Zhang Y, Niu J, Wang J, Cai A, Wang Y, Wei G, Wang H. Neurological function and drug-refractory epilepsy in Sturge-Weber syndrome children: a retrospective analysis. Eur J Pediatr 2024; 183:1881-1890. [PMID: 38305888 DOI: 10.1007/s00431-024-05448-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 11/25/2023] [Accepted: 01/21/2024] [Indexed: 02/03/2024]
Abstract
Epilepsy in Sturge-Weber syndrome (SWS) is common, but drug-refractory epilepsy (DRE) in SWS has rarely been studied in children. We investigated the characteristics of epilepsy and risk factors for DRE in children with SWS. A retrospective study was conducted to analyze the clinical characteristics of children with SWS with epilepsy in our hospital from January 2013 to October 2022. Univariate and multivariate logistic analyses were performed to investigate the factors influencing DRE in children with SWS. A total of 35 SWS children with epilepsy were included (51% male; mean age of presentation 3.6 ± 0.5 years), 71% of children with SWS had their first seizure within the first year of life, and the most common type of seizure was focal seizure (77%). Eleven (31%) patients developed DRE. The median age of onset for the first seizure was 1.0 years and all these cases were of SWS type I. Multivariate logistic analysis revealed that stroke-like episodes and seizure clusters were risk factors for DRE in SWS children. A poor neurological function group was observed in twenty-five children with SWS. Status epilepticus was a risk factor that affected the neurological function of SWS children with epilepsy. Conclusion: The study explored the epileptic features of children with SWS. The results revealed that stroke-like episodes and seizure clusters are risk factors for DRE in children with SWS. The occurrence of status epilepticus impacts the neurological function of SWS children with epilepsy. Thus, long-term follow-up is necessary to monitor outcomes. What is Known: • Sturge-Weber syndrome (SWS) is a rare neurocutaneous disorder, over 75% of children with SWS experience seizures, and 30-57% develop drug-refractory epilepsy (DRE), which leads to a poor outcome. • Drug-refractory epilepsy in SWS has been rarely studied in children, and the risk factors associated with DRE are unclear. What is New: • Clinical features of SWS children with drug-refractory epilepsy. • In SWS, stroke-like episodes and seizure clusters are risk factors of DRE, the occurrence of status epilepticus impacts the neurological function.

Abstract
The lack of therapeutics that prevent the development of epilepsy, improve disease prognosis or overcome drug resistance represents an unmet clinical need in veterinary as well as in human medicine. Over the past decade, experimental studies and studies in human epilepsy patients have demonstrated that neuroinflammatory processes are involved in epilepsy development and play a key role in neuronal hyperexcitability that underlies seizure generation. Targeting neuroinflammatory signaling pathways may provide a basis for clinically relevant disease-modification strategies in general, and moreover, could open up new therapeutic avenues for human and veterinary patients with drug-resistant epilepsy. A sound understanding of the neuroinflammatory mechanisms underlying seizure pathogenesis in canine patients is therefore essential for mechanism-based discovery of selective epilepsy therapies that may enable the development of new disease-modifying treatments. In particular, subgroups of canine patients in urgent needs, e.g. dogs with drug-resistant epilepsy, might benefit from more intensive research in this area. Moreover, canine epilepsy shares remarkable similarities in etiology, disease manifestation, and disease progression with human epilepsy. Thus, canine epilepsy is discussed as a translational model for the human disease and epileptic dogs could provide a complementary species for the evaluation of antiepileptic and antiseizure drugs. This review reports key preclinical and clinical findings from experimental research and human medicine supporting the role of neuroinflammation in the pathogenesis of epilepsy. Moreover, the article provides an overview of the current state of knowledge regarding neuroinflammatory processes in canine epilepsy emphasizing the urgent need for further research in this specific field. It also highlights possible functional impact, translational potential and future perspectives of targeting specific inflammatory pathways as disease-modifying and multi-target treatment options for canine epilepsy.

Abstract
BACKGROUND We summarize the history of individuals with Sturge-Weber syndrome (SWS) to inform clinical trial design and identify variations in care. METHODS We performed retrospective chart review of individuals with SWS from centers in New York City. We characterized data quality using a novel scoring system. For 13 clinical concepts, we evaluated if data were present and if they were of high quality. RESULTS We included 26 individuals with SWS (58% female; median age at initial visit 7 years; absolute range 1 month to 56 years]). Twenty-two had nevus flammeus, 13 glaucoma, four homonymous hemianopia, and 15 hemiparesis. Nineteen of 21 had at least one confirmed seizure with a known first seizure date, all before 24 months. Most (18 of 26, 69%) epilepsy was controlled. A plurality (10 of 23, 43%) had either normal cognitive function or mild cognitive delays. Aspirin use varied by site (P = 0.02)-at four sites, use was 0% (zero of three), 0% (zero of four), 80% (four of five), and 64% (nine of 14). Data were present for more than 75% of cases for 11 of 13 clinical concepts (missing: age of diagnosis, age of glaucoma onset). There were gaps in level of detail for motor impairments, glaucoma severity, seizure history, cognition, and medication history. CONCLUSIONS Clinical charts have important gaps in the level of detail around core SWS clinical features, limiting value for some natural history studies. Any clinical trial in SWS designed to prevent epilepsy should begin in the first year of life. Variations in use of aspirin suggest de facto clinical equipoise and warrant a comparative effectiveness study.

