Male R, Eriksson SH. The natural history of epilepsy and nonepileptic seizures in Sturge-Weber syndrome: A retrospective case-note review. Epilepsy Behav 2023; 145:109303. [PMID: 37348409 DOI: 10.1016/j.yebeh.2023.109303] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2023] [Revised: 06/02/2023] [Accepted: 06/02/2023] [Indexed: 06/24/2023]
Abstract
OBJECTIVE Patients with Sturge-Weber Syndrome (SWS) experience varying degrees of neurological problems - including epilepsy, hemiparesis, learning disability (LD), and stroke-like episodes. While the range of clinical problems experienced by children with SWS is well recognized, the spectrum of clinical presentation and its treatment during adulthood has been relatively neglected in the literature to date. This study explored the natural history of epileptic and nonepileptic seizures into adulthood in patients with SWS, and their treatment, and investigated whether any clinical factors predict which symptoms a patient will experience during adulthood. METHODS A retrospective case-note review of a cohort of 26 adults with SWS at the National Hospital for Neurology and Neurosurgery (NHNN). Childhood data were also recorded, where available, to enable review of change/development of symptoms over time. RESULTS The course of epilepsy showed some improvement in adulthood - seventeen adults continued to have seizures, while six patients gained seizure freedom, and no one had adult-onset seizures. However, seizures did worsen for some patients. Although no factors reached statistical significance regarding predicting continued epilepsy in adulthood, being male, more severe LD, having required epilepsy surgery, and bilateral cortical involvement may be important. Nonepileptic seizures (NES) also began during adulthood for four patients. SIGNIFICANCE By adulthood, there is some degree of improvement in epilepsy overall; while NES may occur for the first time. While the majority of the results did not survive adjustments for multiple comparisons, some interesting trends appeared, which require further investigation in a multicenter national audit. Patients with more neurologically severe presentations during childhood may continue to experience seizures. Careful monitoring and screening are needed during adulthood, to detect changes and newly developing symptoms such as NES, and target treatment promptly.

Abstract
INTRODUCTION Secondary analysis of hospital-hosted clinical data can save time and cost compared with prospective clinical trials for neuroimaging biomarker development. We present such a study for Sturge-Weber syndrome (SWS), a rare neurovascular disorder that affects 1 in 20 000-50 000 newborns. Children with SWS are at risk for developing neurocognitive deficit by school age. A critical period for early intervention is before 2 years of age, but early diagnostic and prognostic biomarkers are lacking. We aim to retrospectively mine clinical data for SWS at two national centres to develop presymptomatic biomarkers. METHODS AND ANALYSIS We will retrospectively collect clinical, MRI and neurocognitive outcome data for patients with SWS who underwent brain MRI before 2 years of age at two national SWS care centres. Expert review of clinical records and MRI quality control will be used to refine the cohort. The merged multisite data will be used to develop algorithms for abnormality detection, lesion-symptom mapping to identify neural substrate and machine learning to predict individual outcomes (presence or absence of seizures) by 2 years of age. Presymptomatic treatment in 0-2 years and before seizure onset may delay or prevent the onset of seizures by 2 years of age, and thereby improve neurocognitive outcomes. The proposed work, if successful, will be one of the largest and most comprehensive multisite databases for the presymptomatic phase of this rare disease. ETHICS AND DISSEMINATION This study involves human participants and was approved by Boston Children's Hospital Institutional Review Board: IRB-P00014482 and IRB-P00025916 Johns Hopkins School of Medicine Institutional Review Board: NA_00043846. Participants gave informed consent to participate in the study before taking part. The Institutional Review Boards at Kennedy Krieger Institute and Boston Children's Hospital approval have been obtained at each site to retrospectively study this data. Results will be disseminated by presentations, publication and sharing of algorithms generated.

