Severe fetal ventriculomegaly: Fetal morbidity and mortality, caesarean delivery rates and obstetrical challenges in a large prospective cohort.

INTRODUCTION: Severe fetal ventriculomegaly (VM) is defined as an enlargement of the atria of the lateral cerebral ventricles (Vp) of greater than 15 mm. While it is well established that it confers significant risk of morbidity and mortality to the neonate, there is limited information pertaining to the caesarean delivery rates and the obstetric management of these complex cases. The aim of this study was twofold: firstly, to determine survival rates in fetuses with severe VM, and secondly to determine the caesarean delivery rates in continuing pregnancies. We explore the obstetric challenges associated with these difficult cases. METHODS: This was a prospective observational study of patients with antenatal severe VM, attending the Department of Fetal Medicine, National Maternity Hospital, Dublin, Ireland, from 1st January 2011 to 31st July 2020. Data were obtained from the hospital database and those with severe VM (Vp > 15 mm) were identified. The rates of chromosomal abnormalities, the survival rates and the caesarean delivery (CD) rates for the overall group were then determined. The data were then further sub-divided into two groups: 1. Vp < 20 mm and 2. Vp > 20 mm, and the results compared. Statistical analysis was performed using the Chi-Square test. RESULTS: A total of N = 95 pregnancies with severe VM were included for analysis, of which additional structural abnormalities on ultrasound were apparent in 67/95 (70.5%) and 28/95 (29.5%) had isolated severe VM. Chromosomal abnormalities were diagnosed in 15/95 (15.8%) of cases, with (2/28) 7.1% in the isolated SVM group versus (13/67) 19.4% in the non-isolated SVM group. The overall survival rate (excluding TOP) was 53/74 (71.6%), with 20/23 (86.9%) in the isolated SVM group. The overall CD rate was 47/72 (65.3%), which was significantly higher than the CD for the hospital during the same time period of 25.4% (P < 0.01). The data were subdivided into Vp < 20 and Vp > 20 and those with a Vp > 20 had higher rates of additional intracranial findings on ultrasound (Vp < 20 13/41 (31.7%) versus Vp > 20 32/54 (59.3%) (P < 0.05)) and macrocrania (Vp < 20 14/41 (34.1%) versus Vp > 20 35/54 (64.8%) (P < 0.05)). No significant difference was observed in the overall survival or CD rates between the two groups. CONCLUSION: In conclusion this study reports significant fetal morbidity and mortality with severe VM with high CD rates observed in this cohort. Significant challenges exist in relation to the obstetric management and counseling of parents regarding an often uncertain neonatal prognosis. In continuing pregnancies with significant macrocrania delivery plans should be individualized to improve neonatal outcomes where possible and minimize harm to the mother.

Fetal magnetic resonance imaging at 3 Tesla - the European experience.

BACKGROUND: The Fetal Imaging Taskforce was established in 2018 by the European Society of Paediatric Radiology. The first survey on European practice of fetal imaging published in 2020 revealed that 30% of fetal magnetic resonance imaging (MRI) is performed at 3 tesla (T). The purpose of this second survey was to identify the impact of 3-T fetal MRI with an emphasis on image quality, diagnostic yield, and technical challenges and artifacts at higher field strengths. OBJECTIVE: To describe the prenatal imaging practice at 3-T MRI units in various centres in Europe and to prepare recommendations on behalf of the Fetal Imaging Taskforce. MATERIALS AND METHODS: A survey was sent to all members performing 3-T fetal MRI. Questions included practitioner experience, magnet brand, protocols, counselling, artifacts and benefits of imaging at higher field strengths. RESULTS: Twenty-seven centres replied and reported improved spatial resolution and improved signal-to-noise ratio when performing fetal MRI at 3 T. Shading and banding artifacts and susceptibility to motion artifacts were common problems identified by practitioners at the higher field strength. For all neurological indications, practitioners reported a benefit of imaging at 3 T, most marked for posterior fossa evaluation and parenchymal lesions. CONCLUSION: The use of 3-T magnets in fetal MRI has improved the availability and quality of advanced imaging sequences and allowed for better anatomical evaluation. There remain significant challenges to minimize the impact of artifacts on image quality. This paper includes guidelines for clinical practice and imaging at 3 T.

