ABSTRACT
OBJECTIVES: This retrospective study aimed to assess disparities between prenatal ultrasound and autopsy findings in pregnancies that resulted in fetal loss, and to evaluate the diagnostic performance of prenatal ultrasound using postmortem examinations as a gold standard. METHODS: Our study included 136 autopsy cases following a fetal loss that occurred at our tertiary medical center for 8 years. A comparison between the prenatal ultrasound and autopsy findings was made, and all cases were classified according to the degree of agreement. The diagnostic performance of prenatal ultrasound was calculated at the level of organ system and specific malformations. RESULTS: The primary sonographic diagnosis was confirmed in 91.9% of the cases (n = 125). General agreement was highest among central nervous system (CNS), cardiovascular and musculoskeletal systems (85.7%, n = 36, 18, and 12, respectively) and lowest among facial, multiple anomalies, genitourinary and gastrointestinal systems (50.0%, 74.3%, 78.6%, and 80.0%, n = 2, 26, 11, and 4, respectively). The sensitivity of ultrasound was highest in the CNS (93.2%) and musculoskeletal (87.0%) and lowest in the facial (32.3%) and pulmonary (13.0%) systems. Specifically, low diagnostic rates were noted in detecting ventriculomegaly, valvular anomalies, renal dysplasia, spleen and adrenal anomalies, and digital and facial defects. CONCLUSIONS: Our study observed an overall high agreement between prenatal ultrasound and autopsy while contributing to our comprehensive understanding of its strengths and limitations across various types of organ systems and specific malformations.

PURPOSE: The study aimed to evaluate the causes of death and associated factors in cases of stillbirth, using post-mortem examination and applying a rigorous, evidence-based holistic approach. METHODS: Our retrospective observational study included cases of autopsy following stillbirth that occurred at our tertiary medical center during a period of 8 years. Detailed up-to-date criteria that incorporate clinical reports, medical history, prenatal imaging, and histopathological findings were used to evaluate the cause of death and associated factors. RESULTS: After applying our proposed methodology, 138 cases of stillbirth were classified into eight categories based on the causes of death. A definitive cause of death was observed in 100 (72%) cases, while 38 (28%) cases were considered unexplained. The leading cause of death was placental lesions (n = 39, 28%) with maternal vascular malperfusion (MVM) lesions being the most common (54%). Ascending infection was the second most common cause of fetal death (n = 24, 17%) and was often seen in the setting of preterm labor and cervical insufficiency. CONCLUSION: The largest category of cause of death was attributed to placental pathology. Using rigorous detailed up-to-date criteria that incorporate pathological and clinical factors may help in objectively classifying the cause of death.
ABSTRACT
PURPOSE: Fetal growth assessment is a key component of prenatal care. Sex-specific fetal brain nomograms on ultrasound are available and are clinically used. In recent years, the use of fetal MRI has been increasing; however, there are no sex-specific fetal CNS nomograms on MRI. The study aimed to assess the differences in fetal brain biometry and growth trajectories and to create population-based standards of the fetal brain on MRI. METHODS: In this cross-sectional study, brain structures of singleton fetuses with normal brain MRI scans were analyzed: biparietal diameter, occipitofrontal diameter, trans-cerebellar diameter, and the corpus callosum were measured and converted into centiles. Sex-specific nomograms were created. RESULTS: A total of 3848 MRI scans were performed in one tertiary medical center between 2011 and 2019; of them, 598 fetuses met the inclusion criteria, 300 males and 298 females between 28- and 37-weeks' gestation. Males had significantly larger occipitofrontal diameter than females (median 75%, IQR 54-88%; median 61%, IQR 40-77%) and biparietal diameter (median 63%, IQR 42-82%; median 50%, IQR 25-73%), respectively (p < 0.001). The cerebellum had the greatest growth rate, with a 1.5-fold increase in diameter between 28 and 37 weeks' gestation, with no measurement difference between the sexes (p = 0.239). No significant difference was found in the corpus callosum (p = 0.074). CONCLUSION: Measuring both sexes on the same nomograms may result in over-estimation of male fetuses and under-estimation of females. We provide fetal sex-specific nomograms on two-dimensional MRI.

