Abstract
Sturge-Weber syndrome (SWS) type III, a rare neurocutaneous disorder, presents diagnostic challenges due to its variable clinical manifestations. The present study focuses on enhancing the understanding of this syndrome by conducting a detailed analysis of two pediatric cases and providing a comprehensive review of the existing literature. The cases, managed at the Children's Hospital Affiliated to Shandong University (Jinan, China), highlight the diverse clinical presentations and successful management strategies for SWS type III. In the first case, a 4-year-old male patient exhibited paroxysmal hemiplegia, epileptic seizures and cerebral angiographic findings indicative of left pia mater and venous malformation. The second case involved a 2.5-year-old male patient presenting with recurrent seizures and angiographic findings on the right side. Both cases underscore the importance of considering epileptic seizures, acquired and transient hemiplegia and cognitive impairments in the diagnosis of SWS type III. The present study provides insights into the effective use of both pharmacological and surgical interventions, drawing from the positive outcomes observed in these cases. The findings emphasize the need for heightened awareness and a meticulous approach in diagnosing and treating SWS type III, contributing to the better management and prognosis of this condition.

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
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.

Abstract
Background Sturge-Weber syndrome (SWS) is primarily diagnosed in pediatric population, but clinical presentation in late adulthood is rarely reported. Evolution of radiological findings in the adulthood variant of SWS with isolated leptomeningeal angiomatosis has never been reported to our knowledge. Case presentation We report here a case of an isolated temporo-parieto-occipital leptomeningeal angiomatosis on the right cerebral hemisphere in a sixty-two-year-old male who presented with generalized seizure, GCS score 14/15 (E4 V4 M6) with equal and reacting pupils, psychomotor slowing, left hemineglect and grade 4 power in the left upper and lower limbs. Over a period of 48 h his neurological status deteriorated, but recovered spontaneously over a week on titration with anticonvulsants. He had a prior history of treatment for focal leptomeningitis, three years ago. Cerebrospinal fluid (CSF) analysis showed glucose of 75 mg/dL, proteins of 65 mg/dL and culture grew no organisms. On follow-up, he had intermittent episodes of focal seizure for two years. Initial, computed tomography of brain showed hyperdense lesion in the parieto-occipital convexity subarachnoid space on the right cerebral hemisphere mimicking subarachnoid hemorrhage and computed tomography angiography showed no significant abnormality. Magnetic resonance imaging (MRI) of brain showed intense pial enhancement in the right temporo-parieto-occipital region with a subtle T2W hyperintense signal in the underlying subcortical white matter without edema or infarct or mass effect. Digital subtraction cerebral angiography (DSA) showed hypertrophy of the cerebral arteries, arteriolo-capillary bed and venules in the right temporo-parieto-occipital territory associated with early arterio-capillary and venous opacification. Serial MRI done after six months, one and two years showed increase in the T2W hyperintense signal in the subcortical white matter and cortical atrophy with no changes in the pial enhancement. MR perfusion imaging showed reduced cerebral blood flow (CBF) and cerebral blood volume (CBV) in the right parieto-temporo-occipital cortical and subcortical regions and increased perfusion in the leptomeninges with reduction of the NAA / Cr ratios in spectroscopy. Conclusion Conglomeration of various radiological findings in MRI, Perfusion, MRS and DSA with the clinical presentation can aid in establishing the diagnosis of this rare presentation of SWS-type 3 variant in late adulthood.