Fetal ultrasound and magnetic resonance imaging: a primer on how to interpret prenatal lung lesions.

Fetal lung lesions include common lesions such as congenital pulmonary airway malformation (CPAM), bronchopulmonary sequestration (BPS) and combined CPAM-BPS hybrid lesions, as well as less common entities including congenital lobar emphysema/obstruction, bronchial atresia, bronchogenic cysts and rare malignant pulmonary lesions such as pleuropulmonary blastoma. Fetal lung lesions occur in approximately 1 in 15,000 live births and are thought to arise from a spectrum of abnormalities related to airway obstruction and malformation, with the lesion type depending on the timing of insult, level of bronchial tree involvement, and severity of obstruction. Lesions vary from small and asymptomatic to large and symptomatic with significant mass effect on surrounding structures. Accurate diagnosis and characterization of these anomalies is crucial for guiding patient counseling as well as perinatal and postnatal management. The goal of this review is to provide an overview of normal fetal lung appearance and imaging features of common and uncommon lesions on both ultrasound and MR imaging, and to discuss key aspects in reporting and evaluating the severity of these lesions.

Computed tomography and upper gastrointestinal series findings of esophageal bronchi in infants.

BACKGROUND: Esophageal bronchus is a rare form of communicating bronchopulmonary foregut malformation and a rare but important cause of an opaque hemithorax on chest radiography. A higher incidence of esophageal bronchus is associated with esophageal atresia, tracheo-esophageal fistula (TEF) and VACTERL (vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, and limb abnormalities) association. In the presence of these conditions, the pediatric radiologist may be the first to consider the diagnosis of esophageal bronchus or esophageal lung. OBJECTIVE: To describe the imaging features in five children with esophageal bronchus. MATERIALS AND METHODS: We reviewed hospital records and teaching files at two large pediatric tertiary referral centers over the 24-year period from January 1992 to January 2016. We reviewed all imaging studies and tabulated findings on radiography, fluoroscopic upper gastrointestinal (GI) series and CT. We then described the imaging features of esophageal bronchi with emphasis on CT and upper GI findings in four infants and one toddler. RESULTS: Three cases were identified from one institution (cases 2, 3, 4) and two from another (cases 1, 5). All five cases occurred in association with other midline malformations: four of the five had VACTERL association and three of the five had esophageal atresia and TEF. CONCLUSION: Lung opacification, ipsilateral mediastinal shift, and an abnormal carina and anomalous vascular anatomy suggest an esophageal bronchus or an esophageal lung on CT. While esophageal bronchus is a rare cause of an opaque hemithorax, CT and upper GI imaging play key roles in its diagnosis. Associations with esophageal atresia with tracheo-esophageal fistula and VACTERL association are particularly pertinent. Early diagnosis of esophageal bronchus might prevent complications such as aspiration and infection, which can allow for parenchymal sparing surgery as opposed to pneumonectomy.

Imaging in the diagnosis of pediatric urolithiasis.

Pediatric urolithiasis is an important and increasingly prevalent cause of pediatric morbidity and hospital admission. Ultrasound (US) is the recommended primary imaging modality for suspected urolithiasis in children. There is, however, widespread use of CT as a first-line study for abdominal pain in many institutions involved in pediatric care. The objective of this review is to outline state-of-the-art imaging modalities and methods for diagnosing urolithiasis in children. The pediatric radiologist plays a key role in ensuring that the appropriate imaging modality is performed in the setting of suspected pediatric urolithiasis. Our proposed imaging algorithm starts with US, and describes the optimal technique and indications for the use of CT. We emphasize the importance of improved communication with a greater collaborative approach between pediatric and general radiology departments so children undergo the appropriate imaging evaluation.