BACKGROUND: Health systems around the world have begun implementing unique tracks to expedite diagnosis and improve survival of patients with suspected cancers. This study aimed to compare characteristics and survival between patients diagnosed by way of fast and regular diagnostic tracks. METHODS: A historical cohort study of patients (age ≥ 18) diagnosed with lung or pancreatic cancers between 09/2017 and 03/2020 on a fast diagnostic track and treated in a tertiary hospital versus a random sample of patients with the same cancer types who began treatment in the hospital over the same period of time after being diagnosed utilizing the regular track in the community. RESULTS: The study included 336 patients (108 fast-track diagnostics, 228 regular track diagnostics). Advanced stages III-IV at diagnosis were more likely in the fast-track group (94.4% vs. 81.1%, p = 0.001). The median time from initial cancer suspicion to diagnosis was 21 days (IQR 14-37) for the fast-track vs. 31 days (IQR 18-51) for the regular track (p < 0.001). During the follow-up period, 56 patients from the fast-track and 131 patients from the regular track died. No significant difference was found in the median survival time between the fast and regular tracks, whether from the onset of symptoms, diagnosis, or treatment initiation. CONCLUSION: Patients referred to the fast-track were more likely to be diagnosed at a further advanced stage of their cancer. The fast-track shortened the time until diagnosis and treatment but no difference was found in median survival between the tracks, perhaps due to late referral and high fatality rates.

INTRODUCTION: The subarachnoid space (SAS) is a potential space surrounding the brain where the cerebrospinal fluid (CSF) flows. Previous work demonstrated how the SAS width changes during pregnancy and measured the normal values per gestational week. OBJECTIVES: Studying the ratio between the fetal brain volume (STV) and the SAS width (SS ratio), as measured via fetal magnetic resonance imaging (MRI) in different fetal pathologies - macrocephaly and microcephaly, and studying the correlation between this ratio and the gestational week. METHODS: A retrospective study was conducted on 77 fetuses that underwent fetal MRI scans during gestational weeks 29-37, in three groups: 23 normocephaly, 27 macrocephaly, and 27 microcephaly. SAS width was measured in 10 points via fetal MRI scans, and a ratio was calculated between the width and STV. RESULTS: The SS ratio is largest in microcephaly group and smallest in normocephaly group, with the macrocephaly group between them. All comparisons were statistically significant except between the macrocephaly and normocephaly groups. There was a strong positive correlation between SS ratio and week of gestation. CONCLUSIONS: The SS ratio is statistically different between normocephalic fetuses and fetuses with macrocephaly or microcephaly. From week 29 this ratio enlarges with gestational age. DISCUSSION: The SAS affects the fetal head circumference, an important parameter of fetal growth, thus we decided to study the SS ratio in pathologies of the head circumference. Previous work demonstrated how the STV and the SAS width expand starting at a specific gestational age, thus the gestational week also affects the SS ratio. Summary: The SS ratio is affected by pathologies of the fetal head circumference and by gestational age.

PURPOSE: Apparent diffusion coefficient (ADC) values in the developing fetus provide valuable information on the diagnosis and prognosis of prenatal brain pathologies. Normative ADC data has been previously established in 1.5 T MR scanners but lacking in 3.0 T scanners. Our objective was to measure ADC values in various brain areas in a cohort of normal singleton fetuses scanned in a 3.0 T MR scanner. METHODS: DWI (diffusion-weighted imaging) was performed in 47 singleton fetuses with normal or questionably abnormal results on sonography followed by normal structural MR imaging. ADC values were measured in cerebral lobes (frontal, parietal, temporal lobes), basal ganglia, and pons. Regression analysis was used to examine gestational age-related changes in regional ADC. RESULTS: Median gestational age was 30.1 weeks (range, 26-34 weeks). There was a significant effect of region on ADC values, whereby ADC values were highest in cerebral lobes (parietal > frontal > temporal lobes), compared with basal ganglia. The lowest values were found in the pons. On regression analysis, there was a decrease in ADC values in basal ganglia and pons with increasing gestational age. ADC values in frontal, parietal, and temporal lobes were stable in our cohort. CONCLUSION: Regional brain ADC values in 3.0 T scanners are comparable with previously reported values in 1.5 T scanners, with similar changes over gestational age. Using 3.0 T scanners is increasing worldwide. For fetal imaging, establishing normal ADC values is critical as DWI enables a sensitive and quantitative technique to evaluate normal and abnormal brain development.