Abstract
INTRODUCTION Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome with typical clinical features including seizures, chronic hemiplegia, hemianopsia and intellectual impairment. Progressive clinical decline may be attributable, at least in part, to progressive venous ischemia. Transcranial Doppler (TCD) ultrasonography could be useful to monitor the degree of hemodynamic involvement and its progression. PURPOSE To determine whether there is an association between the degree of asymmetry in TCD and intensity of clinical and radiological involvement and whether there is a correlation between clinical changes and changes in serial TCD. METHODS In fourteen SWS pediatric patients and two "possible cases" (infants younger than two years old without previously known brain involvement, but with other typical signs of SWS) mean flow velocity in the middle cerebral arteries (MCA) was measured by TCD in both hemispheres. The percent difference between hemispheres (asymmetry) was calculated. Clinical and radiological severity was scored using scales. The correlation between TCD asymmetry and SWS clinical and radiological scores was analyzed at baseline, as well as the correlation between the changes in the different variables (TCD asymmetry, clinical and radiological cores) during evolution and in relation to the changes due to therapy. RESULTS The percentage of MCA velocity asymmetry was positively correlated with the clinical severity score (p = 0.04), and with seizure frequency (p = 0.014). Throughout evolution, therapeutic and clinical changes were associated with noticeable changes in transcranial doppler asymmetry in some cases. CONCLUSIONS TCD may provide a noninvasive method to assess the severity of blood flow abnormalities at baseline and a method to monitor children for progressive changes over time.

Abstract
The authors report a case of a diffuse choroidal hemangioma in the left eye of a 17-year-old girl. No evidence of leptomeningeal angiomatosis was found on magnetic resonance imaging and neither the medical history nor the clinical examination revealed a port wine birthmark on the left side of the face. Fine telangiectatic vessels were found on the bulbar conjunctiva of the ipsilateral eye. Because of the shared destination of the vessel-trigeminal-ectoderm complex that migrates toward the optic placode, forming choriocapillaris, upper facial skin (upper eyelid), and conjunctival vessels, an embryological basis can be offered for ophthalmic angiomatosis of Sturge-Weber syndrome. The authors propose that vascular angiomatosis of upper eyelid skin and conjunctiva are phenotypically equivalent and may be present or absent, independent of each other. Their proposed expansion of Sturge-Weber syndrome diagnostic criteria needs to be validated by a comprehensive review of ophthalmic features of Sturge-Weber syndrome.

Abstract
BACKGROUND The reproducibility of transcranial Doppler (TCD) ultrasound measurements in Sturge-Weber syndrome (SWS) and TCD's ability to predict neurological progression is unknown. METHODS In 14 individuals with SWS, TCD measured mean flow velocity, pulsatility index, peak systolic velocity, and end-diastolic velocity in the middle, posterior, and anterior cerebral arteries of the affected and unaffected hemisphere. TCD was performed either once (n = 5) or twice in one day (n = 9). We assessed the reproducibility of the measurements performed twice on the same day on subjects and compared the TCD measurements to previously published age-matched controls. Clinically obtained neuroimaging was scored for extent and severity of SWS brain involvement. Patients were prospectively assigned SWS neuroscores. RESULTS Middle cerebral artery velocity (r = 0.79, P = 0.04, n = 7), posterior cerebral artery velocity (r = 0.90, P = 0.04, n = 5), and anterior cerebral artery pulsatility index (r = 0.82, P = 0.02, n = 7) were reproducible TCD measurements comparing same-day percent side-to-side differences. In subjects with SWS, affected and unaffected mean peak systolic velocity and end-diastolic velocity in the middle, posterior, and anterior cerebral arteries were globally lower compared with age-matched control subjects. Subjects with the lowest affected middle cerebral artery velocity had the greatest worsening in the total neurological score between time 1 and 2 (r = -0.73, P = 0.04, n = 8) and the most severe magnetic resonance imaging involvement of the affected frontal lobe (r = -0.82, P = 0.007, n = 9). CONCLUSIONS TCD may be a reliable measure with potential clinical value, indicating that blood flow may be globally decreased in SWS patients with unilateral brain involvement.

Abstract
The novel concept explored in this case series is the primacy of headaches in generating seizures in those patients who suffer from migraine-triggered epilepsy. In this series, once the migraine headaches were fully suppressed, via daily scheduled opioid therapy, the seizures also stopped. Seizures returned, however, after the patients stopped the opiate regimen for any reason. The above pharmacological scenario is reminiscent of a similar but naturalistic course of events reported on the salutary effects of ketogenic diet, or changes in life style, in similar cases of migraine-triggered epilepsy. The primacy of migraine in treating what has been named 'seizure headaches' is seen in two other scenarios (i.e. the salutary effect of ketogenic diet and lifestyle changes resulting in restoration of one's sleeping pattern) thus stopping the migraine as well as the seizures associated with the same. This case series recounts the same phenomenon via utilizing around-the-clock maintenance opioid therapy.