Abstract
Sturge-Weber syndrome (SWS) is a rare, noninherited neurovascular disorder characterized by abnormal vasculature in the brain, skin, and eye. Patients with SWS characteristically have facial capillary malformation, also known as port-wine birthmark, a leptomeningeal vascular malformation seen on contrast-enhanced magnetic resonance imaging images, abnormal blood vessels in the eye, and glaucoma. Patients with SWS have impaired perfusion to the brain and are at high risk of venous stroke and stroke-like episodes, seizures, and both motor and cognitive difficulties. While the activating R183Q GNAQ somatic mutation is the most common somatic mutation underlying SWS, recent research also implicates that GNA11 and GNB2 somatic mutations are related to SWS. Recent retrospective studies suggest the use of low-dose aspirin and vitamin D in treatment for SWS and prospective drug trials have supported the usefulness of cannabidiol and Sirolimus. Presymptomatic treatment with low-dose aspirin and antiepileptic drugs shows promising results in delaying seizure onset in some patients. This review focuses on the latest progress in the field of research for Sturge-Weber syndrome and highlights directions for future research.

Abstract
BACKGROUND Sturge-Weber syndrome (SWS) is a neurocutaneous disorder caused by a somatic mutation in the GNAQ gene, leading to capillary venous malformations with neurological, ocular, and cutaneous abnormalities. Descriptions of adult and elderly patients with SWS are scarce compared to those of neonates or children. METHODS We reviewed clinical, neuro-radiological and electroencephalographical findings of adult patients diagnosed with SWS, treated in our tertiary center for rare epilepsies. RESULTS Ten adult patients were identified with a median age of 48 years at inclusion. All patients had seizures, with features of temporal lobe involvement for five patients. One patient presented typical drug-resistant mesial temporal seizures with ipsilateral hippocampal sclerosis and leptomeningeal enhancement, and was treated surgically. Other patients presented typical neurological and brain imaging features found in SWS. One patient without visible leptomeningeal angioma or brain calcifications presented neurological symptoms (tonic-clonic generalized seizures) for the first time at the age of 56. Two of the oldest patients in our cohort with supratentorial leptomeningeal angioma displayed contralateral cerebellar atrophy, consistent with crossed cerebellar diaschisis. Over 70 years of follow-up data were available for one patient whose epilepsy started at the age of 6 months, offering a vast overview of the course of SWS, in particular the onset of dementia and contralateral micro-bleeds in relation to the leptomeningeal angioma. CONCLUSION The long follow-up of our cohort allows for a description of the course of SWS and a characterization of uncommon neurological features in adult and elderly patients.

Abstract
BACKGROUND Sturge-Weber syndrome (SWS) is a sporadic, neurocutaneous syndrome involving the skin, brain, and eyes. Because of the variability of the clinical manifestations and the lack of prospective studies, consensus recommendations for management and treatment of SWS have not been published. OBJECTIVE This article consolidates the current literature with expert opinion to make recommendations to guide the neuroimaging evaluation and the management of the neurological and ophthalmologic features of SWS. METHODS Thirteen national peer-recognized experts in neurology, radiology, and ophthalmology with experience treating patients with SWS were assembled. Key topics and questions were formulated for each group and included (1) risk stratification, (2) indications for referral, and (3) optimum treatment strategies. An extensive PubMed search was performed of English language articles published in 2008 to 2018, as well as recent studies identified by the expert panel. The panel made clinical practice recommendations. CONCLUSIONS Children with a high-risk facial port-wine birthmark (PWB) should be referred to a pediatric neurologist and a pediatric ophthalmologist for baseline evaluation and periodic follow-up. In newborns and infants with a high-risk PWB and no history of seizures or neurological symptoms, routine screening for brain involvement is not recommended, but brain imaging can be performed in select cases. Routine follow-up neuroimaging is not recommended in children with SWS and stable neurocognitive symptoms. The treatment of ophthalmologic complications, such as glaucoma, differs based on the age and clinical presentation of the patient. These recommendations will help facilitate coordinated care for patients with SWS and may improve patient outcomes.