Extent of Leptomeningeal Capillary Malformation is Associated With Severity of Epilepsy in Sturge-Weber Syndrome. Pediatr Neurol 2021; 117:64-71. [PMID: 33677229 DOI: 10.1016/j.pediatrneurol.2020.12.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 12/21/2020] [Accepted: 12/24/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND Individuals with Sturge-Weber syndrome (SWS) often expereince intractable epilepsy and cognitive decline. We hypothesized that the extent of the leptomeningeal capillary malformation (LCM) may correlate with the severity of neurological impairment due to SWS. We tested the hypothesis in a cross-sectional study of seizure severity and electroencephalographic (EEG) findings and a retrospective cohort study for surgical indications related to the extent of the LCM. METHODS We enrolled 112 patients and classified them according to LCM distribution: (1) bilateral, (2) hemispheric, (3) multilobar, and (4) single lobe. Age at seizure onset, seizure semiology and frequency, and EEG findings were compared. Surgical indications were evaluated for each group by Fisher exact test, and predictors for surgery were evaluated by univariate and multivariate analyses. Therapeutic efficacy was evaluated by the SWS-Neurological Score (SWS-NS). RESULTS The bilateral and hemispheric groups had early seizure onset (4.0 months old and 3.0 months old), frequent seizures (88.9% and 80.6% had more than one per month), focal-to-bilateral tonic-clonic seizures (88.9% and 74.2%), and status epilepticus (100% and 87.1%). The groups' EEG findings did not differ substantially. Surgical indications were present in 77.8% of the bilateral, 88.1% of the hemispheric, and 46.8% of the multilobar groups. Seizure more than once per month was a predictor of surgical treatment. Seizure subscore improved postoperatively in the hemispheric and multilobar groups. Even after surgical treatment, the bilateral and hemispheric groups exhibited higher SWS-NSs than members of the other groups. CONCLUSION Our study demonstrated a strong association between extensive LCM and epilepsy severity. Surgical intervention improved seizure outcome in patients with SWS with large LCMs.

Epilepsy Behav 2018; 80:202-207.

Abstract
PURPOSE Most children with Sturge-Weber syndrome (SWS) develop seizures that may contribute to neurocognitive status. In this study, we tested the hypothesis that very early seizure onset has a particularly detrimental effect on the cognitive and/or motor outcomes of children with unilateral SWS. We also tested whether side of SWS brain involvement modulates the effect of seizure variables on the pattern of cognitive abnormalities. METHODS Thirty-four children (22 girls; mean age 6.1years) with unilateral SWS and history of epilepsy in a longitudinal cohort underwent neurological and cognitive evaluations. Global intelligent quotient (GIQ), verbal intelligent quotient (VIQ), nonverbal intelligent quotient (IQ), and motor function were correlated with epilepsy variables, side and extent of brain involvement on magnetic resonance imaging (MRI). RESULTS Mean age at seizure onset was 1.3years (0.1-6years) and mean IQ at follow-up was 86 (45-118). Age at seizure onset showed a logarithmic association with IQ, with maximum impact of seizures starting before age 1year, both in uni- and multivariate regression analyses. In the left SWS group (N=20), age at seizure onset was a strong predictor of nonverbal IQ (p=0.001); while early seizure onset in the right-hemispheric group had a more global effect on cognitive functions (p=0.02). High seizure frequency and long epilepsy duration also contributed to poor outcome IQ independently in multivariate correlations. Children with motor involvement started to have seizures at/before 7months of age, while frontal lobe involvement was the strongest predictor of motor deficit in a multivariate analysis (p=0.017). CONCLUSION These findings suggest that seizure onset prior to age 1year has a profound effect on severity of cognitive and motor dysfunction in children with SWS; however, the effect of seizures on the type of cognitive deficit is influenced by laterality of brain involvement.

Abstract
Venous-related brain injury is a common form of cerebrovascular injury in children and encompasses a diverse group of cerebrovascular diagnoses. The purpose of this pictorial essay is to introduce the relevant anatomy, pathophysiology and various imaging patterns of venous-related cerebral injury in children. Unifying concepts to better understand the effects of venous hypertension in the developing brain will be emphasized. These unifying concepts will provide the imaging professional with a conceptual framework to better understand and confidently identify imaging patterns of venous-related cerebral injury.