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
Purpose:To review the clinical and neuroimaging features of a large series of patients with Sturge-Weber syndrome (SWS) seen over a 40-year period.Methods:Fifty-five patients with SWS (30 males and 25 females), were studied between 1965 and 2004. Results of neurological and ophthalmological examinations, electroencephalographic, and neuroimaging studies were reviewed. All patients were seen by one of the authors (I. P-C).Results:Epilepsy, hemiparesis, mental retardation and ocular problems were the most frequent and severe features of patients with Sturge-Weber syndrome in this series. The facial nevus flammeus was unilateral in 35 (63.5%) patients, bilateral in 17 (31%) and absent in 3 (5.5%) of the patients with leptomeningeal angiomas. Seven (41%) of the 17 patients with bilateral nevus flammeus had unilateral leptomeningeal angiomas. Seizures occurred in 47 patients (85.5%). Complete seizure control was obtained in 20 patients (42.5%), but in 2 of these 20 patients seizures were controlled only after lobectomy. All patients with unilateral or bilateral upper eyelid nevus flammeus had ipsilateral, unilateral or bilateral choroid-retinal angiomas. Only 20 (36%) of the 55 patients had low-normal or borderline intelligence (IQs<70). No relationship was observed between the size of the facial nevus flammeus and the severity of the brain lesion.Conclusions:Epilepsy, hemiparesis, mental retardation and ocular problems were the most frequent and severe features of patients with Sturge-Weber syndrome in this series. Cerebral lesions followed a progressive course during early childhood, but not later. Early surgical treatment controlled the seizures but other neurological problems such as hemiparesis and intellectual deficits showed a less satisfactory response. Early onset of seizures and poor response to medical treatment, bilateral cerebral involvement and unilateral severe lesions were indicative of a poor prognosis. Limited intelligence and social skills, poor aesthetic appearance and seizures complicated the integration of SWS patients. These features must be addressed in order for the patients improve social interactions, obtain gainful employment and achieve a better quality of life.

Abstract
Sturge-Weber syndrome (SWS) involves vascular malformations of the skin (facial port-wine stain), eye (glaucoma) and the brain (leptomeningeal angioma). Children born with a port-wine stain on the upper part of the face are also at risk for brain involvement. These infants and young children often develop seizures and other neurologic impairments. Progression in neurologic deficits does occur in some patients, but this is quite variable. A diagnosis of brain involvement is made with head computed tomography and contrast-enhanced MRI, but the sensitivity of standard imaging in young asymptomatic infants is low. Seizures occur in more than 75% of affected individuals. Clinical course and functional imaging suggest a role for both cerebral perfusion impairments and seizures in the development of neurologic deficits. Several controversies exist in the management of seizures and other neurologic impairments in SWS. Continued efforts are needed to develop a multicentered network for SWS clinical trials. Future research should be focused on this goal and on studies to improve our understanding of the cause(s) and molecular neuropathology of SWS.

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
We report a patient with Sturge-Weber syndrome without facial angioma, who presented with seizures and normal initial imaging results. The patient experienced several years without seizures before a sudden increase in seizure frequency, followed by an atypical evolution of imaging findings prompting biopsy to establish the diagnosis. This case highlights not only the rare presentation of isolated leptomeningeal angiomatosis, but also the potential for atypical evolution of imaging findings through the course of the disease. We detail the imaging findings of our case and review the potential pathophysiological basis for this appearance. Our experience suggests that repeat imaging is warranted in patients with suspected Sturge-Weber syndrome or those with intractable cryptogenic epilepsy, because some imaging features of Sturge-Weber syndrome may manifest over time.

