them had a normal result (1 - 46,XX and 3 - 46,XY). Five patients showed conotruncal abnormalities and six ventricular septal defects. Termination of pregnancy (TOP) was performed in 15 cases (48%) and seven pregnant women had spontaneous fetal demise (22.5%). Of the seven fetuses that were born alive, four of them died, and three infants underwent surgery. Among these three infants, all of them survived, one was 5 months, 13 years old and 29 years old at the time of study completion. CONCLUSIONS: Ectopia cordis is associated with high mortality rates and intracardiac/extra-cardiac defects. Ventricular septal defects and conotruncal anomalies were the more common intracardiac defects associated with EC. However, in this cohort of fetuses with EC the incidence of PC was lower than reported in the literature.

Fetal Hands: A Comprehensive Review of Prenatal Assessment and Diagnosis Over the Past 40 Years.

Fetal skeletal dysplasias involving limbs and hands are rare congenital malformations. Prenatal two-dimensional ultrasound diagnosis of fetal limb defects has a sensitivity of about 30%; however, an increased detection rate may be obtained using three-dimensional (3-D) ultrasound in the rendering mode. 3-D ultrasound may be used as a complementary method providing additional information. Currently, magnetic resonance imaging (MRI), with the emergence of ultrafast imaging techniques and new sequences, allows for better diagnosis of several fetal skeletal dysplasias such as limb reduction defects and neuromuscular disorders. 3-D volumetric images from ultrasound or MRI scan data allow 3-D ultrasound reconstructions of virtual/physical models, and virtual reality can help researchers to improve our understanding of both normal and abnormal fetal limb/hand anatomy. In this article, we review the embryological development of fetal hands and their main anomalies including prenatal diagnostic methods, genetic counseling, the role of orthopedic and plastic surgery reconstruction, and new perspectives in fetal surgery.

Bronchopulmonary dysplasia: Can we provide a link between prenatal and postnatal lung ultrasound?

The role of lung ultrasound in the prediction of bronchopulmonary dysplasia.

Maternal-fetal alloimmunization: perinatal outcomes in a reference hospital in Northeastern Brazil

SUMMARY OBJECTIVE: To assess the prevalence of maternal alloantibodies in pregnant women at a maternity hospital in northeastern Brazil and describe their perinatal outcomes. METHODS: A retrospective cohort study reviewed maternal and newborn medical records between January 2017 and October 2018 to assess for the presence of maternal alloantibodies. RESULTS: The following maternal alloantibodies were found in the 41 cases surveyed: anti-D, 28 cases (45%); anti-C, 7 cases (11%); anti-c, 1 case (1.6%); anti-E, 4 cases (6.4%); anti-Cw, 1 case (1.6%); anti-K, 2 cases (3.2%); anti-Jka, 1 case (1.6%); anti-M, 3 cases (4.8%); anti-Fya, 2 cases (3.2%); anti-Fyb, 1 case (1.6%); anti-Lea, 5 cases (8%); anti-Leb, 3 cases (4.8%); and anti-Dia, 4 cases (6.4%). Anti-D antibodies were the most frequent cause of erythrocyte alloimmunization (80%). Fetal anemia was observed in four pregnancies based on the peak systolic velocity of the middle cerebral artery. In one case, the mother showed anti-M, and anti-Lea alloimmunization, but the direct antiglobulin test results for the newborn were negative, and no unfavorable neonatal outcomes were observed. In one case of a mother with anti-C and anti-D alloimmunization, the neonate showed anti-D antibodies only in the serological panel and required phototherapy. Neonates with plasma antibodies and jaundice requiring phototherapy only had a serological panel with anti-D, anti-C, anti-c, and anti-E antibodies. Intervention was required for 2.5% of pregnant women with positive antibody screens and 81% of newborns with positive direct antiglobulin test results. CONCLUSION: Despite being a rare condition, maternal alloimmunization by irregular antibodies can result in high perinatal morbidity and mortality.

Early Prenatal Ultrasound and Molecular Diagnosis of Apert Syndrome: Case Report with Postmortem CT-Scan and Chondral Plate Histology.

Background Apert syndrome is characterized by craniosynostosis, midface hypoplasia and symmetric syndactyly. Case report: A 36-year-old mother, G2P1 underwent an ultrasound scan at 19 week's gestation. There was craniosynostosis, brachi-turricephaly and bilateral hand syndactyly. Genomic DNA from amniocentesis revealed the mutation C758C>Gp. (Pro to Arg substitution) at 252 of the exon 8 of the FGFR2 encoding for Apert syndrome. The pregnancy was terminated. Femoral chondral plate histology showed an increased interstitial matrix between bony trabeculae. Compared with normal, the trabeculae were thinner, more irregular with numerous osteoclasts suggesting abnormal bone remodeling. Hands and feet had an abrupt transition between resting and proliferating cartilage. Conclusion: Apert syndrome has increased intertrabecular matrix, thin trabeculae, increased remodeling, and irregular transition between the maturing and mineralization zones in the femur, and abnormal abrupt transition between the resting and proliferating cartilage in the fingers and toes.