Abstract
Visual functions in Sturge-Weber syndrome (SWS) may be impaired by glaucoma, diffuse choroidal haemangioma (DCH) or leptomeningeal angioma. The aim of this study was to gain better insight in the visual deficits of SWS patients. A systematic literature search using PubMed and Embase medical databases was performed to identify articles describing visual acuity (VA) and/or visual field (VF) findings in SWS patients. In addition, a Dutch multicentre cohort with 33 SWS patients was collected and the combined results of VA and VF findings are presented. Visual acuity results of 25 studies and VF results of 12 studies were suitable for data extraction. Description of the combination of both VA and VF findings was scarce. Homonymous hemianopia (HH) was present in 42% of SWS patients. Seventy per cent of eyes had a (near) normal vision, while VA of eyes with glaucoma or DCH was severely impaired in 28% and 67%, respectively. In the Dutch cohort, only 18% (6/33) of patients had (near) normal findings of both visual parameters. In addition, half of the patients with glaucoma suffered from a combination of a HH and VA impairment. In conclusion, although SWS patients are exposed to severe functional visual impairment due to the possible cumulative consequences of glaucoma, DCH and cerebral injury, description of the combination of both VA and VF results is scarce in the literature. Particularly, the combination of visual impairment due to glaucoma or DCH, and HH might be invalidating.

Abstract
Phakomatosis pigmentovascularis (PPV) is a rare cutaneous disorder characterized by combination of capillary malformation and other pigmented naevi. Four types and two subtypes have been described where subtype ‘a’ present only with cutaneous form and subtype ‘b’ also with systemic association like in Sturge-Weber syndrome or Klippel-Trenaunay syndrome. Hereby, we report a case where our patient presented with port-wine stain, Nevus of Ota, Sturge-Weber syndrome, and Klippel-Trenaunay syndrome; which has made it a rare combination.

Abstract
Background Sturge-Weber syndrome (SWS) is an uncommon etiology of hemiplegic migraine-like (HM-like) attacks, associated with epilepsy and mental retardation. Case We report the case of a 40-year-old woman with SWS who has been suffering from HM-like episodes since she was 24, with no history of seizure or mental retardation. Susceptibility weighted imaging (SWI)-MRI and CT scans have shown bilateral calcifications of the choroidal plexuses, a developmental venous anomaly with dilated transmedullary veins and a left parieto-occipital leptomeningeal angioma. 18F-Fluorodeoxyglucose (FDG)-PET/CT revealed a diffuse left-hemisphere hypometabolism. The comparison between the MRI performed at the age of 24 and the one performed at the age of 40 highlighted a progressive unilateral fronto-temporo-parietal atrophy. Surprisingly, even now, cognitive functions of this patient are relatively preserved. Lamotrigine permitted an improvement of HM-like attacks. Discussion Explanations for this minimally symptomatic form of SWS may be the absence of seizure, the importance of her deep venous drainage, the absence of cortical calcification and white matter impairment in the affected hemisphere, and, paradoxically, the severely asymmetric cortical metabolism. Furthermore, this case reinforces the hypothesis that alteration of cerebral hemodynamics could precipitate the cortical spreading depression giving rise to migraine with aura. Conclusion We propose to consider SWS as a cause of apparently isolated hemiplegic migraine and lamotrigine as a preventive medication in HM-like attacks.

Abstract
Sturge-Weber syndrome is a rare neurocutaneous disorder that often results in functional impairment caused by motor (typically hemiparesis) and cognitive deficits. A retrospective chart review of physiatric evaluation of 30 individuals, aged 4 mos to 55 yrs (median age, 2.4 yrs), with Sturge-Weber syndrome with brain involvement was conducted for the purpose of summarizing physiatric findings and recommendations in this cohort. Presence or absence of motor, cognitive, and behavioral concerns and need for orthoses, spasticity management, and therapy services were noted. Hemiparesis was common, but the need for intervention for spasticity was rare. Cognitive and behavioral concerns were noted frequently, meriting additional evaluation. Case vignettes are presented to highlight (1) a child with repeated functional setbacks in association with increased seizure frequency who, with seizure control, demonstrated return to functional baseline and subsequent further skill development and (2) a child with Sturge-Weber syndrome who made functional gains with constraint-induced movement therapy.