Abstract
PURPOSE Sturge-Weber syndrome (SWS) is a neurocutaneous facomatosis characterized by facial and leptomeningeal angioma, glaucoma, seizures, and neurological disability. Therefore, a challenging multidisciplinary interaction is required for its management. The goal of this paper is to review the main aspects of SWS and to present an illustrative pediatric series. METHODS The pertinent literature has been analyzed, focused mainly on etiopathogenesis, pathology, clinical features, diagnostic tools, management, and outcome of the disease. Moreover, a series of 11 children operated on for refractory epilepsy between 2005 and 2015 (minimum follow-up 5 years, mean follow-up 9.6 years) is reported. The series consists of six boys and five girls with 6.5-month and 16.2-month mean age at seizure onset and at surgery, respectively. Seizures affected all children, followed by hemiparesis and psychomotor delay (81%), glaucoma (54%), and other neurological deficits (45%). RESULTS All children underwent hemispherectomy (anatomical in three cases, functional in two cases, hemispherotomy in six cases); one patient needed a redo hemispherotomy. Mortality was nil; disseminated intravascular coagulation and interstitial pneumonia occurred in one patient each; three children had subdural fluid collection. Eight patients (72%) are in the ILAE Class 1 (completely seizure and aura free), two in Class 2 (only auras, no seizure), and one in Class 3 (1-3 seizure days per year). AEDs discontinuation was possible in 73% of cases. The most important news from the literature concerned the pathogenesis (role of the mutation of the GNAQ gene in the abnormal SWS vasculogenesis), the clinical findings (the features and pathogenesis of the stroke-like episodes are being understood), the diagnostic tools (quantitative MRI and EEG), and both the medical (migraine, seizures) and surgical management (epilepsy). The epileptic outcome of SWS patients is very good (80% are seizure-free), if compared with other hemispheric syndromes. The quality of life is affected by the neurological and cognitive deficits. CONCLUSIONS SWS still is an etiological and clinical challenge. However, the improvements over the time are consistent. In particular, the neurosurgical treatment of refractory epilepsy provides very good results as long as the indication to treatment is correct.

Abstract
Epilepsy, a common multifactorial neurological disease, affects about 69 million people worldwide constituting nearly 1% of the world population. Despite decades of extensive research on understanding its underlying mechanism and developing the pharmacological treatment, very little is known about the biological alterations leading to epileptogenesis. Due to this gap, the currently available antiepileptic drug therapy is symptomatic in nature and is ineffective in 30% of the cases. Mounting evidences revealed the pathophysiological role of neuroinflammation in epilepsy which has shifted the focus of epilepsy researchers towards the development of neuroinflammation-targeted therapeutics for epilepsy management. Markedly increased expression of key inflammatory mediators in the brain and blood-brain barrier may affect neuronal function and excitability and thus may increase seizure susceptibility in preclinical and clinical settings. Cyclooxygenase-2 (COX-2), an enzyme synthesizing the proinflammatory mediators, prostaglandins, has widely been reported to be induced during seizures and is considered to be a potential neurotherapeutic target for epilepsy management. However, the efficacy of such therapy involving COX-2 inhibition depends on various factors viz., therapeutic dose, time of administration, treatment duration, and selectivity of COX-2 inhibitors. This article reviews the preclinical and clinical evidences supporting the role of COX-2 in seizure-associated neuroinflammation in epilepsy and the potential clinical use of COX-2 inhibitors as a future strategy for epilepsy treatment.

Abstract
Introduction:A robust neuroinflammatory response is a prevalent feature of multiple neurological disorders, including epilepsy and acute status epilepticus. One component of this neuroinflammatory reaction is the induction of cyclooxygenase-2 (COX-2), synthesis of several prostaglandins and endocannabinoid metabolites, and subsequent activation of prostaglandin and related receptors. Neuroinflammation mediated by COX-2 and its downstream effectors has received considerable attention as a potential target class to ameliorate the deleterious consequences of neurological injury. Areas covered: Here we describe the roles of COX-2 as a major inflammatory mediator. In addition, we discuss the receptors for prostanoids PGE2, prostaglandin D2, and PGF2α as potential therapeutic targets for inflammation-driven diseases. The consequences of prostanoid receptor activation after seizure activity are discussed with an emphasis on the utilization of small molecules to modulate prostanoid receptor activity. Expert opinion: Limited clinical trial experience is supportive but not definitive for a role of the COX signaling cascade in epileptogenesis. The cardiotoxicity associated with chronic coxib use, and the expectation that COX-2 inhibition will influence the levels of endocannabinoids, leukotrienes, and lipoxins as well as the prostaglandins and their endocannabinoid metabolite analogs, is shifting attention toward downstream synthases and receptors that mediate inflammation in the brain.