OBJECTIVE: This study employed magnetic resonance imaging (MRI) to compare brain volumes of discordant twins and examined their neurodevelopment after birth by using a validated exam. STUDY DESIGN: A prospective historical cohort study of discordant dichorionic diamniotic (DCDA) or monochorionic diamniotic (MCDA) twin fetuses, who undergone an MRI scan to evaluate growth restriction in the discordant twin (weight < 10th centile) during 6 years period, at a single tertiary center. Twenty-seven twin pairs were included in the volumetric study and 17 pairs were included in the neurodevelopmental outcome examination. The volumes of the supratentorial brain region, both hemispheres, eyes, and the cerebellum were measured by 3D MRI semi-automated volume measurements. Volumes were plotted on normal growth curves and discordance was compared between weight at birth and brain structure volumes. Neurodevelopmental outcome was evaluated using the VABS-II questionnaire at a mean age of 4.9 years. RESULTS: The volume of major brain structures was significantly larger in the appropriate-for-gestational-age twins (AGA) compared to the small-for-gestational-age (SGA) co-twins (p < 0.001). The birth weight discordance was 32.3% (24.9-48.6) and was significantly greater (p < 0.001) than the discordance of the prenatal supratentorial brain (13.6% [5.6-18]), cerebellum volume (21.7% [9.5-30.8]). Further neurodevelopmental outcome evaluation found no significant difference between the AGA twin and the SGA twin. CONCLUSION: In discordant twins, the smaller twin showed a "brain-preserving effect," which in our study was not associated with a worse neurodevelopmental outcome. The use of MRI in such cases may aid in decision-making and parental consultation. KEY POINTS: ⢠Weight discordance at birth was significantly greater compared to intrauterine brain volume discordance measured by 3D MRI. ⢠Small-for-gestational-age (SGA) fetuses preserve brain development. ⢠In highly discordant twins, there was no long-term difference in neurodevelopmental outcome at a mean age of 4.9 years.

OBJECTIVE: To determine the rate of and risk factors for fetal and neonatal brain lesions following laser ablation for twin-to-twin transfusion syndrome (TTTS). METHODS: A retrospective cohort study of 83 women with monochorionic twin pregnancies who underwent ablation for TTTS at a single tertiary hospital. Post-laser survivors were followed-up with fetal neurosonogram every 2 weeks and fetal brain MRI at 28-32 weeks of gestation; post-natal brain imaging included neurosonogram. Cases with pre- and post-natal brain lesions were compared to those without. RESULTS: 153 fetuses survived the immediate post-laser period and underwent brain imaging. Of these, 17 (11.11%) exhibited brain lesions on prenatal imaging studies, and 36 (32.4%) on post-natal ultrasound. Later gestational age (GA) at the time of ablation (23.0 vs. 21.4 weeks, p = 0.0244), post-laser twin-anemia-polycythemia-sequence (TAPS) (29.41% vs. 9.56%, p = 0.035) and birthweight discordancy (30% vs. 9%, p = 0.0025) were associated with prenatal brain lesions. Earlier GA at delivery (31.0 weeks vs. 32.2, p = 0.0002) and post-laser TAPS (25% vs. 9.33%, p = 0.038) were associated with post-natal brain lesions. CONCLUSIONS: Survivors of ablation for TTTS are at risk for brain lesions, which can be detected prenatally. Incorporation of neurosonogram and fetal brain MRI into the routine surveillance of such pregnancies should be considered.

OBJECTIVES: Fetal brain non-dilated ventricular asymmetry (NDVA) is a common finding on prenatal ultrasound exams. However, the optimal prenatal management in these cases remains unknown. We aimed to evaluate the benefit of prenatal genetic and magnetic resonance imaging (MRI) exams performed in cases of fetal NDVA detected on ultrasound. METHODS: A historical cohort study from a tertiary medical center. Singleton pregnancies with fetal brain NDVA diagnosed on ultrasound were included. We defined ventricular asymmetry as a difference of ≥2.0 mm between the lateral ventricles and ventricular dilation as ventricular width of >10.0 mm. Outcomes were evaluated with genetic exams (karyotype and chromosomal microarray analysis [CMA]) and fetal brain MRI. RESULTS: During the study period, there were 145 cases diagnosed with NDVA on ultrasound that comprised the cohort study. The rate of abnormal karyotype was 1.8% (1/56) and of abnormal CMA was 10% (3/30). The rate of minor additional CNS findings did not differ between ultrasound and MRI (3.4 versus 2.8%, respectively, p = .74). No major additional fetal brain findings were detected on MRI performed after ultrasound. CONCLUSIONS: In cases diagnosed with NDVA on ultrasound, no significant additional anomalies were detected on fetal brain MRI. The rate of abnormal genetic tests was relatively high and warrants further studies.