Abstract
BACKGROUND In Sturge-Weber syndrome (SWS), structural MRI abnormalities are most common in the posterior brain regions. Frontal lobe involvement increases the risk of motor impairment. The goal of this study was to determine whether Magnetic Resonance Spectroscopic Imaging (MRSI) can improve detection of frontal lobe involvement in children with SWS. METHODS Sixteen children (age: .9-10.4 years) with unilateral SWS underwent MRI with MRSI prospectively. N-acetyl-aspartate (NAA) and choline asymmetries in the posterior and frontal regions were measured. RESULTS Eight children presented normal-appearing frontal lobes on conventional MRI, but 7 of them showed abnormal NAA and/or choline content in the frontal lobe of the affected hemisphere. Lower frontal lobe gray matter NAA was associated with earlier onset of seizures (r= .76; P= .04) and impaired motor function (r=-.89, P < .001). Frontal NAA asymmetry was an independent predictor of motor function in a regression analysis (P= .01) CONCLUSION MRSI is more sensitive than conventional structural MRI for detection of frontal lobe involvement in SWS. Decreased frontal lobe NAA is an excellent predictor of motor functions. Thus, MRSI can provide complementary information for the assessment of normal-appearing brain regions, and may assist prognosis evaluation in children with SWS.

Abstract
BACKGROUND The natural course of Sturge-Weber syndrome (SWS) is poorly understood, although neurological symptoms are often progressive. AIMS To track longitudinal changes in brain glucose metabolism measured with positron emission tomography (PET) and their relation to clinical changes during the early course of SWS. METHODS Fourteen children (age 3 months to 3.9 years at enrollment) with SWS and unilateral leptomeningeal angioma underwent two consecutive glucose metabolism PET scans with a mean follow-up time of 1.2 years. Longitudinal changes of the extent of cortical glucose hypometabolism on the angioma side were measured and correlated with age, clinical seizure frequency and hemiparesis. RESULTS An increase in the size of the hypometabolic cortex was seen in 6 children, coinciding with an age-related increase in cortical glucose metabolism measured in unaffected contralateral cortex. These 6 patients were younger both at the initial (mean age 0.75 vs. 2.8 years; p<0.001) and the second scan (mean age 1.8 vs. 4.2 years; p=0.001) than those with no change in the extent of hypometabolic cortex (n=6). The area of cortical hypometabolism decreased in the two remaining children, and this was associated with resolution of an initial hemiparesis in one of them. Seizure frequency between the two scans was higher in children who showed progressive enlargement of cortical hypometabolism, as compared to those with no progression (p=0.008). CONCLUSIONS In SWS, detrimental metabolic changes occur before 3 years of age coinciding with a sharp increase of developmentally regulated cerebral metabolic demand. Progressive hypometabolism is associated with high seizure frequency in these children. However, metabolic abnormalities may remain limited or even partially recover later in some children with well-controlled seizures. Metabolic recovery accompanied by neurological improvement suggests a window for therapeutic intervention in children with unilateral SWS.

Abstract
AbstractA case of Sturge-Weber syndrome is described in which all paranasal sinuses were grossly enlarged. The mastoid, petrous and squamous portions of the temporal bone on both sides were fully pneumatized and the right orbit was distorted. There was resistant infection in the left maxillary sinus. These unusual features were well demonstrated by computed tomographic scans.

Abstract
Recent studies of regional cerebral blood flow (rCBF) and cerebral metabolism in patients with Sturge-Weber syndrome (SWS) have demonstrated a regional decrease of CBF and metabolism in the affected hemisphere, which may reflect the neurological status of the patients. Therefore, in the present study, we use stable xenon computed tomography (xenon-CT) and/or (99m)technetium hexamethylprophylene amine oxime ((99mTc)HMPAO) single photon emission computed tomography (SPECT) to determine whether the degree of cerebral hemodynamic disturbance correlates with the severity of motor impairment in 5 children with Sturge-Weber syndrome. We found that 5 patients had great variation in clinical progression and outcome, but MR imaging investigations all revealed extensive but stable abnormalities. rCBF, assessed by stable xenon-CT and/or (99mTc)HMPAO-SPECT, showed perfusion defect in all subjects. However, the xenon-CT disclosed reduction of rCBF and cerebrovascular reactivity in patients with severe motor paralysis. The total CBF and rCBF detected by xenon-CT were improved after clinical status was stabilized. We conclude that the motor function impairment in patients with SWS appeared to better correlate with the degree of rCBF impairment than with the abnormalities in conventional neuroimaging. Therefore, the quantitative CBF study is one of the diagnostic modality of choice in evaluating the neurological status in patients with SWS.

