International Consensus Statement on the Radiological Evaluation of Dysraphic Malformations of the Spine and Spinal Cord. AJNR Am J Neuroradiol 2024:ajnr.A8117.

Abstract
Dysraphic malformations of the spine and spinal cord (DMSSC) represent a spectrum of common congenital anomalies typically (though not exclusively) affecting the lower spinal segments. These may be responsible for varying degrees of neurologic, orthopedic, and urologic morbidity. With advances in neuroimaging, it is now possible to better diagnose and evaluate these disorders both prenatally and postnatally. Neuroimaging, performed at the right time and with technique optimization, is integral in guiding clinical management. However, the terminology used to describe these lesions has become increasingly confusing, and there is a lack of consensus regarding the essential radiologic features and their clinical weighting. This variability in radiologic practice risks unstructured decision making and increases the likelihood of suboptimal, less informed clinical management. In this manuscript, the first of a series of consensus statements, we outline a standardized international consensus statement for the radiologic evaluation of children with suspected DMSSC derived from a critical review of the literature, and the collective clinical experience of a multinational group of experts. We provide recommendations for plain radiography, sonography, CT, and MR imaging in the evaluation of DMSSC with an emphasis on technique of imaging and imaging protocols.

Abstract
Patients with midline cutaneous anomalies of the craniospinal axis can be indicative of underlying embryonic defects, such as neural tube defects. Lack of familiarity with these midline aberrant skin findings may lead to misdiagnosis and delayed treatment. In this review, midline cutaneous anomalies of the craniospinal axis including aplasia cutis congenita, cranial and spinal dysraphism, and other developmental anomalies are explored in detail with emphasis on cutaneous clues to the diagnosis and appropriate workup.

Abstract
Background Tethered cord syndrome (TCS) is a type of occult spinal dysraphism, which necessitates early detection as an essential component of patient management in reducing complications. This study aimed to compare the findings of spinal cord ultrasonography between TCS patients and healthy individuals. Methods The current study is a case-control study of patients who were admitted to the Akbar and Ghaem Hospitals (Mashhad, Iran) in 2019. The study population comprised 30 children with TCS aged under two years old, and the control group included 34 healthy peers of the same age. The maximum distance of the spinal cord from the posterior canal wall was measured in millimeters using ultrasonography. Demographic and sonographic findings of each participant were recorded in checklists, which were then entered into SPSS software. P values less than 0.05 were considered statistically significant. Results The study included 30 children with TCS and 34 healthy individuals with a mean age of 7.67±6.39 months. TCS patients had a significantly shorter maximum distance of the spinal cord from the posterior wall of the spinal canal than the control group (1.75±0.62 mm vs. 2.79±0.76, P<0.001). After performing corrective surgery, the TCS patients indicated significant improvement in this interval (1.57±0.54 mm to 2.95±0.49 mm, respectively, P=0.001). Conclusion In comparison to children without TCS, the spinal cord was substantially closer to the posterior canal wall in TCS patients. However, these outcomes were improved significantly in patients after surgery.

Abstract
Abstract
Background
Spinal dysraphism (SD) encompasses congenital spinal defects that result from inappropriate fusion of the different midline osseous, mesenchymal, and neural elements. The primary tools for diagnosis of SD are both spinal ultrasonography (USG) and magnetic resonance imaging (MRI). Spinal USG is growingly being used as an initial screening modality with sensitivities and accuracies equivalent to those of MRI. Anorectal malformations (ARM) have ultimate association with many other congenital abnormalities, of which spinal dysraphism is one of the most common. The main aim of study was to assess the diagnostic accuracy of spinal USG as a screening modality in comparison with MRI in infants with closed spinal dysraphism. We also endeavored to highlight the associated spinal dysraphism radiological findings in patients with either ARM or back cutaneous stigmata.
Results
Our prospective diagnostic comparative study included 33 patients, all of whom underwent both MRI and USG. Both MRI and USG showed appreciable agreement in the assessment of spinal dysraphism. In comparison with the gold standard MRI, spinal USG revealed comparable diagnostic metrics: specificity (98.6–100%), sensitivity (66.6–91.6%), PPV (90–100%) and NPV (94.1–98.7%) in diagnosis of different types of spinal dysraphism. The main clinical presentation of nineteen patients was anorectal malformation (ARM), 11 of whom (57.9%) had evidence of associated spinal dysraphism. The most common types of ARM were cloacal malformation, recto-urethral fistula, and rectal atresia with no fistula. On the other hand, sixteen patients were mainly presented with back cutaneous stigmata, 11 of whom (68.8%) had associated spinal dysraphism. The most common presenting cutaneous stigmata were low back swelling and atypical dimples.
Conclusion
The front-line screening modality for infants with closed SD should be spinal USG, however, its main limitation is the restrained time window in the first 6 months of life. Infants with ARM should be screened for spinal anomalies, especially those with high and complex types. Infants with high-risk back cutaneous stigmata should be similarly screened, as well.