Anticipating the need for a COVID-19 treatment centre in Israel, a designated facility was established at Sheba Medical Center-a quaternary referral centre. The goals were diagnosis and treatment of patients with COVID-19 while protecting patients and staff from infection and ensuring operational continuity and treatment of patients with non-COVID. Options considered included adaptation of existing wards, building a tented facility and converting a non-medical structure. The option chosen was a non-medical structure converted to a hospitalisation facility suited for COVID-19 with appropriate logistic and organisational adaptations. Operational principles included patient isolation, unidirectional workflow from clean to contaminated zones and minimising direct contact between patients and caregivers using personal protection equipment (PPE) and a multimodal telemedicine system. The ED was modified to enable triage and treatment of patients with COVID-19 while maintaining a COVID-19-free environment in the main campus. This system enabled treatment of patients with COVID-19 while maintaining staff safety and conserving the operational continuity and the ability to continue delivery of treatment to patients with non-COVID-19.

OBJECTIVES: The aim of this study was to evaluate the role of fetal magnetic resonance imaging (MRI) as a complement to ultrasound (US) in the prenatal diagnosis of craniofacial anomalies. METHODS: A historical cohort study including all pregnant women who were referred for fetal MRI because of antenatal diagnosis of craniofacial anomalies on screening US. Prenatal diagnostic US, MRI, and postnatal diagnosis were compared for consistencies and discrepancies. RESULTS: Forty-five pregnant women with 73 suspected fetal craniofacial anomalies diagnosed by US underwent MRI. In 40 out of 73 anomalies (54.8%), US and MRI findings were in complete agreement with postnatal diagnoses. MRI correctly ruled out the diagnosis of 24 anomalies suspected on US and diagnosed four additional pathologies that were not demonstrated by US. Out of the 85 anomalies (suspected by imaging or confirmed postnatally), confident diagnosis could be made by MRI in 68 anomalies (80%), not diagnosed in 10 (11.8%), and over-diagnosed in seven (8.2%). By US, confident diagnosis could be made in 44 anomalies (51.8%), not diagnosed in 11 (12.9%), and over-diagnosed in 30 (35.3%). CONCLUSION: MRI is valuable in the antenatal evaluation of fetal craniofacial anomalies and may be useful as an adjunct to US in the prenatal work-up of craniofacial anomalies.

BACKGROUND: Channeling medical resources for coronavirus disease-2019 (COVID-19) management can potentially endanger routine healthcare practices. As a preventive measure, a department of obstetrics and gynecology in Israel constructed a separate, designated complex for its COVID-19-exposed patients. OBJECTIVES: To evaluate the effect of the COVID-19 pandemic infection control measures on obstetric care in the obstetrical emergency department and delivery unit. METHODS: The authors collected data retrospectively from February 2020 to March 2020 and compared it to data of a parallel period in 2019. RESULTS: From 1 February 2020 to 28 March 2020, 3897 women were referred to the emergency department (ED), compared to 4067 the previous year. Mean duration of treatment until decision and referral indications did not differ between 2020 and 2019 (207 vs. 220 minutes, P = 0.26; urgent referrals 58.8% vs. 59.2%, P = 0.83). A per-week comparison showed a significant reduction in ED referrals only in the last week of the period (337 [2020] vs. 515 [2019], P < 0.001). The proportion of women admitted to the delivery unit in active labor was significantly higher in the last three weeks (39.1% vs. 28.2%, P = 0.005). During February and March 2020, 1666 women delivered, compared to 1654 during February and March 2019. The proportion of types and modes of delivery did not differ. In a per-week comparison, the number of deliveries did not differ (mean 208 vs. 206, P = 0.88). CONCLUSIONS: With timely preparation and proper management, negative impact of COVID-19 can be reduced in obstetrical emergency departments.