Abstract
PURPOSE Sturge-Weber syndrome (SWS) is a neurocutaneous disorder characterized by a facial port-wine stain, a glaucoma, and a leptomeningeal angioma. Epilepsy occurs in more than 75% of affected children, and seizures occurring in the first year of life are associated with a poor neurological prognosis. The aim of this study was to identify possible predictive markers of epilepsy on electroencephalogram (EEG) performed prior to seizure onset in children with SWS. METHODS This study included children with a diagnosis of SWS who had an EEG performed prior to seizure onset. Patients who did not develop epilepsy had a minimum follow-up of 3-years. We compared EEG characteristics of patients who developed epilepsy with patients who did not develop epilepsy by the time of their follow-up. RESULTS Eleven children were included in this study. EEG was performed at the median age of 2.1 months (range 1.0-22.1). Six children developed seizures with a time interval between EEG and seizure onset ranging from 2 days to 21 months. EEG background activity was asymmetric in 8 patients, 5 of whom later developed epilepsy. Focal interictal spikes or sharp waves were exclusively recorded in patients who developed later epilepsy (4 out of 6). One of these patients had a supposed false positive EEG as he did not developed epilepsy until 21 months later and one patient had a false negative EEG with seizures occurring 2 days after a normal EEG. CONCLUSION Spikes on EEG might be a useful marker to identify patients with SWS at risk of developing epilepsy. Their predictive value should be assessed in larger prospective studies.

Abstract
Infants with a high-risk distribution of port-wine stains are commonly screened for Sturge-Weber syndrome using brain magnetic resonance imaging. There is no consensus about which port-wine stain phenotypes to screen, optimal timing, screening sensitivity, or whether presymptomatic diagnosis improves neurodevelopmental outcomes. This state-of-the-art review examines the evidence in favor of screening for Sturge-Weber syndrome, based on its effect on neurodevelopmental outcomes, against the risks and limitations of screening magnetic resonance imaging and electroencephalography. A literature search of PubMed/MEDLINE was conducted between January 2005 and May 2017 using key search terms. Relevant articles published in English were reviewed; 34 articles meeting the search criteria were analyzed according to the following outcome measures: neurodevelopmental outcome benefit of screening, diagnostic yield, financial costs, procedural risks, and limitations of screening magnetic resonance imaging and electroencephalography. There is no evidence that a presymptomatic Sturge-Weber syndrome diagnosis with magnetic resonance imaging results in better neurodevelopmental outcomes. The utility of electroencephalographic screening is also unestablished. In Sturge-Weber syndrome, neurodevelopmental outcomes depend on prompt recognition of neurologic red flags and early seizure control. Small numbers and a lack of prospective randomized controlled trials limit these findings. For infants with port-wine stain involving skin derived from the frontonasal placode (forehead and hemifacial phenotypes), we recommend early referral to a pediatric neurologist for parental education, counselling, and monitoring for neurologic red flags and seizures and consideration of electroencephalography regardless of whether magnetic resonance imaging is performed or its findings.

Abstract
Sturge-Weber syndrome is the third most common neurocutaneous disorder, after neurofibromatosis and tuberous sclerosis, and impacts approximately 1 in 20000 live births. Sturge-Weber syndrome is not inherited, but rather occurs exclusively sporadically, in both males and females and in all races and ethnic backgrounds. Sturge-Weber syndrome presents at birth with a capillary malformation on the face (port-wine birthmark) with later diagnosis of abnormal vasculature in the eye and the brain which result in a range of complications. The underlying somatic mosaic mutation causing both Sturge-Weber syndrome and isolated port-wine birthmarks was recently discovered and is an activating mutation in GNAQ. When a newborn presents with a facial port-wine birthmark on the upper face, that child has a 15-50% risk of developing Sturge-Weber syndrome brain and/or eye involvement, depending on the extent of the birthmark, and close monitoring and appropriate screening is essential for early diagnosis and optimal treatment. Treatment options include laser therapy for lightening of the birthmark, eye drops and surgery for glaucoma management, and aggressive anticonvulsant treatment, low dose aspirin, and neurosurgery where necessary. Future possible treatments based upon new knowledge of the somatic mutation and downstream pathways are currently being considered and studied.