Sacral Spina Bifida Occulta: A Frequency Analysis of Secular Change. ANTHROPOLOGICAL REVIEW 2022.

Abstract
Substantial relaxation of natural selection beginning around 1900 changed the mutation/selection balance of modern genetic material, producing an increase in variable anatomical structures. While multiple structures have been affected, the temporal increase in variations of the sacrum, specifically, ‘Sacral Spina Bifida Occulta,’ have been reliably demonstrated on a localised scale. Calculation of largescale frequency has been hindered by the localised nature of these publications, the morphological variability of this variation, and potential pathological associations, which have produced divergent classifications, and conflicting reported rates of occurrence. A systematic review of the reported literature was conducted to provide an objective analysis of Sacral Spina Bifida Occulta frequency from 2500 BCE to the present. This review was designed to compensate for observed inconsistencies in reporting and to ascertain, for the first time, the temporal trajectory of this secular trend. A systematic review of Sacral Spina Bifida Occulta literature was conducted through the strict use of clinical meta-analysis criteria. Publications were retrieved from four databases: PubMed, Embase, the Adelaide University Library database, and Google Scholar. Data were separated into three historical groups, (1 = <1900, 2 = 1900 to 1980 and 3 = >1980), and frequency outcomes compared, to determine temporal rates of occurrence.
A total of 39/409 publications were included in the final analysis, representing data for 16,167 sacra, spanning a period of 4,500 years. Statistically significant results were obtained, with total open S1 frequency increasing from 2.34%, (79 to 1900CE), to 4.80%, (1900 to 1980CE) and to 5.43% (>1980CE). These increases were significant at p<0.0001, with Chi-squared analysis. A clear secular increase in the global frequency of Sacral Spina Bifida Occulta has been demonstrated from 1900 to the present. This research provides a novel and adaptable framework for the future assessment of variation distribution, with important implications for the fields of biological anthropology and bioarchaeology.

Abstract
Ultrasonography (US) is the first-line imaging modality for screening neonates and young infants with suspected spinal abnormalities. Whether performed for a suspicious congenital skin lesion, such as a lumbosacral tract or lipomatous mass, or abnormal neurological findings, US can help define spinal anatomy, characterize congenital spine malformations, and direct further work-up and management. The purpose of this article is to review the diagnostic imaging approach to infant spine US, including technique and indications, normal anatomy and variants with a focus on embryological origins, and classification and diagnosis of congenital spine malformations.

Abstract
Objectives: Occult spinal dysraphism is a congenital failure of fusion of the posterior vertebral arches with intact skin overlying the defect. Lumbosacral cutaneous manifestations are associated with a variable risk of occult spinal dysraphism. Tethered cord syndrome is a type of occult spinal dysraphism that puts abnormal traction on the spinal cord. This study analyzed neonates and infants who were referred to our pediatric urology practice and had evidence of lumbosacral cutaneous manifestation on physical examination. Methods: We reviewed the presence of lumbosacral cutaneous manifestations in neonates and infants evaluated in our pediatric urology clinic at our Institution over a 6-year period (1 March, 2015–28 February, 2021) with no prior diagnosis of lumbosacral cutaneous manifestation. All patients underwent a spinal ultrasound. Results: The most common lumbosacral cutaneous manifestations were bifurcated/duplicated gluteal folds (33%), gluteal asymmetry (19%), and sacral dimples (14%). A total of 34 (24%) patients had an abnormal spinal ultrasound; 15 (44%) of these infants underwent a lumbar magnetic resonance imaging. A coccygeal pit was statistically marginally higher in abnormal versus normal spinal ultrasound (p = 0.07). Patients with only one lumbosacral cutaneous manifestation (N = 121) were significantly more likely to have a normal spinal ultrasound compared to those with two or more lumbosacral cutaneous manifestation (N = 17) (79% vs 53%, p = 0.03). Conclusion: Due to the varying risk of certain lumbosacral cutaneous manifestations with occult spinal dysraphism, all patients with a lumbosacral cutaneous manifestation should undergo spinal ultrasound. This study also highlights the importance of urodynamic studies when there are abnormal cutaneous findings. Routine physical examinations of the lumbar region for cutaneous manifestations of occult spinal dysraphism are vital to ensure prompt management of tethered cord syndrome and avoid potentially devastating consequences.