BACKGROUND: Fetal ventriculomegaly is one of the more common fetal anomalies detected during prenatal screening. OBJECTIVES: To assess the rate of genetic aberrations as the cause for ventriculomegaly in these fetuses. METHODS: A historic cohort study was conducted on 164 fetuses with sonographic diagnosis of ventriculomegaly. All cases were analyzed for karyotype and 41 cases were further analyzed by chromosomal microarray (CMA). The study group was subdivided by laterality, severity, and whether the ventriculomegaly was an isolated finding or not. Subgroups were compared and the study group was compared to a control group of 209 fetuses. RESULTS: Karyotype aberrations were more common among fetuses with ventriculomegaly (6.6%) compared to controls (0%, P < 0.001). CMA aberrations were more common in the non-isolated ventriculomegaly cases (24.1%) compared to controls (6.2%, P = 0.031). The rate of genetic aberrations was not associated with the degree of dilatation or laterality. CONCLUSIONS: It is equivocal whether CMA testing should be conducted on every amniotic fluid sample taken from fetuses with isolated ventriculomegaly. However, if more anomalies are detected during an anatomical survey, CMA analysis should be conducted to decrease oversights of genetic diagnoses.

BACKGROUND: Congenital heart defects (CHD) may be associated with neurodevelopmental abnormalities mainly due to brain hypoperfusion. This defect is attributed to the major cardiac operations these children underwent, but also to hemodynamic instability during fetal life. Advances in imaging techniques have identified changes in brain magnetic resonance imaging (MRI)in children with CHD. OBJECTIVES: To examine the correlation between CHD and brain injury using fetal brain MRI. METHODS: We evaluated 46 fetuses diagnosed with CHD who underwent brain MRI. CHD was classified according to in situs anomalies, 4 chamber view (4CV), outflow tracts, arches, and veins as well as cyanotic or complex CHD. We compared MRI results of different classes of CHD and CHD fetuses to a control group of 113 healthy brain MRI examinations. RESULTS: No significant differences were found in brain pathologies among different classifications of CHD. The anteroposterior percentile of the vermis was significantly smaller in fetuses with abnormal 4CV. A significantly higher biparietal diameter was found in fetuses with abnormal arches. A significantly smaller transcerebellar diameter was found in fetuses with abnormal veins. Compared to the control group, significant differences were found in overall brain pathology in cortex abnormalities and in extra axial findings in the study group. Significantly higher rates of overall brain pathologies, ventricle pathologies, cortex pathologies, and biometrical parameters were found in the cyanotic group compared to the complex group and to the control group. CONCLUSIONS: Fetuses with CHD demonstrate findings in brain MRI that suggest an in utero pathogenesis of the neurological and cognitive anomalies found during child development.

BACKGROUND: In February 2020, the World Health Organisation designated the name COVID-19 for a clinical condition caused by a virus identified as a cause for a cluster of pneumonia cases in Wuhan, China. The virus subsequently spread worldwide, causing havoc to medical systems and paralyzing global economies. The first COVID-19 patient in Israel was diagnosed on 27 February 2020. OBJECTIVES: To present our findings and experiences as the first and largest center for COVID-19 patients in Israel. METHODS: The current analysis included all COVID-19 patients treated in Sheba Medical Center from February 2020 to April 2020. Clinical, laboratory, and epidemiological data gathered during their hospitalization are presented. RESULTS: Our 162 patient cohort included mostly adult (mean age of 52 ± 20 years) males (65%). Patients classified as severe COVID-19 were significantly older and had higher prevalence of arterial hypertension and diabetes. They also had significantly higher white blood cell counts, absolute neutrophil counts, and lactate dehydrogenase. Low folic acid blood levels were more common amongst severe patients (18.2 vs. 12.9 vs. 9.8, P = 0.014). The rate of immune compromised patients (12%) in our cohort was also higher than in the general population. The rate of deterioration from moderate to severe disease was high: 9% necessitated non-invasive oxygenation and 15% were intubated and mechanically ventilated. The mortality rate was 3.1. CONCLUSIONS: COVID-19 patients present a challenge for healthcare professionals and the whole medical system. We hope our findings will assist other providers and institutions in their care for these patients.