Abstract
Cutaneous and leptomeningeal vascular malformations are hallmarks of the Sturge-Weber Syndrome (SWS), resulting in chronic ischemic tissue damage. The mechanisms underlying the pathobiology of these progressive lesions are unknown. Aberrant expression of angiogenic factors has been implicated in the genesis and maintenance of vascular malformations. To assess the role of angiogenesis in SWS vascular lesions we determined the expression of key angiogenic factors by immunohistochemistry and in situ hybridization in 8 SWS patients (age: 8 months to 18 years). We observed increased expression of vascular endothelial growth factor (VEGF), its cognate receptors VEGFR-1, VEGFR-2, and neuropilin (NP)-1 as well as Tie2 in leptomeningeal SWS blood vessels. Intriguingly, these factors are known to be transcriptionally induced by hypoxia-inducible factor (HIF). The HIF system has emerged as the key regulatory system of responses to hypoxia. Immunohistochemical analysis demonstrated markedly elevated nuclear HIF-1alpha and HIF-2alpha protein levels in SWS vessels. Concomitantly, SWS vessels revealed signs of enhanced endothelial cell (EC) turnover as evidenced by increased EC proliferation and apoptosis. Thus, in terms of angiogenesis, vascular malformations in SWS are not static lesions but constitute dynamic structures. Our observation of a dysregulated HIF-alpha expression in SWS vessels are in agreement with recent findings that EC-specific HIF activation provides a setting which supports and sustains angiogenesis and could be of potential use for developing therapeutic strategies to treat these currently incurable lesions.

Abstract
Sturge-Weber syndrome is a neurocutaneous syndrome with a facial port-wine nevus and neurologic features, typically including seizures and hemiparesis. Glaucoma may also occur. MRI features include leptomeningeal angiomatosis, cortical and pial calcifications, and angiomatous change of the choroid plexus. We reviewed a subset of patients with Sturge-Weber syndrome with the rare finding of deep venous occlusion, and present such a case, unusual by comparison to previously reported cases of Sturge-Weber syndrome with deep venous occlusion. Six previously reported cases were reviewed. All cases presented with seizures; five of six had evidence of leptomeningeal angiomatosis; half had cerebral hemiatrophy. This report presents a unique case lacking clinical seizures, but with a port-wine stain and congenital glaucoma. This patient lacked the radiologic findings of leptomeningeal angiomatosis and hemicerebral atrophy, but demonstrated deep venous occlusion with frontal venous collaterals. There is a wide spectrum of findings in Sturge-Weber syndrome. The lack of seizures and angiomatosis in this case are likely "true-true" and related. The case illustrates the unusual finding of deep venous occlusion in Sturge-Weber syndrome occurring without leptomeningeal angiomatosis. Additionally, it demonstrates that although the initial evaluation is normal, patients may later manifest clinical characteristics of Sturge-Weber syndrome.

Abstract
Sturge-Weber syndrome is a neurocutaneous disorder with vascular malformations of the skin, brain, and eye. The objective of this study was to determine whether cortical atrophy in patients with Sturge-Weber syndrome correlates with clinical severity. Eighteen subjects (age 4 months-35 years) with unilateral Sturge-Weber syndrome received a neurologic examination and submitted previous magnetic resonance imaging (MRI) films. A blinded investigator assigned clinical severity scores based on seizures, hemiparesis, visual field cut, and cognitive impairments. Computer-aided analysis of MRIs produced laterality scores for cortical volume asymmetry. A significant relationship existed between clinical severity and laterality scores (Spearman's rho = -0.804; P < .001). Laterality scores also correlated well with hemiparesis subscores and weakly with cognitive impairment subscores (Kendall's tau b; P < .05). Using this simple, computer-aided analysis, cortical volume asymmetry correlated with clinical status. This method offers the advantages of relative simplicity, objectivity, and wide applicability to films from outside institutions, as would be encountered in clinical practice.