Abstract
Cutaneous stigmata of the midline spine are a common question in pediatrics. They are known to be related to a higher likelihood of underlying dysraphic spinal abnormalities. Clear understanding of different types of cutaneous stigmata and correlating dysraphic findings can aid in appropriate imaging workup and timely management of patient pathology. In this article, the authors review midline spinal cutaneous findings in the pediatric population with occult spinal dysraphism.

Abstract
Purpose The purpose of this study was to identify the optimal timing for screening spinal cord ultrasonography (US) to detect filum terminale lipoma in infants. Methods We retrospectively reviewed infants (<12 months old) who underwent repeated spinal cord US between April 2011 and January 2019. We excluded infants if they only had one US examination, or if they had lesions other than filum terminale lipoma. Infants with filum terminale lipoma on magnetic resonance imaging were included in the lipoma group and the others in the control group. A linear mixed model was used to assess differences in the growth pattern of filum terminale thickness by age and group. The cutoff thickness on US and its diagnostic performance were assessed according to age. Results Among 442 infants with 901 US examinations, 46 were included in the lipoma group and 58 in the control group. Sixty-seven infants had unmeasurable filum terminale thickness on initial US, including 55 neonates (82.1%) before 1 month of age. The lipoma group had significantly greater filum terminale thickness than the control group (P<0.001). Thickness increased with age in the lipoma group (P=0.027). The sensitivity of US was 87.5% and the area under the receiver operating characteristic curve was 0.949 (95% confidence interval, 0.849 to 0.991) with a cutoff value of 1.1 mm in 4- to 6-month-old infants. Conclusion Screening spinal cord US could effectively diagnose filum terminale lipoma in 4- to 6-month-old infants with a cutoff thickness of 1.1 mm. Spinal cord US can be used to screen young infants with intraspinal abnormalities.

Abstract
IMPORTANCE Occult spinal dysraphism (OSD) is the most common congenital spinal anomaly. Cutaneous anomalies such as skin dimples or deviated gluteal folds are well known as stigmata of OSD and are indicators for further evaluation; however, the association between cutaneous anomalies and OSD has not been systemically evaluated. OBJECTIVE To evaluate the incidence of OSD and the proportion of OSD cases managed with a neurosurgical intervention among neonates or infants with various cutaneous stigmata. DATA SOURCES PubMed and Embase databases were searched for studies published up to July 25, 2018, that evaluated the proportion of OSD cases in neonates or infants with cutaneous stigmata. Search terms included ultrasound, dysraphism, dimple, and infant or neonate. The search was limited to English-language publications. STUDY SELECTION Two reviewers selected the studies evaluating the incidence of OSD among neonates or infants with cutaneous stigmata. DATA EXTRACTION AND SYNTHESIS The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines for data extraction were followed. Pooled proportions of OSD cases and OSD cases that were managed with a neurosurgical intervention were obtained using the generalized linear mixed model and maximum likelihood method. MAIN OUTCOME AND MEASURES The pooled incidence of OSD and OSD cases managed with neurological surgery among patients with cutaneous stigmata was the primary outcome. This outcome was also evaluated in each subgroup, and heterogeneity was explored using subgroup analysis. RESULTS A total of 15 studies, involving 6558 neonate or infant patients with various cutaneous stigmata, were included. The pooled proportion of OSD cases among the patients with cutaneous stigmata was 2.8% (95% CI, 2.1%-3.8%; I2 = 51.6%), and the proportion managed with neurological surgery was 0.6% (95% CI, 0.3%-1.3%; I2 = 66.4%). Cases with combined stigmata showed a significantly higher association with OSD than those with a single stigma (10.5% [95% CI, 6.9%-15.8%] vs 2.3% [%, 95% CI, 1.5%-3.5%]; P < .001). The pooled proportion of OSD cases among patients with an atypical dimple was significantly higher than among those with simple dimple (8.8% [95% CI, 4.5%-16.6%] vs 0.6% [95% CI of 1.4%-2.1%]; P = .001). CONCLUSIONS AND RELEVANCE The proportion of OSD in healthy, asymptomatic patients with midline cutaneous stigmata was low, and the proportion of patients who underwent a neurosurgical intervention was even lower. However, a careful evaluation as well as potential spinal magnetic resonance imaging is recommended for neonates or infants with combined stigmata or an atypical dimple for possible high-risk lesions.