Abstract
BACKGROUND Sturge-Weber syndrome is often accompanied by seizures and neurocognitive deterioration, although previous studies have suggested that early functional brain reorganization may diminish the cognitive sequelae in some children with unilateral Sturge-Weber syndrome. The "rules" governing these plasticity mechanisms are poorly understood. In this study, we evaluated longitudinal changes of cognitive functioning (intelligence quotient [IQ]) and assessed the performance of clinical, electroencephalography (EEG), and magnetic resonance imaging (MRI) variables for predicting IQ in children with Sturge-Weber syndrome. METHODS Thirty-three young children (mean age: 3.3 years at baseline) with unilateral Sturge-Weber syndrome underwent MRI, scalp EEG, and neuropsychology evaluation twice, with a median follow-up of 2 years. None of the children had epilepsy surgery. Longitudinal IQ changes were calculated. Seizure variables, interictal EEG abnormalities, and extent and location of MRI brain involvement were correlated with IQ assessed at follow-up. RESULTS Global IQ showed a highly variable course with both increases and decreases over time. Lower IQ at baseline was associated with interval IQ increase. In univariate analyses, lower outcome IQ was associated with baseline EEG abnormalities (P < 0.001), young age at seizure onset (P = 0.001), high seizure frequency (P = 0.02), and early frontal-lobe involvement on MRI (P = 0.01). In multivariate analysis, EEG abnormalities at baseline remained a robust, independent predictor of outcome IQ. CONCLUSIONS The early trajectory of cognitive changes in children with unilateral Sturge-Weber syndrome is highly variable; children with improving IQ likely undergo effective unimpeded functional reorganization. Early onset, frequent seizures, and interictal epileptiform abnormalities on EEG likely interfere with this process resulting in poor cognitive functions. Future studies assessing interventions should target this high-risk subgroup to optimize cognitive outcome in Sturge-Weber syndrome.

Abstract
Sturge-Weber syndrome is a vascular malformation syndrome consisting of a facial port-wine birthmark associated with malformed leptomeningeal blood vessels and a choroid "angioma" of the eye. It is a rare neurocutaneous disorder that occurs sporadically, is not inherited, and is caused by a somatic mosaic mutation in GNAQ. In patients with Sturge-Weber syndrome, brain involvement typically presents in infancy with seizures, strokes, and stroke-like episodes, and a range of neurologic impairments. Standard treatment includes laser therapy for the birthmark, control of glaucoma through eyedrops or surgery, and the use of anticonvulsants. Increasingly low-dose aspirin is offered. Treatment with propranolol has been tried generally without the dramatic results seen in hemangiomas. Treatment with an anticonvulsant or low-dose aspirin or both before the onset of seizures is an option. Surgical resection may be offered to those whose seizures are medically refractory. Endocrine, medical rehabilitation and cognitive comorbidities are important to manage. In the future, new therapeutic options are likely to be offered stemming from preclinical studies and small pilot clinical trials currently ongoing. Discovery of the causative somatic mosaic mutation suggests new insights into the pathophysiology of this vascular malformation disorder, and potential novel treatment strategies for future study. The mutation results in constitutive overactivation of the Ras-Raf-MEK-ERK and the HIPPO-YAP pathways and inhibitors of these pathways may in the future prove useful in the treatment of Sturge-Weber syndrome.

Abstract
Epilepsy surgery has become an accepted treatment for drug resistant epilepsy in infants and children. It has gained ground in India over the last decade. Certain epilepsy surgically remediable syndromes have been delineated and should be offered surgery earlier rather than later, especially if cognitive/behavioral development is being compromised. Advances in imaging, particularly in MRI has helped identify surgical candidates. Pre-surgical evaluation includes clinical assessment, structural and functional imaging, inter-ictal EEG, simultaneous video -EEG, with analysis of seizure semiology and ictal EEG and other optional investigations like neuropsychology and other newer imaging techniques. If data are concordant resective surgery is offered, keeping in mind preservation of eloquent cortical areas subserving motor, language and visual functions. In case of discordant data or non-lesional MRI, invasive EEG maybe useful using a two-stage approach. With multi-focal / generalized disease, palliative surgery like corpus callosotomy and vagal nerve stimulation maybe useful. A good outcome is seen in about 2/3rd of patients undergoing resective surgery with a low morbidity and mortality. This review outlines important learning aspects of pediatric epilepsy surgery for the general pediatrician.