Prenatal Diagnosis of Fetal Trisomy 5 Mosaicism with Congenital Pulmonary Airway Malformation Type 3: A Case Report.

Background: Trisomy mosaicism of chromosome 5 is uncommon with few cases described. Case report: A 41-year-old woman underwent ultrasound (US) at 16 weeks, which showed oligohydramnios and intrauterine growth restriction (IUGR). Amniocentesis discovered a karyotype of 47,XX,+5/46,XX. US at 19 weeks disclosed IUGR, enlargement of right side of heart, main pulmonary artery dilatation, and a suspected congenital pulmonary airway malformation (CPAM) in the inferior lobe of the left lung. Due to poor fetal prognosis, the parents opted for legal termination of pregnancy. At postmortem, a wide ventricular septal defect and CPAM type 3 were found. Cytogenetic analyses on fetal tissues detected mosaic trisomy 5 in skin, thymus, kidneys and CPAM. Placenta and fetal peripheral blood revealed normal female karyotype. Discussion/conclusion: These results suggest that if a fetus presents normal phenotypic features, mosaicism may be confined to extraembryonic structures, otherwise, in case of malformations, it may be carried by affected organs.

Covid-19 and pregnancy: an overview / Covid-19 e gravidez: uma visão geral

Abstract Since the World Health Organization (WHO) declared coronavirus infection (COVID-19) a Public Health Emergency of International Concern in January 2020, there have been many concerns about pregnant women and the possible effects of this emergency with catastrophic outcomes inmany countries. Information on COVID-19 and pregnancy are scarce and spread throughout a fewcase series, with no more than 50 cases in total. The present review provides a brief analysis of COVID-19, pregnancy in the COVID-19 era, and the effects of COVID-19 on pregnancy.

Resumo Desde que a Organização Mundial da Saúde (OMS) declarou a infecção por coronavírus (COVID-19) uma emergência de saúde pública de interesse internacional emjaneiro de 2020, houve muitas preocupações sobre mulheres grávidas e os possíveis efeitos dessa emergência com resultados catastróficos em muitos países. As informações sobre COVID-19 e gravidez são escassas e se espalham por algumas séries de casos, com não mais do que 50 casos no total. A presente revisão fornece uma breve análise da COVID- 19, gravidez na era COVID-19 e os efeitos da COVID-19 na gravidez.

Tocolysis for open prenatal repair of myelomeningocele: systematic review.

Objectives: To summarize current evidence on the use of tocolytic medications perioperatively for open prenatal repair of fetal myelomeningocele including tocolytic agent options, regimens, efficiency, and potential risks.Methods: A search of Medline, Embase, and SCOPUS databases was conducted from inception to March 2017. Studies that described their tocolytic protocol, gestational age at delivery, perinatal outcomes were included. Studies that did not exclusively assessed fetal myelomeningocele or did not adequately endorse obstetric and neonatal outcomes were excluded. Neither sample size nor language was a basis for exclusion.Results: Out of 570 studies retrieved on initial search, 462 were excluded for irrelevance. Of the 61 remaining titles, 17 were animal studies, 17 were reviews, 12 studied a spectrum of anomalies, three specified fetoscopy, four did not report neonatal outcomes, and one article was retracted. Two studies were added to the pool when the literature search was updated. Nine articles were eventually included; three case reports, six cohort studies with a total of 205 cases. Fetuses were managed at gestational ages between 19 and 30 weeks. Although tocolytic regimens were variable, indomethacin was commonly utilized as a preoperative tocolytic. Magnesium sulfate was usually initiated intraoperatively and was resumed postoperatively for a variable duration (18-48 hours) with or without subcutaneous terbutaline. Gestational age at delivery ranged from 30-37 weeks with an average of 33-35 weeks. Pulmonary edema was reported in two studies to be 2.2-5.5%. Perinatal outcomes were overall favorable.Conclusion: Preoperative indomethacin and postoperative course of magnesium sulfate seem to be a favorable tocolytic option in women with open prenatal myelomeningocele repair. Risks are generally minimal. However, adequate information on the duration of postoperative tocolysis seems to be inadequate.