Urinary Tract Anomalies in Patients With Anorectal Malformations: The Role of Screening and Clinical Follow-Up. Urology 2020; 143:216-220. [PMID: 32525076 DOI: 10.1016/j.urology.2020.05.052] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 05/14/2020] [Accepted: 05/25/2020] [Indexed: 11/20/2022]
Abstract
OBJECTIVE To evaluate the efficacy of the screening protocol and the clinical follow-up to detect urological anomalies (UA) in patients with ARM (ARM-P) in our institution. Secondary aim was to define the prevalence of UA and their relationship with severity of ARM. METHODS ARM-P were selected from a prospectively maintained database from 2000 to 2016. Exclusion criteria were: incomplete or with less than 3 years of follow-up and absence of surgical correction of the anorectal anomalies. Data from urological screening and follow-up were collected. Patients were divided into complex malformations (Group 1) and less complex malformations (Group 2). RESULTS One hundred seventeen of 149 were included in the study period (62 group 1, 55 group 2). UA were detected in 36/117 at birth (30.7%) with a difference between groups (P = .0005). VUR was detected in 16 (6 with hydronephrosis, 10 with normal ultrasound at birth). A bladder ultrasound after potty training showed 18 lower urinary tract dysfunction (LUTD; 15 with UA detected at birth, 3 with normal ultrasound). 8 LUTD were found during clinical follow-up, confirmed by ultrasound. Spinal MRI detected spinal cord anomalies (SCA) in 52/117 (44.4%). Considering the subgroups with neurogenic bladder and SCA there was a difference between groups (13/33 vs 1/19). CONCLUSION This study suggests that ARM-P are at increased risk of UA, most of which were detected on neonatal ultrasound. While screening protocol can show 88% of UA, follow-up can detect 12.9 % of total abnormalities without difference between groups. This data has to be considered when planning follow-up for these patients.

Acute presentations of intradural lipomas: case reports and a review of the literature. BMC Neurol 2019; 19:189.

Abstract
BACKGROUND Lumbosacral lipomas (LLs) may remain asymptomatic or lead to progressive neurological deterioration. However, sudden neurological deterioration is a rare and severe event. Herein, we report rare occurrences of sudden clinical deterioration in two previously asymptomatic children harbouring intradural LLs without dermal sinus tracts or signs of occult dysraphism. A review of the pertinent literature is also included. CASE PRESENTATION One child exhibited acute deterioration because of an epidural abscess associated with a filar lipoma without a sinus tract (probably caused by haematogenous spreading from a respiratory tract multiple infection), and the other child exhibited acute deterioration because of a very large, holocord syringomyelia-like cyst associated with a small conus lipoma. Both patients were 4 years old. In case #2, a previously undetected, severe tethered cord (conus at the S3-S4 level) was also present. A complete recovery was attained after an urgent surgical operation in both cases (in addition to targeted antibiotic therapy in case #1). All cases of deterioration in the literature were caused by abscess formation in dermal sinus tracts. CONCLUSIONS Prophylactic surgery may be indicated even in asymptomatic children that have tethered cord and surgically favourable LLs (small dorsal and filar LLs), especially if the conditions are associated with progressive syringomyelia. Similarly, intradural dermal sinus tracts should be regarded as surgery-indicated, even if the conus is in its normal position and the patient is asymptomatic because there is a consistent risk of severe, infection-related complications. Finally, asymptomatic patients with filar LLs and a normally located conus can be candidates for surgery or an accurate clinical and radiological follow-up.