Abstract
OPINION STATEMENT We try to see the babies prior to the onset of symptoms so that their parents can receive anticipatory guidance regarding seizures and how to recognize and respond to them and so that proper referrals to ophthalmology can be made. If there is any concern on history, exam, or EEG then we obtain a magnetic resonance imaging (MRI) with contrast. If presymptomatic diagnosis of brain involvement is made then treatment with low-dose aspirin is offered and if the brain involvement is extensively bilateral then an anticonvulsant such as levetiracetam is offered as well. Seizures are treated aggressively with a goal of obtaining and maintaining complete seizure suppression as much as possible often with a combination of low-dose aspirin and two anticonvulsants such as levetiracetam and oxcarbazepine. For many patients, this will provide adequate control of their seizures and stroke-like episodes. If the patient fails medical management and seizures are regular and accompanied by plateaued development, significant hemiparesis and visual field deficit and the patient is unilaterally involved and a surgical candidate then surgical management is urged. When the seizures are less regular, little or no hemiparesis or visual field deficit exist, and development is reasonable then this decision is more difficult. For bilaterally involved patients surgery is usually not a good option unless seizures are very severe and mostly coming from one side. Other therapeutic options include the ketogenic/Atkins diet and vagal nerve stimulator although in our experience these usually do not result in cessation of seizures. Endocrine problems occur with increased frequency and must be treated when they are present. The recent discovery of the somatic mutation causing Sturge-Weber syndrome holds promise for new treatment options in the future.

Abstract
Sturge-Weber syndrome is a heterogeneous neurocutaneous syndrome with facial and leptomeningeal angiomas, glaucoma, seizures, stroke-like episodes, and mental retardation. The authors critically evaluated the clinical manifestations, outcome, and natural history in 30 patients with Sturge-Weber syndrome followed up from January 1985 to May 2010. Of the patients, 15 were males, age at diagnosis ranged from 1 month to 43 years. Typical port-wine stain nevus occurred in 26 (86%), it was bilateral in 2 (8%), and it was absent in 4 (4%). Nine patients had glaucoma (30%), 3 required surgery. Four had transient hemiparesis. All patients had seizures; they were well controlled in 22 (73.3%); in 8 they remained drug resistant. Three patients underwent surgery and became seizure-free. Of the 17 who had mental subnormality, 14 (82.4%) had seizure onset before 2 years. An early age at seizure onset and those with drug-resistant seizures had more severe degree of mental subnormality. Uncontrolled seizures, mental subnormality, visual handicap, and cosmetic disfiguration were the major impediments in life.

Abstract
Sturge-Weber syndrome (SWS) is a rare, sporadic neurocutaneous syndrome characterized by a classical triad of facial port wine nevus, ipsilateral leptomeningeal angiomatosis (LAM) and glaucoma. The incidence of SWS is 1/50,000 live births, although it is more often underreported. The incidence of SWS without facial nevus is not known, although very few patients without facial nevus have been reported. In these patients, the diagnosis of SWS is made by the findings of computed tomography, magnetic resonance imaging, and histopathology. Here, we report three patients with SWS from our cohort of 28 patients with SWS without facial nevus and discuss their clinical profile and outcome.

Abstract
Sturge-Weber syndrome is a neurocutaneous disorder associated with vascular abnormalities in the skin, eye, and brain leading to both acute and chronic cerebral hypoperfusion and, in some affected children, brain injury. Aspirin can reduce stroke-like events and seizure episodes and prevent further brain injuries in these patients. Although a few cases of intracranial hemorrhage in patients with Sturge-Weber syndrome have been reported, prior reports have not discussed this complication with regard to particular therapies. The authors present a toddler with Sturge-Weber syndrome who developed a subdural hematoma in the setting of a mechanical fall with minor head trauma. They discuss the possible role of aspirin in contributing to, or perhaps protecting against, intracranial hemorrhage in patients with Sturge-Weber syndrome. Further data are needed to establish the utility of aspirin in Sturge-Weber syndrome.

Abstract
Sturge-Weber syndrome is a neurocutaneous disorder with skin, eye, and brain involvement. Prior series suggest about 50% of patients have seizures/neurodeterioration. Low-dose (3-5 mg/kg/d) aspirin use in this population is controversial. This study further addresses the side effects and outcomes of low-dose aspirin usage in Sturge-Weber syndrome. Fifty-eight subjects on aspirin with brain involvement were analyzed in a retrospective chart review. Charts were evaluated for brain involvement, age at first seizure, and side effects. Subjects' clinical stability was compared using neurologic scores. The majority of subjects had neurologic scores reflecting reasonable seizure control (91%), none or mild hemiparesis (57%), no vision impairment (71%), and none or mild cognitive impairment (80%). Forty-nine reported no significant side effects, and 9 reported either allergic reaction or minimal to significant bleeding on aspirin. This cohort's clinical experience adds significant support for low-dose aspirin use to optimize neurodevelopmental outcome in Sturge-Weber syndrome with minimal side effects.

Abstract
Sturge Weber Syndrome is a rare neurocutaneous syndrome in which the severity is determined by degree of brain involvement and control of epilepsy. The authors describe and analyse clinical and imaging features of this syndrome, through a retrospective study of 13 patients (8 girls; aged between 15 days and 9 years at first visit). Twelve had facial angioma and one had atrichia corresponding to the area of brain involvement. Epilepsy was diagnosed in 6 cases, hemiplegia in 4, psychomotor delay in 7, and glaucoma in 4. Cerebral abnormalities were found in 10 children, 3 without neurological symptoms. The clinical signs and symptoms vary and there is not always a relationship between the severity of the clinical and neuroimaging abnormalities, which may occur even in the absence of neurological symptoms.