Intrarenal Reflux: Diagnosis at Contrast-Enhanced Voiding Urosonography.

Vesicoureteral reflux (VUR) is a childhood condition that is usually diagnosed by fluoroscopic voiding cystourethrography (VCUG). Intrarenal reflux (IRR) of infected urine is believed to play an important role in the pathogenesis of reflux-associated pyelonephritis and subsequent parenchymal scarring and is traditionally depicted by fluoroscopic VCUG. This case series describes the phenomenon of IRR occurring in association with VUR in 4 children as depicted by contrast-enhanced voiding urosonography. The ability of contrast-enhanced voiding urosonography to show IRR when it occurs in conjunction with VUR compares favorably to that of fluoroscopic VCUG.

Residual intravesical iodinated contrast: a potential cause of false-negative reflux study at contrast-enhanced voiding urosonography.

A 9-month-old girl underwent conventional cyclic voiding cystourethrography (VCUG) followed immediately by cyclic contrast-enhanced voiding urosonography (ceVUS). Although the VCUG showed unilateral grade II reflux, the ceVUS showed no reflux. Images from the ceVUS showed posterior dependent layering of the denser iodinated contrast in the bladder. This layering likely prevented reflux of US microbubbles resulting in a false-negative ceVUS. To our knowledge, this potential pitfall has not yet been reported.

Acute nontraumatic spinal intradural hematoma in a patient on warfarin.

BACKGROUND: Nontraumatic spinal intradural extramedullary hematomas are extremely rare. When they occur, they can rapidly lead to spinal cord or cauda equina compression and have devastating consequences. OBJECTIVE: The aim here was to report a case of this rare phenomenon and discuss the etiology, imaging, management, and outcome of intradural hematomas. CASE REPORT: We describe the case of a 76-year-old man on warfarin therapy who presented with severe lower back pain and flaccid paraparesis. Blood tests revealed an international normalized ratio of 6.0. A magnetic resonance imaging result suggested an intradural hematoma extending from L1 to L4 and compressing the spinal cord and cauda equina. Emergency surgical decompression revealed an extensive intradural extramedullary hematoma, which was evacuated. The patient showed only minor neurologic improvement 6 months postoperatively. CONCLUSIONS: Coagulopathy-induced spinal hemorrhage should be included in the differential diagnosis for patients presenting with signs of acute spinal cord compression.

How to apply evidence-based practice to the use of artificial intelligence in radiology (EBRAI) using the data algorithm training output (DATO) method.

OBJECTIVE: As the number of radiology artificial intelligence (AI) papers increases, there are new challenges for reviewing the AI literature as well as differences to be aware of, for those familiar with the clinical radiology literature. We aim to introduce a tool to aid in this process. METHODS: In evidence-based practise (EBP), you must Ask, Search, Appraise, Apply and Evaluate to come to an evidence-based decision. The bottom-up evidence-based radiology (EBR) method allows for a systematic way of choosing the correct radiological investigation or treatment. Just as the population intervention comparison outcome (PICO) method is an established means of asking an answerable question; herein, we introduce the data algorithm training output (DATO) method to complement PICO by considering Data, Algorithm, Training and Output in the use of AI to answer the question. RESULTS: We illustrate the DATO method with a worked example concerning bone age assessment from skeletal radiographs. After a systematic search, 17 bone age estimation papers (5 of which externally validated their results) were appraised. The paper with the best DATO metrics found that an ensemble model combining uncorrelated, high performing simple models should achieve error rates comparable to human performance. CONCLUSION: Considering DATO in the application of EBR to AI is a simple systematic approach to this potentially daunting subject. ADVANCES IN KNOWLEDGE: The growth of AI in radiology means that radiologists and related professionals now need to be able to review not only clinical radiological literature but also research using AI methods. Considering Data, Algorithm, Training and Output in the application of EBR to AI is a simple systematic approach to this potentially daunting subject.

An unusual case of a giant fetal facial tumour and review of the literature.