Abstract
Sturge-Weber syndrome (SWS) is a neurocutaneous disorder comprised typically of a facial nevus, leptomeningeal angioma with calcifications, and seizures. SWS without a port-wine stain is a rare variant with only 30 cases reported in the literature. Here, a case of an 8-year-old girl with no cutaneous abnormalities presenting with medically intractable epilepsy and MRI and CT findings consistent with SWS is described. The patient underwent multistage surgery with subdural electrode monitoring before and after resection of the epileptogenic focus, with complete excision of the lesion and postoperative resolution of her seizures. This is the first reported case of three-stage surgery for localized resection of the seizure focus for SWS.

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
We present the unusual neuroimaging findings of focal cerebral leptomeningeal enhancement in association with corticopial calcifications, underlying a parietal convexity lipoma in 2 pediatric patients with normal psychomotor development, unremarkable physical findings, and recent onset of epilepsy. To our knowledge, this clinical and neuroradiological association has not been previously reported and shows overlapping features with Sturge-Weber syndrome without facial nevus and encephalocraniocutaneous lipomatosis, thus possibly representing an extremely rare variant within the spectrum of these congenital neurocutaneous disorders.

Abstract
Sturge-Weber syndrome (SWS) is defined by the association of a facial capillary malformation (port-wine stain), with a vascular malformation of the eye, and/or vascular malformation of the brain (leptomeningeal angioma). Variants exist where only one of these three structures is involved with the vascular malformation. SWS occurs sporadically and is congenital. Port-wine stains occur in 3 per 1000 live births. No good population-based data exist for how many people have Sturge-Weber syndrome, however, estimates range between one in 20-50,000 live births. This review summarizes literature regarding the main features and pathophysiology of Sturge-Weber syndrome, however the cause of this syndrome remains obscure. Recent advances in neuroimaging have provided important insights into the progression of neurologic injury that occurs as a result of impaired blood flow. Important limitations exist, however, as currently the early diagnosis and exclusion of Sturge-Weber syndrome is impaired by the poor sensitivity of imaging in the newborn period and early infancy. Several important controversies complicate our ability to care for these patients and include the questions of ideal timing of surgery, whether seizures themselves contribute to the neurologic injury, and what the role of low-dose aspirin should be. This review will summarize several recent advances in our understanding of the mechanisms of brain injury in SWS, new measures for quantifying the neurologic involvement and new approaches and controversies in the management of the neurologic complications.

Abstract
The natural history of Sturge-Weber Syndrome is variable where some patients have refractory epilepsy and persistent neurologic deficits while others do well. Also, evolution of MRI abnormalities is largely unknown. This long-term follow-up study tries to address these two issues. This retrospective and later prospective study followed 9 children with confirmed SWS. Clinical details of seizures, stroke-like episodes, neurologic and developmental deficits were ascertained specifically. Patients were divided into those with onset below or after 6 months of age for analysis. Disease was classified as active or inactive and correlations were made with the use of aspirin. All past, as well as prospectively acquired imaging was reviewed by two independent blinded neuroradiologists and the images were analysed as ictal (temporally related to seizure/stroke-like event) or interictal. Degree and extent of leptomeningeal enhancement was specifically looked for. Four boys and five girls were followed up for a mean of 6.1 years. Disease activity subsided in 8/9. Early-onset patients had a severe early course with significant residual deficits while late-onset patients did uniformly well. In 6 patients where aspirin was used, a stable course ensued. There was a significant increase in degree/extent of leptomeningeal enhancement during an ictus which returned to the baseline in the interictal state in all 7 patients where both images were available. Focal cerebral atrophy worsened in early-onset cases. In conclusion, SWS patients with onset of seizures/stroke-like events before 6 months of age seem to do worse with a severe early course and persistent neurologic deficits. However the course stabilizes after 5 years of age in most. Late-onset SWS patients have a benign course. Aspirin use is associated with a stable course though further studies are needed. The leptomeningeal enhancement appears to increase during acute events before returning to baseline suggesting that extent of the disease is probably best judged during the interictal state.