Abstract
AIM To review recent developments in the understanding, diagnosis, and treatment of Sturge-Weber syndrome (SWS). METHOD Members of the Brain Vascular Malformation Consortium Sturge-Weber Syndrome National Workgroup contributed their expertise to review the literature and present promising directions for research. RESULTS The increasing number of reports dealing with SWS over the last decade reflects progress in the diagnosis and understanding of the neurological involvement. The proliferation of centers and advocacy groups to care for patients with SWS and to stimulate research has aided the development of new insights into the clinical manifestations and the pathophysiology of neurological progression, and the development of novel hypotheses to direct future research. Many key questions remain, but the tools and networks to answer them are being developed. INTERPRETATION This review summarizes important new knowledge and presents new research directions that are likely to provide further insights, earlier diagnosis, improved treatments, and possibly, prevention of this syndrome.

Abstract
BACKGROUND Sturge-Weber syndrome (SWS) is a neurovascular disorder with a capillary malformation of the face (port-wine birthmark), a capillary-venous malformation in the eye, and a capillary-venous malformation in the brain (leptomeningeal angioma). Although SWS is a congenital disorder usually presenting in infancy, occasionally neurological symptoms first present in adulthood and most affected individuals do survive into adulthood with varying degrees of neurological impairment including epilepsy, hemiparesis, visual field deficits, and cognitive impairments ranging from mild learning disabilities to severe deficits. SWS is a multisystem disorder that requires the neurologist to be aware of the possible endocrine, psychiatric, ophthalmologic, and other medical issues that can arise and impact the neurological status of these patients. Some of these clinical features have only recently been described. REVIEW SUMMARY This review summarizes the neurological manifestations of SWS, discusses issues related to the diagnosis of brain involvement, relates major neuroimaging findings, briefly describes the current understanding of pathogenesis, and provides an overview of neurological treatment strategies. CONCLUSIONS Recent clinical research has highlighted several novel and lesser-known aspects of this clinical syndrome including endocrine disorders. Functional imaging studies and clinical experience suggests that neurological progression results primarily from impaired blood flow and that prolonged seizures may contribute to this process. Treatment is largely symptomatic although aggressive efforts to prevent seizures and strokes, in young children especially, may impact outcome.

Abstract
Sturge-Weber syndrome is a rare congenital disorder. Seizures, stroke-like episodes, glaucoma, headache, and developmental delay are frequently associated features. An Internet-based questionnaire was designed to assess the frequency of use, effectiveness, and safety of aspirin treatment in Sturge-Weber syndrome. Thirty-four of 98 subjects who completed the survey reported having used aspirin. The mean number of reported stroke-like episodes was reduced from 1.1 to 0.3 per month in the year after starting aspirin (n = 26, p = .014). The median number of seizures was significantly reduced from 3 to 1 episodes per month (n = 21, p = .002). Thirty-nine percent of subjects reported a history of complications (predominantly increased bruising or gum/nose bleeding) while on aspirin; however, none reported discontinuing aspirin because of side effects. Our study showed a significant relative reduction in both self-reported seizure frequency and stroke-like episodes after starting aspirin. It also suggests that low-dose aspirin can be safely used in these patients.

Abstract
Sturge-Weber Syndrome (SWS) is a rare neurocutaneous disorder involving facial capillary malformation (port-wine birthmark) and vascular malformation of the brain that is frequently associated with epilepsy, stroke-like episodes, cognitive deficits, motor impairment, and/or visual field cut. The four cases presented here (ages 8-9, two females) illustrate the broad range of physiologic involvement and associated neuropsychological functioning in SWS, and argue against the idea of a "typical" SWS neuropsychological presentation. Rather, we highlight a preliminary collection of disease status/severity factors thought to impact neuropsychological presentation in SWS, including degree of cortical involvement (unilateral versus bilateral; posterior only versus posterior/anterior), age at time of seizure onset, extent of seizure control, history of stroke-like episodes, and magnitude of neurologic decline/deficit. We discuss the need for broad-based assessment in this medical population, as various impairment combinations (e.g., perceptual, language, executive) create unique presentations as well as the need for individualized intervention.