We present the case of a pregnant 32-year-old woman who presented with a giant fetal facial tumour at 22 weeks. The mass, initially 4 × 3.5 × 3 cm in size, was largely cystic with a small solid component. It subsequently increased to 9 × 9 × 10 cm. Significant compression effects on the fetal orbit, temple and infratemporal fossa, with potential compression of the optic nerve, were noted on ultrasound and MRI. The cyst required drainage twice in the pregnancy: firstly to reduce the compression effects and secondly to facilitate caesarean delivery. Postnatally, the baby had significant compression and displacement of the craniofacial skeleton from the mass effect. Postnatal histology revealed a diagnosis of a teratoma. This case highlights the complexities and challenges surrounding the diagnosis and management of a giant fetal facial tumour.

Mid-Arm Point in PAEDiatrics (MAPPAED): An effective procedural aid for safe pleural decompression in trauma.

OBJECTIVE: Life-threatening thoracic trauma requires emergency pleural decompression and thoracostomy and chest drain insertion are core trauma procedures. Reliably determining a safe site for pleural decompression in children can be challenging. We assessed whether the Mid-Arm Point (MAP) technique, a procedural aid proposed for use with injured adults, would also identify a safe site for pleural decompression in children. METHODS: Children (0-18 years) attending four EDs were prospectively recruited. The MAP technique was performed, and chest wall skin marked bilaterally at the level of the MAP; no pleural decompression was performed. Radio-opaque markers were placed over the MAP-determined skin marks and corresponding intercostal space (ICS) reported using chest X-ray. RESULTS: A total of 392 children participated, and 712 markers sited using the MAP technique were analysed. Eighty-three percentage of markers were sited within the 'safe zone' for pleural decompression (4th to 6th ICSs). When sited outside the 'safe zone', MAP-determined markers were typically too caudal. However, if the site for pleural decompression was transposed one ICS cranially in children ≥4 years, the MAP technique performance improved significantly with 91% within the 'safe zone'. CONCLUSIONS: The MAP technique reliably determines a safe site for pleural decompression in children, albeit with an age-based adjustment, the Mid-Arm Point in PAEDiatrics (MAPPAED) rule: 'in children aged ≥4 years, use the MAP and go up one ICS to hit the safe zone. In children <4 years, use the MAP.' When together with this rule, the MAP technique will identify a site within the 'safe zone' in 9 out of 10 children.

Placenta accreta spectrum ultrasound stage and fetal growth.

OBJECTIVE: to evaluate fetal growth in pregnancies complicated by placenta accreta spectrum (PAS) and to compare fetal growth between cases stratified by ultrasound stage of PAS. METHODS: This was a prospective multicenter cohort study of women diagnosed with PAS between January 2018 and December 2021. We grouped participants into cases by ultrasound stage (PAS stage 1-3) and controls (PAS0). Fetal growth centiles at three timepoints with median gestational ages of 21 ± 1 weeks (interquartile range [IQR], 20 ± 1-22 ± 0 weeks), 28 ± 0 weeks (IQR, 27 ± 0-28 ± 5 weeks), and 33 ± 0 weeks (IQR, 32 ± 1-34 ± 0 weeks) and birth weight centiles were compared between cases and controls and between those with PAS stratified by ultrasound stage. RESULTS: A total of 53 women met inclusion criteria, with a mean age of 37 years (standard deviation, ±4.0 years) and body mass index of 27 kg/m2 (standard deviation, ±5.8 kg/m2 ). Median (IQR) fetal weight centiles were around the 50th centile at each timepoint, with no difference between groups. The incidence of small for gestational age (birth weight ≤ 10th percentile) and large for gestational age (birth weight ≥ 90th percentile) was 11.3% (n = 6) and 15.1% (n = 8), respectively, with no differences by ultrasound stage. The median birth weight centile was 64 (IQR, 26-85), with no differences between cases and controls or by ultrasound stage. CONCLUSIONS: In our cohort, a diagnosis of PAS was not associated with fetal growth restriction.