Acrania-exencephaly-anencephaly sequence phenotypic characterization using two- and three-dimensional ultrasound between 11 and 13 weeks and 6 days of gestation.

The study presents a pictorial essay of acrania-exencephaly-anencephaly sequence using two-(2D) and three-dimensional (3D) ultrasonography, documenting the different phenotypic characterization of this rare disease. Normal and abnormal fetuses were evaluated during the first trimester scan. The International Society of Ultrasound in Obstetrics and Gynecology practice guidelines were adopted to standardize first trimester anatomical ultrasound screening. The guidelines outline the importance of systematic fetal head and brain examination including the formation of cranial bones, choroid-plexus and ventricles. Acrania-exencephaly-anencephaly sequence and/or other neural tube defects, such as meningoencephalocele, may be identified during a routine 11-14 week scan. Early first trimester detection of acrania-exencephaly-anencephaly sequence with the characterization of different related phenotypes, 2D and 3D ultrasound imaging as well as differential diagnosis are also presented in this pictorial essay. The main diagnostic ultrasound features of the disease may be characterized by findings of acrania with increased amniotic fluid echogenicity; "Mickey-Mouse" bi-lobular face, cystic, elongated, irregular and overhanging head morphology. Lightening techniques have also been added to 3D ultrasound to enhance anatomical details. Moreover, discordant amniotic fluid echotexture in the setting of twin pregnancies may be the first sign of acrania-exencephaly-anencephaly sequence. Extracranial malformations, aneuploidy and genetic syndromes associated with acrania-exencephaly-anencephaly sequence are also reported and described. First trimester neuroscan by an expert sonographer with appropriate training together with the application of standardized protocol are essential for a high detection rate of this rare type of neural tube defect malformation during a scan performed at 11 and 13 weeks and 6 days.

Early Prenatal Diagnosis of Blakes' Pouch Cyst by 2D/3D Ultrasound with Cristal and Realistic Vue Application.

INTRODUCTION: Blake's pouch cyst (BPC) represents an abnormal development of the posterior membranous area of the fetal brain. MATERIAL AND METHODS: Two- and three-dimensional ultrasound with Cristal and Realistic Vue were used to characterized the early prenatal diagnosis. RESULTS: At 9 weeks and 5 days a ballooning in the posterior fossa and resulting in an enlarged intracranial translucency (IT) was detected by 3D ultrasound using Cristal Vue in "inversion" mode and Cristal plus Realistic Vue. In addition, an increased nuchal translucency (7 mm) due to septated cystic hygroma (SCHy) was an associated finding. Hydrops fetalis ensued and a chorionic villus sampling at 12 weeks revealed a 45,X monosomy with persisting BPC. Follow up scan were planned fortnightly. A spontaneous miscarriage occurred at 16 weeks. CONCLUSION: Three-dimensional ultrasound with Cristal and Realistic Vue aided the prenatal diagnosis of BPC in the first trimester.

3D Virtual Broncoscopy before FETO Procedure in a Fetus with Severe, Isolated Left Congenital Diaphragmatic Hernia.

INTRODUCTION: Congenital diaphragmatic hernia (CDH) is a life-threatening event in severe forms and fetuses affected may benefit from in utero treatment by fetoscopic endotracheal occlusion (FETO). MATERIALS AND METHODS: Application of 3D virtual bronchoscopy in a case of severe, isolated, left CDH before performing FETO procedure at 27 week's gestation is reported. RESULTS: The 3D virtual imaging of the fetal trachea was technically useful in planning the real FETO procedure. FETO successfully promoted fetal lung growth by decreasing the herniation of abdominal organs into the thorax and decreasing the risk of pulmonary hypoplasia. Ultrasound calculation of lung to head ratio (LHR) and fetal-MRI were used to assess lung development following FETO procedure. CONCLUSION: 3D virtual fetal reality enabled the fetal surgeon to review and navigate on demand inside the upper airway, reducing the risk of unexpected intervention complications.

TRAP Sequence in Monochorionic/Monoamniotic (MC/MA) Discordant Twins: Two Cases Treated with Fetoscopic Laser Surgery.

INTRODUCTION: Ablation of the acardiac twin umbilical cord in the TRAP protects the normal donor twin. MATERIALS AND METHODS: Two case descriptions, one of interstitial laser photocoagulation and one of laser umbilical cord occlusion (L-UCO) of the acardiac twin in monochorionic monoamniotic pregnancies are reported. RESULTS: L-UCO in two pregnancies with TRAP syndrome in the second trimester resulted in intrauterine fetal death in both cases after 1 month. Case 1 had no detectable cause of fetal death. Case 2 had rupture of the amniotic sac causing anhydramnios and acute chorioamnionitis. A groove on the umbilical cord of the normal twin indicated a cord stricture due to cord entanglement. CONCLUSION: Our experience confirms that the best timing and optimal treatment of MC/MA twins complicated by TRAP sequence still remains a controversial clinical issue. Cord entanglement may continue be a potential clinical risk factor for adverse perinatal outcome even after ablation therapy.