The use of mobile phone for medical purposes is rapidly expanding as the number of medical applications rise. Studies show improvement of patient management and communication between medical team members using instant messaging applications. There are currently several smartphone applications routinely used by doctors and nurses. WhatsApp is by far the most common, however, it has several limitations when it comes to medical confidentiality. The aim of this paper is to introduce "Siilo" as an alternative secure messaging application and its advantages in the medical field, specifically in obstetrics. The typical course of consultation for an abnormal fetal finding is very long, cumbersome, frustrating and depends a lot on the patient, whereas, via Siilo the process is fast, efficient, depends more on the medical caregivers and helps ensuring minimum lost to follow-up. This paper demonstrates for the first time the utility of the use of Siilo application in medical management.

OBJECTIVE: Data regarding the neurodevelopmental outcome of fetal short corpus callosum (CC) diagnosed according to standard reference charts is scarce. The purpose of this study was to assess whether the finding is related to neurodevelopmental delay, and to examine reclassification to normal fetal CC length using CC length/EFW ratio. METHOD: Historical prospective cohort study including pregnant women who were referred for fetal neurosonogram due to abnormal CC. Short CC was defined below the 5th percentile according to reference charts. Twenty cases were included in the study group and compared with a control group of 59 normal cases. The patients in the study group were divided into two groups according to CC length/EFW ratio. Children's neurodevelopment was assessed using the Vineland Adaptive Behavior Scale (VABS). RESULTS: VABS scores were within normal range in 90% of the cases. There was no significant statistical difference between the study group and the control group. In addition, there was no statistically significant difference between fetuses reclassified as normal callosal length according to CC length/EFW ratio in comparison to the control group. CONCLUSION: The neurodevelopmental outcome of fetuses with diagnosed short CC did not differ from the neurodevelopment of normal fetuses in the control group.

OBJECTIVE: To evaluate the added value of fetal MRI to ultrasound in detecting and specifying callosal anomalies, and its impact on clinical decision making. METHODS: Fetuses with a sonographic diagnosis of an anomalous corpus callosum (CC) who underwent a subsequent fetal brain MRI between 2010 and 2015 were retrospectively evaluated and classified according to the severity of the findings. The findings detected on ultrasound were compared to those detected on MRI. An analysis was performed to assess whether fetal MRI altered the group classification, and thus the management of these pregnancies. RESULTS: 78 women were recruited following sonographic diagnoses of either complete or partial callosal agenesis, short, thin or thick CC. Normal MRI studies were obtained inµ19 cases (24â%). Among these, all children available for follow-up received an adequate adaptive score in their Vineland II adaptive behavior scale assessment. Analysis of the concordance between US and MRI demonstrated a substantial level of agreement for complete callosal agenesis (kappa: 0.742), moderate agreement for thin CC (kappa: 0.418) and fair agreement for all other callosal anomalies. Comparison between US and MRI-based mild/severe findings classifications revealed that MRI contributed to a change in the management for 28 fetuses (35.9â%), mostly (25 fetuses, 32.1â%) in favor of pregnancy preservation. CONCLUSION: Fetal MRI effectively detects callosal anomalies and enables satisfactory validation of the presence or absence of callosal anomalies identified by ultrasound and adds valuable data that improves clinical decision making.

OBJECTIVE: Data regarding the neurodevelopmental outcome of children diagnosed in utero with isolated ventriculomegaly (IVM) are limited and principally founded on ultrasound-based studies. Here, we endeavored to assess the outcome of such cases in a large-scale, magnetic resonance imaging (MRI)-based study. METHODS: We conducted a study on 133 cases of IVM with a documented fetal brain MRI scan. Children were assessed at ages 18 to 36 months by using the Vineland Adaptive Behavior Scales (VABS). RESULTS: Vineland Adaptive Behavior Scales scores were within normal range. There was no significant difference between VABS score in symmetric versus asymmetric IVM (101.7 vs. 101.6, respectively; p = 0.94), and the VABS score of mild IVM was comparable with that of moderate IVM (101.8 vs. 101; p = 0.8). Only five cases (3.8%) were found to have an abnormal score (<85). There was no significant difference in the rate of abnormal scores between mild and moderate IVM (2.8% vs. 8.3%, respectively; p = 0.22). CONCLUSION: In cases of isolated ventriculomegaly, a normal neurodevelopmental outcome is to be expected; moreover, the outcome does not appear to be affected by the severity or asymmetry of the ventriculomegaly. Thus, following a meticulous workup, patients can be given reassuring counseling regarding the child's prognosis. © 2017 John Wiley & Sons, Ltd.