International Consensus Statement on the Radiological Screening of Contact Children in the Context of Suspected Child Physical Abuse.

Importance: Physical abuse is a common but preventable cause of long-term childhood morbidity and mortality. Despite the strong association between abuse in an index child and abuse in contact children, there is no guidance outlining how to screen the latter, significantly more vulnerable group, for abusive injuries. Consequently, the radiological assessment of contact children is often omitted, or variably performed, allowing occult injuries to go undetected and increasing the risk of further abuse. Objective: To report an evidence-based and consensus-derived set of best practices for the radiological screening of contact children in the context of suspected child physical abuse. Evidence Review: This consensus statement is supported by a systematic review of the literature and the clinical opinion of an internationally recognized group of 26 experts. The modified Delphi consensus process comprised 3 meetings of the International Consensus Group on Contact Screening in Suspected Child Physical Abuse held between February and June 2021. Findings: Contacts are defined as the asymptomatic siblings, cohabiting children, or children under the same care as an index child with suspected child physical abuse. All contact children should undergo a thorough physical examination and a history elicited prior to imaging. Contact children younger than 12 months should have neuroimaging, the preferred modality for which is magnetic resonance imaging, and skeletal survey. Contact children aged 12 to 24 months should undergo skeletal survey. No routine imaging is indicated in asymptomatic children older than 24 months. Follow-up skeletal survey with limited views should be performed if abnormal or equivocal at presentation. Contacts with positive findings should be investigated as an index child. Conclusions and Relevance: This Special Communication reports consensus recommendations for the radiological screening of contact children in the context of suspected child physical abuse, establishing a recognized baseline for the stringent evaluation of these at-risk children and providing clinicians with a more resilient platform from which to advocate for them.

A pilot study of burnout and long covid in senior specialist doctors.

BACKGROUND: Covid-19 has placed unprecedented demand on healthcare systems and on healthcare professionals. There have been concerns about the risk of distress, moral injury and burnout among healthcare professionals, especially doctors. AIM: To assess the effect of the ongoing Covid-19 pandemic on Irish doctors by investigating the incidence of burnout and long covid among senior medical staff in Ireland. METHODS: This is a cross-sectional pilot study of the prevalence of burnout and long covid among senior physicians. A survey was sent by email to members of the Irish Hospital Consultant's Association. The survey included measures of mental and physical health and the 2-item Maslach Burnout Scale (MBS-2). The study explored the experience of delivering health care in the context of a pandemic and experience of the long covid syndrome. RESULTS: A total of 114 responses were received. Three-quarters 77% (N = 88) screened positive for burnout on the MBS, with mean score of 5.6 (SD3.3), nearly double the cut-off for burnout. Nearly two-thirds (64%, n = 72) reported that Covid-19 has had an adverse effect on their mental health. One-quarter reported that they or colleagues had experience of 'long-covid' secondary to the virus. CONCLUSION: More comprehensive evaluation of the effect of the pandemic on front-line staff is needed to identify the extent of the problem and the factors which contribute to it. This will inform measures to mitigate these effects.

Prenatal findings and associated survival rates in fetal ventriculomegaly: A prospective observational study.

OBJECTIVES: Fetal ventriculomegaly is associated with varying degrees of genetic and structural abnormalities. The objective was to present the experience of fetal ventriculomegaly in a large European center in relation to: 1. grade of ventriculomegaly; 2. additional chromosomal/structural abnormalities; and 3. perinatal survival rates. METHODS: This was a prospective observational study of patients referred with fetal ventriculomegaly from January 2011 to July 2020. Data were obtained from the hospital database and analyzed to determine the rate of isolated ventriculomegaly, associated structural abnormalities, chromosomal/genetic abnormalities, and survival rates. Data were stratified into three groups; mild (Vp = 10-12 mm), moderate (Vp = 13-15 mm) and severe (Vp > 15 mm) ventriculomegaly. RESULTS: There were 213 fetuses included for analysis. Of these 42.7% had mild ventriculomegaly, 44.6% severe and 12.7% had moderate ventriculomegaly. Initial ultrasound assessment reported isolated ventriculomegaly in 45.5% fetuses, with additional structural abnormalities in 54.5%. The rate of chromosomal/genetic abnormalities was high,16.4%. After all investigations, the true rate of isolated VM was 36.1%. The overall survival was 85.6%. Survival was higher for those with isolated VM across all groups (P < 0.05). CONCLUSION: Ventriculomegaly is a complex condition and patients should be counselled that even with apparently isolated VM, there remains the possibility of additional genetic and/or structural problems being diagnosed in up to 10% of fetuses.