Vulvar involvement in pediatric Crohn's disease: a systematic review.

PURPOSE: The aim of the study is to report a systematic review (from 2000 to 2017) of all pediatric cases of vulvar Crohn's disease (VCD) and to highlight the key-points for a correct diagnosis and management of this rare condition. METHODS: An electronic search using the Pubmed/Medline, Scopus, EMBASE, Cochrane database and Google Scholar database was performed according to PRISMA guidelines. RESULTS: Twenty pediatric studies and 22 cases of VCD were included for analysis. All the articles reported a single case, except two articles where two cases, respectively, are described. Clinical vulvar examination showed the following main manifestations: vulvar erythema (9/22 cases, 40.9%), vulvar swelling (8/22 cases, 36.4%), vulvar edema (8/22 cases, 36.4%), vulvar ulcers (4/22 cases, 18.2%). Perianal and/or anal involvement (fissures, vegetations, skin tags, erythema, papules, nodules) were recorded in ten cases (45.4%). Steroids per os and/or topical administration were the most prescribed treatment, achieving clinical remission in 11 cases (50%), used alone or in combination with metronidazole or 5-aminosalicylic acid, azathioprine or sulphasalazine/mesalazine. CONCLUSIONS: This review shows that pediatric VCD is an uncommon disease, difficult to be diagnosed as either symptoms or clinical lesions are not specific. A multidisciplinary approach is advised to reach a correct diagnosis and plan clinical treatment.

Prenatally diagnosed fetal tumors of the head and neck: a systematic review with antenatal and postnatal outcomes over the past 20 years.

AIM: The aim of this study was to review prenatally diagnosed tumors of the head and neck in the fetus and to report antenatal and postnatal outcomes. METHODS: PubMed/Medline, EMBASE/SCOPUS, Cochrane database and Google Scholar were reviewed over the last 20 years. No language or article type restriction was used. RESULTS: A total of 1940 record were retrieved. Of the 713 records screened, 566 full-text articles were assessed for eligibility. After 445 articles were excluded for specified reasons, 111 studies met the research criteria and were included for qualitative analysis. Overall, 306 cases of fetal tumors of the head and neck were reviewed. Maternal age was an independent factor. The mean maternal age was 28.2 years and gestational age at prenatal diagnosis was 27.1 weeks. Conventional 2D ultrasound was the standard diagnostic procedure in 27.9% of cases and was implemented in 27.3% of cases by 3D ultrasound and fetal magnetic resonance imaging (MRI). Diagnostic evaluation of intracranial spreading and high-airway obstructions was greatly enhanced by fetal MRI. The more common type of fetal tumor was hemangioma/lymphangioms (42.1%), followed by teratomas (29.7%), tumors of the gingiva (10.1%) and lymphatic venous malformations (9.1%), respectively. Fetal karyotyping was performed only in 9.8% of cases; within fetuses undergoing karyotype, chromosomal abnormalities accounted for 20% of cases. The most common pregnancy complication was polyhydramnios (26.3%). Ex utero intrapartum treatment (EXIT) procedure was performed in 30.1% of cases while surgical excision was used in 22.9% during postnatal life. The survival rate was 35.35%. CONCLUSION: Fetal tumors of the head and neck are rare congenital malformations. Two-dimensional ultrasound is diagnostic in almost all cases; however, MRI may be an important diagnostic adjunct in targeted cases and help patient selection for immediate intubation at the time of delivery. EXIT procedure and surgical removal of the tumor was associated with good prognosis.

Procedure-Related Complications and Survival Following Fetoscopic Endotracheal Occlusion (FETO) for Severe Congenital Diaphragmatic Hernia: Systematic Review and Meta-Analysis in the FETO Era.