Abstract
OBJECT The authors sought to analyze the success rate of surgery in the management of medically intractable epilepsy in children with Sturge-Weber syndrome and to determine whether the extent and timing of surgery affected seizure and developmental outcomes. METHODS The authors performed a retrospective review of 27 children who underwent surgery at their institution for medically resistant epilepsy, and they examined the outcomes with regard to epilepsy control and neuropsychological development. Seventeen children (63%) experienced onset of their epilepsy when they were younger than 1 year of age. These patients were significantly more likely to have hemiparesis (p < or =0.001) and status epilepticus (p < or = 0.001) and be developmentally delayed (p < or = 0.025) than children whose epilepsy started later in life. Eight patients underwent a hemispherectomy (either anatomical or functional), and complete resolution of epilepsy was noted in all. Of the 19 patients in whom a focal resection was performed, 11 (58%) became seizure free. The 10 children in whom there was residual disease were more likely to have continuing epilepsy than the nine whose lesions were completely excised (p< or = 0.05). Seventeen children exhibited improvement in their developmental status following surgery. This improvement was significantly affected by completeness of resection (p< or = 0.05) and age at surgery (p< or = 0.009). Seizure freedom per se was not affected by the timing of surgery. CONCLUSIONS Medically intractable epilepsy in children can be treated effectively by surgery. The degree of resection or disconnection of diseased tissue, but not patient age at the time of surgery, is an important factor in achieving epilepsy control. Early surgery is more likely to improve developmental outcome.

Abstract
PURPOSE OF REVIEW Recent neuroimaging, clinical and molecular neuropathologic studies have provided new insights into the neurologic aspects of Sturge-Weber syndrome and are summarized here. RECENT FINDINGS Molecular studies suggest that abnormal brain blood vessel vasoactive and extracellular matrix molecule expression, as well as aberrant brain vascular innervation, contribute to the vascular malformation and its consequences. New magnetic resonance sequences may be useful for the early diagnosis of Sturge-Weber syndrome and perfusion magnetic resonance imaging, single photon emission computed tomography imaging, and positron emission tomography imaging studies are suggesting that decreased brain blood flow combined with altered hemodynamics during prolonged seizures may contribute to the neurologic declines in Sturge-Weber syndrome. SUMMARY Recent advances in our understanding of the neurologic issues offer promise for preventing brain injury in Sturge-Weber syndrome. More research is needed to translate advances in molecular research and neuroimaging advances into new treatment strategies for the disease.

Abstract
PURPOSE To investigate physiological alterations in Sturge-Weber syndrome (SWS) using MR perfusion imaging (PWI) and proton spectroscopic imaging (MRSI), and their association with neurological status. MATERIALS AND METHODS Six consecutive patients with a clinically established diagnosis of SWS underwent MRI using a 1.5 Tesla scanner. The protocol consisted of conventional anatomic scans, dynamic PWI, and multislice MRSI. A pediatric neurologist evaluated the neurological scores, and the imaging results were correlated with neurological scores using nonparametric correlation analysis. RESULTS Two patients had classic neuroimaging findings of unilateral cerebral atrophy with corresponding leptomeningeal enhancement and hypoperfusion (prolonged mean transit time). Two patients had bilateral disease, and two had normal symmetric perfusion. Among clinical measures, the highest correlation was between hemiparesis index and hypoperfused tissue volume (Spearman's correlation coefficient, rho = 0.943, P < 0.05). There was also a trend of correlation, although not statistically significant (P = 0.06), between the hemiparesis score and the NAA/Cr ratio in the mid to posterior centrum semiovale, lateral gray matter (GM), and splenium. CONCLUSION In SWS, PWI indicates cerebral hypoperfusion predominantly due to impaired venous drainage, with only the most severely affected regions in some patients also showing arterial perfusion deficiency. The extent and severity of the perfusion abnormality and neuronal loss/dysfunction reflect the severity of neurological symptoms and disability, and the highest correlation is found with the degree of hemiparesis. These parameters may be useful as quantitative measures of disease burden; however, further studies in larger number of patients (and with a more homogeneous age range) are required to confirm the preliminary findings reported here.