A multidisciplinary fetal neurosurgical service-5 years of fetal outcomes from a national referral centre.

BACKGROUND: A specialist fetal neurosurgical clinic was set up in order to improve patient care in a tertiary referral fetal medicine centre. The clinic provides a targeted clinical service for women diagnosed with fetal neurological abnormalities. The service consists of fetal MRI, fetal ultrasound and joint assessment and counselling from neurosurgery and fetal medicine teams. AIMS: We aimed to review this service that provides MDT expertise directly to parents and record the cases and pregnancy outcomes involved. METHODS: This is a prospective study of clinic data from Jan 2013 to Dec 2017. Information includes ultrasound scan findings, MRI results, karyotype results and pregnancy outcome data including post mortem results and data from the paediatric neurosurgery service at the affiliated children's hospital. RESULTS: From 2013 to 2017, there were 1852 major fetal anomalies diagnosed antenatally at the tertiary referral fetal medicine service and n = 306/1852 [16%] were primarily neurological in origin. The neurosurgical clinic reviewed 125 patients since 2013. The most common reasons for referral were spina bifida, n = 60 [48%] and isolated ventriculomegaly n = 43 [34%]. Other reasons for referral include agenesis of the corpus callosum n = 4 [3%], encephalocoele n = 5 [4%] and intracranial mass lesions n = 3 [2.4%]. Cases with borderline ventriculomegaly and cases with known chromosomal or genetic abnormalities were not typically referred to the clinic. Full outcome data were available on 110 of 125 women seen. Thirty-two women [29%] underwent invasive testing and 14 women [12.7%] had a termination of pregnancy. CONCLUSION: Multidisciplinary antenatal counselling supported with in utero MRI provides families with optimum information to inform them of likely neonatal outcome.

Relationship Between MRI Scoring Systems and Neurodevelopmental Outcome at Two Years in Infants With Neonatal Encephalopathy.

BACKGROUND: Magnetic resonance imaging (MRI) scoring systems are used in the neonatal period to predict outcome in infants with neonatal encephalopathy. Our aim was to assess the relationship between three MRI scores and neurodevelopmental outcome assessed using Bayley Scales of Infant and Toddler Development, third edition (Bayley-III), at two years in infants with neonatal encephalopathy. METHODS: Term-born neonates with evidence of perinatal asphyxia born between 2011 and 2015 were retrospectively reviewed. MRI scanning was performed within the first two weeks of life and scored using Barkovich, National Institute of Child Health and Human Development (NICHD) Neonatal Research Network (NRN), and Weeke systems by a single assessor blinded to the infants clinical course. Neurodevelopmental outcome was assessed using composite scores on the Bayley-III at two years. Multiple linear regression analyses were used to assess the association between MRI scores and Bayley-III composite scores, with postmenstrual age at scan and sex included as covariates. RESULTS: Of the 135 recruited infants, 90 infants underwent MRI, and of these, 66 returned for follow-up. MRI abnormalities were detected with the highest frequency using the Weeke score (Barkovich 40%, NICHD NRN 50%, Weeke 77%). The inter-rater agreement was good for the Barkovich score and excellent for NICHD NRN and Weeke scores. There was a significant association between Barkovich, NICHD NRN, and Weeke scores and Bayley-III cognitive and motor scores. Only the Weeke score was associated with Bayley-III language scores. CONCLUSIONS: Our findings confirm the predictive value of existing MRI scoring systems for cognitive and motor outcome and suggest that more detailed scoring systems have predictive value for language outcome.