Introduction This study aims to assess the procedure-related complications and survival following fetoscopic endotracheal occlusion (FETO) for severe congenital diaphragmatic hernia. Materials and Methods A systematic review and meta-analysis of PubMed and Scopus database searching for FETO procedure in severe CDH (lung-to-head ratio [LHR] < 1.0 and/or observed/expected LHR < 0.26 and > 1/3 liver herniation) were performed. The relative risk was assessed and 95% confidence interval (CI) calculated. Procedure complications and survival were compared between FETO and randomized controlled trial (RCT) as well as observational case-control studies. Results A total of 4,807 records were retrieved based on the title and abstracts, and 18 studies were eligible for statistical analysis (1 RCT and 17 observational case-control studies). Relative risk (95% CI) comparing FETO and controls for premature rupture of membrane, preterm birth < 32 weeks, preterm birth < 37 weeks, survival at 30 days, and survival at 6 months were 1.7 (0.8-2.4), 7.3 (0.4-134), 1.8 (0.8-3.9), 5.8 (1.5-22.9), and 10.5 (1.5-74.7), respectively. Mean difference (95% CI) for gestational age at delivery comparing FETO and controls was 1.8 (-3.1 to -0.5). All these outcomes showed a low level of evidence. Conclusion FETO procedure increased the neonatal survival at 30 days and 6 months; however, it presented a higher rate of premature rupture of membrane, preterm birth < 37 weeks, and decreased the gestational age at delivery by 2 weeks. Nonetheless, the level of evidence is low for all these outcomes. We suggested a large international multicenter RCT to prove the real benefits of FETO.

Neurological Outcome in Fetuses with Mild and Moderate Ventriculomegaly / Resultado neurológico em fetos com ventriculomegalia leve e moderada

Abstract Introduction Ventriculomegaly (VM) is one the most frequent anomalies detected on prenatal ultrasound. Magnetic resonance imaging (MRI) may enhance diagnostic accuracy and prediction of developmental outcome in newborns. Purpose The aim of this study was to assess the correlation between ultrasound and MRI in fetuses with isolated mild and moderate VM. The secondary aim was to report the neurodevelopmental outcome at 4 years of age. Methods Fetuses with a prenatal ultrasound (brain scan) diagnosis of VM were identified over a 4-year period. Ventriculomegaly was defined as an atrial width of 10- 15 mm that was further divided as mild (10.1-12.0 mm) and moderate (12.1-15.0 mm). Fetuses with VM underwent antenatal as well as postnatal follow-ups by brain scan and MRI. Neurodevelopmental outcome was performed using the Griffiths Mental Development Scales and conducted, where indicated, until 4 years into the postnatal period. Results Sixty-two fetuses were identified. Ventriculomegaly was bilateral in 58% of cases. A stable dilatation was seen in 45% of cases, progression was seen in 13%, and regression of VM was seen in 4.5% respectively. Fetal MRI was performed in 54 fetuses and was concordant with brain scan findings in 85% of cases. Abnormal neurodevelopmental outcomes were seen in 9.6% of cases. Conclusion Fetuses in whom a progression of VM is seen are at a higher risk of developing an abnormal neurodevelopmental outcome. Although brain scan and MRI are substantially in agreement in defining the grade of ventricular dilatation, a low correlation was seen in the evaluation of VM associated with central nervous system (CNS) or non-CNS abnormalities.

Resumo Introdução Ventriculomegalia (VM) é uma das anomalias mais frequente no ultrassom pre-natal. Ressonâncias magnéticas (RM) melhoram a precisão do diagnóstico e previsão do desenvolvimento em recém-nascidos. Objetivo A proposta deste estudo foi avaliar a correlação entre ultrassom e RM em fetos com leve e moderada VM isolada. O objetivo secundário foi reportar o resultado neurológico na idade de 4 anos. Métodos Fetos com diagnóstico pré-natal pelo ultrassom de VM foram identificados na idade de 4 anos. Ventriculomegalia foi definida como medida do átrio do ventrículo lateral entre 10-15 mm, a qual foi subdividida em leve (10,1-12,0 mm) e moderada (12,1-15,0 mm). Fetos com VM foram seguidos nos períodos pré-natal e pós-natal por ultrassom e RM. O resultado neurológico foi realizado usando a escala de desenvolvimento mental de Griffiths, quando indicada, até a idade de 4 anos. Resultados Sessenta e dois fetos foram identificados. Ventriculomegalia bilateral ocorreu sem 58% dos casos. Uma dilatação estável foi observada em 45%, progressiva em 13% e regressiva em 4,5% dos casos, respectivamente. Ressonância magnética fetal foi realizada em 54 fetos, e foi concordante com os achados do ultrassom em 85% dos casos. Desenvolvimento neurológico anormal foi observado em 9,6% dos casos. Conclusão Fetos nos quais ocorreu progressão da VM são de alto risco para desenvolvimento neurológico anormal. Apesar do ultrassom e da RM mostrarem substancial concordância na definição do grau de dilatação ventricular, uma baixa correlação foi vista na avaliação da VM associada ou não com anomalias do sistema nervoso central.