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
Sturge-Weber syndrome presents with vascular malformations of the brain, skin, and eye. Fibronectin has potent effects on angiogenesis, vessel remodeling, and vessel innervation density. To determine fibronectin expression in the blood vessels of Sturge-Weber syndrome brain and skin tissue and to quantify the density and circumference of Sturge-Weber syndrome blood vessels by type compared with controls, we performed in situ hybridization for fibronectin messenger ribonucleic acid (RNA) expression on six Sturge-Weber syndrome cortical brain samples, six epilepsy brain samples, skin from two port-wine stain skin lesions, and two normal skin samples from two subjects with Sturge-Weber syndrome. Fibronectin messenger RNA was expressed in blood vessels and endothelial cells in the parenchyma of both Sturge-Weber syndrome and control brain tissues and in skin samples. Fibronectin expression was significantly reduced by 23% in the Sturge-Weber syndrome meningeal vessels compared with the epilepsy controls (P < .01). Fibronectin expression was significantly increased by 19% in the Sturge-Weber syndrome parenchymal vessels compared with the epilepsy controls (P < .05). No difference was found in the expression of fibronectin in port-wine stain skin blood vessels. The density of leptomeningeal blood vessels in the Sturge-Weber syndrome brain tissue samples was 45% greater than in the epilepsy samples (P < .05). Blood vessel circumference was significantly decreased in the Sturge-Weber syndrome meningeal vessels compared with the controls (27%; P < .05). When blood vessels from different brain regions were compared, fibronectin expression was decreased in Sturge-Weber syndrome meningeal vessels and was increased in the parenchymal vessels. Altered blood vessel fibronectin expression in Sturge-Weber syndrome could contribute to abnormal vascular structure and function in this disorder.

Abstract
We describe a 7-month-old female with leptomeningeal angiomatosis who developed infantile spasms. She did not manifest facial nevus or ocular choroidal angioma. Leptomeningeal angiomatosis is characterized by venous angiomas of leptomeninges and usually accompanied by facial nevus, a condition known as Sturge-Weber syndrome. In Sturge-Weber syndrome, leptomeningeal angiomas can cause infantile spasms but much less frequently than in other neurocutaneous syndromes, such as tuberous sclerosis. This patient is the first reported case of leptomeningeal angiomatosis without facial nevus who developed infantile spasms. Leptomeningeal angiomas should be taken into consideration as a cause of infantile spasms, even in the absence of facial nevus. We suggest that this case is clinically within the spectrum of Sturge-Weber syndrome, and that the embryologic origin of this case is similar to that of Sturge-Weber syndrome.

Abstract
Sturge-Weber syndrome is a sporadic neurocutaneous disease characterized by facial port-wine stain, ocular abnormalities (glaucoma and choroidal hemangioma) and leptomeningeal angioma. Although the precise pathogenesis is unknown, available data regarding genetics, embryogenesis, and pathologic features are briefly reviewed. Clinical features vary from mild incomplete forms to full-blown disease with facial stain, seizures, and glaucoma. Frequencies of associated complications are reviewed. To plan treatment and further follow-up, diagnosis of glaucoma and intracranial involvement, even if asymptomatic, is fundamental in children at risk. Early neuroimaging features are important to recognize. Management of patients with Sturge-Weber syndrome is focused on treating associated neurologic and ocular abnormalities.

Abstract
Sturge-Weber syndrome is a neurocutaneous disorder classically presenting with a facial port-wine stain, vascular eye abnormalities, and an ipsilateral occipital leptomeningeal angioma. Children with Sturge-Weber syndrome often develop progressive neurologic problems. Data on the pathophysiology of Sturge-Weber syndrome are briefly reviewed. The embryologic, genetic, and pathologic considerations are discussed, as are theories regarding the mechanisms of the degenerative brain changes. Sturge-Weber syndrome likely results from an early embryologic malformation of vascular development affecting the development of the nearby skin, eye, and brain structures. Studies suggest that complex molecular interactions contribute to the abnormal development and function of blood vessels in Sturge-Weber syndrome. Neurologic deterioration in Sturge-Weber syndrome is likely secondary to impaired blood flow to the brain and is worsened by the presence of seizures. Insights from related areas are discussed, and future research studies are suggested.