Abstract
BACKGROUND A pattern of major and minor congenital anomalies, facial dysmorphic features, and neurodevelopmental difficulties, including cognitive and social impairments has been reported in some children exposed to sodium valproate (VPA) during pregnancy. Recognition of the increased risks of in utero exposure to VPA for congenital malformations, and for the neurodevelopmental effects in particular, has taken many years but these are now acknowledged following the publication of the outcomes of several prospective studies and registries. As with other teratogens, exposure to VPA can have variable effects, ranging from a characteristic pattern of major malformations and significant intellectual disability to the other end of the continuum, characterised by facial dysmorphism which is often difficult to discern and a more moderate effect on neurodevelopment and general health. It has become clear that some individuals with FVSD have complex needs requiring multidisciplinary care but information regarding management is currently lacking in the medical literature. METHODS An expert group was convened by ERN-ITHACA, the European Reference Network for Congenital Malformations and Intellectual Disability comprised of professionals involved in the care of individuals with FVSD and with patient representation. Review of published and unpublished literature concerning management of FVSD was undertaken and the level of evidence from these sources graded. Management recommendations were made based on strength of evidence and consensus expert opinion, in the setting of an expert consensus meeting. These were then refined using an iterative process and wider consultation. RESULTS Whilst there was strong evidence regarding the increase in risk for major congenital malformations and neurodevelopmental difficulties there was a lack of high level evidence in other areas and in particular in terms of optimal clinical management.. The expert consensus approach facilitated the formulation of management recommendations, based on literature evidence and best practice. The outcome of the review and group discussions leads us to propose the term Fetal Valproate Spectrum Disorder (FVSD) as we feel this better encompasses the broad range of effects seen following VPA exposure in utero. CONCLUSION The expert consensus approach can be used to define the best available clinical guidance for the diagnosis and management of rare disorders such as FVSD. FVSD can have medical, developmental and neuropsychological impacts with life-long consequences and affected individuals benefit from the input of a number of different health professionals.

Abstract
Ultrasound represents the first-line survey for the assessment of spinal cord development abnormalities. In fact, within 6 months of life, the non-ossification of neuronal arcs provides an excellent acoustic window that allows a detailed depiction of the spinal canal, its content and of the surrounding soft tissues. Nevertheless, an accurate ultrasound examination requires a complete knowledge of the anatomy, the condition of normality, the frequent anatomical variants and the main pathologies involved. This review is intended to briefly summarize the US technique, the main clinical indication and the key notions that could help to properly perform this type of ultrasound examination.

Abstract
PURPOSE To investigate the prevalence of occult spinal dysraphism (OSD) and subsequent neurosurgery in pediatric patients with isolated or combined dorsal midline cutaneous stigmata with or without other congenital malformations. METHODS We carried out a retrospective review of patients who underwent sonography or magnetic resonance imaging (MRI) for OSD because of suspicion of dorsal midline cutaneous stigmata (presumed to be a marker for OSD) between January 2012 and June 2017. Information about patient characteristics, physical examination findings, spinal ultrasound and MRI results, neurosurgical notes, and accompanying congenital anomalies was collected. RESULTS Totally 250 patients (249 ultrasound and one MRI screening) were enrolled for analysis. Eleven patients underwent secondary MRI examinations. The prevalence of OSD confirmed by an MRI was 2.4% (6 patients including one MRI screening). Five patients (2%) had tethered cord and underwent prophylactic neurosurgery, 3 of whom had a sacrococcygeal dimple and a fibrofatty mass. Prevalence of tethered cord increased as markers associated with a sacrococcygeal dimple increased (0.5% of the isolated marker group, 8.1% of the 2-marker group, and 50% of the 3-marker group). Incidence of OSD with surgical detethering in 17 other congenital anomaly patients was 11.8%, which was higher than the 1.3% in 233 patients without other congenital anomalies. CONCLUSION Our results suggest that the presence of dorsal midline cutaneous stigmata, particularly fibrofatty masses, along with a sacrococcygeal dimple is associated with OSD or cord tethering requiring surgery. OSD should be suspected in patients with concurrent occurrence of other congenital anomalies.