Abstract
Several neurocutaneous syndromes have been reported in association with tuberous sclerosis complex. The coexistence of intracranial features of Sturge-Weber syndrome in patients with a confirmed diagnosis of tuberous sclerosis complex has been recently described. Several hypotheses can be raised to explain this association. The coexistence of signs of both diseases in the same patient could be explained by abnormal neural crest development, and by mutually enhanced common altered pathways. Mutation characterization of tuberous sclerosis complex and a better definition of the clinical and neuroimaging phenotypes could offer a crucial contribution to the etiopathogenetic mechanisms of these disorders.

Abstract
BACKGROUND AND PURPOSE Sturge-Weber syndrome (SWS) is frequently associated with neurologic complications such as seizures, so diagnosing this condition has important implications for patient management. The purpose of this study was to report unusual neuroimaging findings in patients with facial port-wine stain (PWS) and clinically suspected SWS. MATERIALS AND METHODS Cranial MR imaging was reviewed for all children with facial port-wine stain (PWS) involving the upper face and eyelids who were referred to Great Ormond Street Hospital between 2003 and 2007 for investigation of suspected SWS. Patients were excluded from further analysis if the imaging findings were normal on initial and subsequent scans and the subject remained free of neurologic disease, or if the imaging showed the well-recognized pattern of exclusively supratentorial pial enhancement representing the pial angioma of SWS. For the remaining patients, the neurologic, dermatologic, and ophthalmologic records were examined and all available imaging was reviewed by a neuroradiologist. We documented the presence and distribution of pial enhancement; corroborative features of SWS, such as atrophy, calcification, choroid plexus changes, and ocular abnormalities; and all other intracranial abnormalities. RESULTS Of the 62 patients referred for assessment, imaging findings were considered typical of SWS in 32 (52%) and were normal or showed abnormalities attributable to an unrelated pathology in 20 (32%). Of the remaining 10 patients, in 7 (11%), there was evidence of a pial angioma in an unusual distribution involving infratentorial structures, with the angioma in 1 patient being diagnosed at postmortem only; in 2 (3%), there were imaging abnormalities with some features in common with typical SWS, such as subcortical calcification, but with no evidence of pial enhancement; in 1 (1.6%), the initial MR imaging finding was normal, but repeat imaging subsequently revealed pial enhancement. CONCLUSIONS Involvement of infratentorial structures is common but may be relatively subtle and should be actively sought. Cases in which there are certain patterns of imaging abnormalities but an apparent absence of supratentorial pial enhancement on MR imaging may represent formes frustes of SWS; visualization of pial angiomatosis may also be delayed until later in childhood than expected.

Abstract
CASE REPORT A subgaleal hematoma (SGH) occurred in a young patient with Sturge-Weber syndrome (SWS) who was treated with aspirin after a mild head trauma. MATERIALS AND METHODS A 4-year-old child with SWS, who was chronically treated with aspirin at an antiplatelet dosage of 3 mg/kg per day, presented with extensive SGH and significant anemia after a mild head trauma. RESULTS AND CONCLUSION It is conceivable that the minor head trauma and chronic use of aspirin caused the SGH. Based on this event, the chronic use of aspirin in young patients with SWS, as suggested to prevent stroke-like episodes, is disputable.

Abstract
Phacomatoses, or neurocutaneous disorders, are a group of congenital and hereditary diseases characterized by developmental lesions of the neuroectoderm, leading to pathologies affecting the skin and the central nervous system. There is a wide range of pathologies affecting individuals at different moments of life. The genetics is variable: while neurofibromatosis 1 and 2, tuberous sclerosis and von Hippel-Lindau disease are all inherited as autosomal dominant traits, Sturge-Weber syndrome is sporadic. Other neurocutaneous disorders can be inherited as autosomal recessive traits (i.e., ataxia-telangiectasia), X-linked (i.e., incontinentia pigmenti) or explained by mosaicism (i.e., hypomelanosis of Ito, McCune-Albright syndrome). In this review, we discuss the major types of neurocutaneous disorders most frequently encountered by the neurosurgeon and followed beyond childhood. They include neurofibromatosis types 1 and 2, tuberous sclerosis, Sturge-Weber syndrome and von Hippel-Lindau disease. In each case, a review of the literature, including diagnosis, genetics and treatment will be presented. The lifespan of the disease with the implications for neurosurgeons will be emphasized. A review of cases, including both pediatric and adult patients, seen in neurosurgical practices in the Lille, France and Lausanne, Switzerland hospitals between 1961 and 2007 is presented to illustrate the pathologies seen in different age-groups. Because the genes mutated in most phacomatoses are involved in development and are activated following a timed schedule, the phenotype of these diseases evolves with age. The implication of the neurosurgeon varies depending on the patient's age and pathology. While neurosurgeons tend to see pediatric patients affected with neurofibromatosis type 1, tuberous sclerosis and Sturge-Weber syndrome, there will be a majority of adult patients with von Hippel-Lindau disease or neurofibromatosis type 2.