Comparing three-dimensional models of placenta accreta spectrum with surgical findings.

OBJECTIVE: Placenta accreta spectrum (PAS) is associated with significant maternal morbidity mainly related to blood loss. Pre-operative planning is aided by antenatal ultrasound and magnetic resonance imaging. We sought to assess whether three-dimensional (3D) models from MR images were accurate when compared with surgical and pathological findings. METHODS: Digital Imaging and Communications in Medicine files containing MR images with varying severity of PAS (n = 4) were modeled using 3D Slicer. Placenta, bladder, and myometrial defects were modeled. Myometrial defects at three different uterine locations were included-anterior, lateral and inferior. 3D models were used to identify the relationship between the myometrial defect and the internal cervical os. Findings were validated in a larger series of PAS cases (n = 14) where patterns of invasion were compared with estimated blood loss and distance from defect to the internal os. RESULTS: The defect illustrated in the four 3D models correlates to both surgical and pathological findings in terms of depth and pattern of invasion, location of defect, bladder involvement. Blood loss and topography of the defect from 3D modeling were examined in 14 further cases. Inferior defects were associated with increased blood loss compared with anterior defects. Increased distance from cervix was associated with reduced blood loss (R2  = 0.352, P = 0.01). CONCLUSION: Three-dimensional models of PAS provide an accurate preoperative description of placental invasion and should be investigated as a tool for selecting patients for uterine-conserving surgery. Accurate 3D models of placenta accreta spectrum are achievable and may provide additional information, such as distance of the defect from the internal os.

Pneumomediastinum in a child with severe COVID-19.

The current global pandemic of the novel coronavirus SARS-CoV2 is a threat to the health and lives of millions of people worldwide. The latest statistics from the World Health Organisation show that there have been 6,515,796 confirmed cases worldwide with 387,298 confirmed deaths (last update 5 June 2020, 10:41 CEST). The majority of critically unwell patients with SARS-CoV2 are adults and the radiological findings associated with them are consistent throughout the literature. However, the reported paediatric cases are few, and as such, there is a limited body of evidence available. More international data is needed, not only on the clinical presentation, but also the radiological findings, so that health-care providers are better able to understand and diagnose this pandemic disease. We describe a case of a previously healthy 9-year-old female who presented to the Emergency Department with symptoms suggestive of raised intracranial pressure. Her CT revealed a medulloblastoma and post-operatively she tested positive for SARS-CoV2. She had a rapid deterioration in her clinical condition and required admission to the intensive care unit (ICU). We provide the supporting radiology along her clinical course in order to demonstrate important insights into this disease in children, including the unusual pnemomediastinum complications which occurred as part of her clinical course. This case is the first reported of its kind.

Maternal morbidity in placenta accreta spectrum following introduction of a multi-disciplinary service compared to standard care: an Irish perspective.

AIM: The purpose of this study is to compare maternal outcomes in patients with placenta accreta spectrum (PAS) when managed as part of a multi-disciplinary team (MDT) compared to standard care. METHODS: Patients in the standard care group were retrospectively identified from pathology records, with patients in the MDT group prospectively collected on an electronic database. Data on maternal demographics, delivery, estimated blood loss (EBL), transfusion requirements, and morbidity were recorded. RESULTS: Sixty patients were diagnosed with PAS between 2006 and 2019, of whom 32 were part of the standard care group and 28 in the MDT group. Compared to standard care, MDT care was associated with an increase in antenatal diagnosis from 56.3 to 92.9% (p < 0.0001), a significant reduction in EBL (4150 mL (800-19500) vs 1975 (495-8500), p < 0.0001), and transfusion requirements (median 7 (0-30) units of RCC vs 1 (0-13), p < 0.0001). CONCLUSION: PAS is associated with significant maternal morbidity and warrants management in an MDT setting with specialist input, which is associated with improved outcomes.