Abstract
The purpose of this study is to report different patterns of visual cortex activation in patients with Sturge-Weber syndrome as compared with healthy control subjects. Utilizing a visual paradigm of flashing lights, three children with Sturge-Weber syndrome were studied with functional magnetic resonance imaging. The results are compared with those documented in eight normal sedated children, and six young adult awake volunteers, using the same paradigms. All adult volunteers manifested bilateral activation in primary visual cortex (Brodmann's 17 and 18 areas). Two of them also had activation in secondary visual cortex (Brodmann's 19 area). In the eight sedated normal children, seven manifested activation in primary visual areas. The last exhibited no activation. The patients with Sturge-Weber syndrome demonstrated in the affected occipital lobe increased activation in one patient (11 months old), no activation in the second (12 years of age), and abnormal distribution of the activation in the third (11 months old). This report demonstrates that the vascular malformation of Sturge-Weber syndrome does not necessarily prevent cortical activation in the expected occipital cortex and may be associated with different patterns of abnormal activation. Assessing cortical function with functional magnetic resonance imaging in patients with Sturge-Weber syndrome may be helpful in decisions of surgical management and counseling.

Abstract
Sturge-Weber syndrome is a rare disorder that occurs with a frequency of approximately 1 per 50,000. The disease is characterized by an intracranial vascular anomaly, leptomeningeal angiomatosis, most often involving the occipital and posterior parietal lobes. Facial cutaneous vascular malformations, seizures, and glaucoma are among the most common symptoms and signs. Stasis results in ischemia underlying the leptomeningeal angiomatosis, leading to calcification and laminar cortical necrosis. The clinical course is highly variable and some children experience intractable seizures, mental retardation, and recurrent strokelike episodes. In this review, we describe the syndrome's characteristic features, clinical course, and optimal management.

Abstract
Abnormal cerebral venous drainage is associated with hypoxia and glucose deprivation, which can account for progressive neurologic deterioration in Sturge-Weber syndrome. Although developmental delay is common in Sturge-Weber syndrome, bihemispheric calcification is uncommon. Computed tomography (CT) and magnetic resonance imaging (MRI) were used to study the neuroanatomy, while single photon emission computed tomography (SPECT) was used concurrently to evaluate perfusion and glucose metabolism using 99mTc hexamethylpropyleneamine oxime (HMPAO) and [18F] fluorodeoxyglucose (FDG), respectively. Ten patients (10 to 22 years of age) with previously diagnosed Sturge-Weber syndrome, port-wine nevi, and clinical evidence of seizures or stroke-like episodes were studied. Five children with onset of seizures in the first year of life had overall clinical severity comparable to that of children with later-onset seizures. Calcification was present in both hemispheres in one patient; six additional patients had other radiologic evidence of bihemispheric disease; SPECT studies detected bihemispheric disease in four cases. Our study is the first to concurrently evaluate structure, perfusion, and glucose metabolism in Sturge-Weber syndrome and to show a mismatch between functional and structural brain imaging in both cerebral hemispheres. Widespread abnormalities of cerebral perfusion and glucose metabolism might explain the high prevalence of developmental delay associated with Sturge-Weber syndrome. Longitudinal studies are needed to define better the natural history of neurologic deterioration and radiologic progression that relates to central nervous system circulatory dysfunction in Sturge-Weber syndrome.

Abstract
OBJECTIVES Functional cerebral imaging PET and SPECT have shown hypometabolism and hypoperfusion in the area of vascular malformation in children with epilepsy due to Sturge-Weber syndrome. However, data are scarce in infants and do not exist in patients with Sturge-Weber disease without epilepsy. The pattern of perfusion during the first two years of life was studied including patients before the onset of seizures. METHODS Twenty two infants with later confirmed Sturge-Weber disease underwent SPECT examination using TOMOMATIC 564 (Medimatic) and xenon-133 at ages ranging from 8 days to 25 months. Twelve had never had seizures before SPECT and seven underwent a second SPECT a mean seven months later. Cerebral blood flow (CBF) was measured in the whole hemisphere and in the part of the cortex involved in the vascular malformation on both sides as well as a "pathological to normal" index for the hemisphere and vascular malformation. These values were compared with normal age paired values. RESULTS Compared with controls, CBF and the indices in the hemisphere and vascular malformation were significantly decreased in patients who already had had seizures before SPECT, whereas they were significantly increased in 75% of the patients who had never had any seizures. On second SPECT, the indices were decreased in all patients, including the four who still remained non-epileptic. CONCLUSIONS SPECT therefore detects CBF asymmetry in infants with Sturge-Weber disease, which tends to shift with age. The cortex involved in the vascular malformation is hyperperfused during the first year of life before first seizures. The classic hypoperfusion appears after one year of age, even in non-epileptic patients.
