INTRODUCTION: Photodynamic therapy (PDT) has shown substantial benefit in the treatment of choroidal hemangioma (CH) in recent years. This report describes the use of PDT with overlapping spots in a patient with Sturge-Weber syndrome (SWS) and large circumscribed CH. CASE PRESENTATION: A 9-year-old girl with SWS and a history of glaucoma in her left eye was referred to a retina clinic for possible macular changes. Examination revealed decreased vision in the left eye, pigmentary changes in the macula, and choroidal thickening in the posterior pole. After being lost to follow-up for 2 years, the patient returned with further vision deterioration with best-corrected visual acuity (BCVA) of 20/150 and new subretinal fluid (SRF). Imaging findings were consistent with a diagnosis of CH and SRF. PDT with verteporfin was initiated on the entire area with multiple overlapping spots, resulting in resolution of SRF and improvement in visual acuity and choroidal contour. At 18-month post-treatment, the patients BCVA was 20/25 with no recurrence of SRF or increased choroidal thickening. Significant pigmentary changes and subretinal hyper-reflective material were observed in the OCT of the treated area. CONCLUSION: Multiple overlapping laser spots of PDT can result in longstanding regression of large circumscribed CH in a patient with SWS with excellent final visual acuity. However, significant subretinal changes may also result following this method of treatment.

Key Clinical Message: This report presents a 14‐year‐old male with seizures and facial port‐wine stains, who upon further evaluation was found to have SWS. Early diagnosis and consistent treatment of Sturge–Weber syndrome in children are essential to prevent seizures and improve quality of life. Anti‐seizure medications play a crucial role in preventing and controlling seizures. [ABSTRACT FROM AUTHOR]

Purpose: The traditional imaging findings reported in Sturge–Weber syndrome (SWS) include endpoints of cortical injury—cortical atrophy and cortical calcifications—but also what has been termed a "leptomeningeal angiomatosis," the latter recognized and reported as a leptomeningeal enhancement on magnetic resonance imaging (MRI). The objective of this study is to demonstrate through neuropathological correlation that the "leptomeningeal angiomatosis" in patients with Sturge–Weber syndrome (SWS), represents a re-opened primitive venous network in the subarachnoid space that likely acts as an alternative venous drainage pathway, seen separately to abnormal pial enhancement. Materials and methods: Retrospective review of MR imaging and surgical pathology of patients that underwent surgery for epilepsy at a tertiary, children's hospital. A pediatric radiologist with more than 20 years of experience reviewed the MR imaging. Surgically resected brain specimens that had been sectioned and fixed in 10% paraformaldehyde for histologic processing, following processing and paraffin embedding, were cut into 5-µm unstained slides which were subsequently stained with hematoxylin and eosin (H&E). Slides were re-examined by a board-certified pediatric neuropathologist, and histologic features specifically relating to cerebral surface and vascularity were documented for correlation with MR imaging of the resected region performed prior to resection. Results: Five patients were reviewed (3 boys and 2 girls; the median age at the onset of seizures was 12 months (IQR, 7 to 45 months); the median age at surgery was 33 months (IQR, 23.5 to 56.5 months)). Surgical procedures included the following: 4, hemispherotomy (right: 2, left: 2) and 1, hemispherectomy (right). A subarachnoid space varicose network was present on both MRI and histology in 4 patients. Calcifications were seen on both MRI and histology in 3 patients. Abnormal leptomeningeal enhancement was present in 5 patients and seen separately from the subarachnoid vascular network in 4 patients. Conclusion: Histopathology confirmed the MRI findings of a subarachnoid space varicose network seen separately from leptomeningeal enhancement and presumed to represent an alternative venous drainage pathway to compensate for maldevelopment of cortical veins, the primary abnormality in SWS. No pial-based angioma was identified. [ABSTRACT FROM AUTHOR]

Sturge-Weber syndrome (SWS) is a rare congenital disorder marked by facial port-wine birthmarks, neurological impairments, and ocular anomalies. Our case report describes a 20-year-old man with SWS who presented with right-sided weakness, slurred speech, and oral dyskinesia. Laboratory studies demonstrated elevated prolactin levels, and imaging confirmed a pituitary macroadenoma. While not well-documented, the association between SWS and pituitary macroadenomas is emerging based on current evidence. The potential link may involve embryological, genetic, or hormonal factors influencing the simultaneous development of these conditions. This case highlights the need for a thorough evaluation in patients with SWS, incorporating both neuroimaging and endocrine assessments to manage associated complications effectively. Further research is necessary to investigate the link between SWS and pituitary tumors. Establishing evidence-based guidelines for the screening and management of these patients will improve outcomes and provide a standardized approach to care.

Sturge–Weber syndrome (SWS), also known as encephalo-trigeminal angiomatosis, is a sporadic, congenital neurocutaneous disorder. It is characterized by capillary malformation affecting the brain, meninges, eyes, and skin. The ophthalmic, maxillary, and mandibular distributions of the trigeminal nerve are involved. Eye involvement with vascular malformation produces glaucoma and can lead to vision loss. Here, we present a rare case of SWS with port-wine stain, painful vision loss in left eye, and open-angle glaucoma in the other eye of the same patient. The painful blind eye was treated with cyclocryotherapy with successful control of intraocular pressure.

Abstract Objective This study identified biomarkers of neurological outcome in Sturge‐Weber syndrome (SWS) via urine angiogenic factors and captured longitudinally derived natural history data within an SWS cohort. Methods This longitudinal, prospective, multicentered study of 61 people with SWS aged 0.4–55 years reports port‐wine birthmark score, Neuroscore, Neuro‐Quality of Life, and urine angiogenic factors over a two‐year period. Results Cognitive Neuroscore worsened over time for children aged 0–2 years. Male sex was associated with worsening Cognitive Function Neuroscore during the study. Age of seizure onset before 2 years was strongly associated with worse Neuroscore. Children with SWS had low Neuro‐Quality of Life related to cognitive function. Seizure severity, male sex, and earlier age of seizure onset were associated with worse Neuro‐Quality of Life in school‐aged children. Children with SWS have elevated basic fibroblast growth factor in their urine compared with controls, whereas higher vascular endothelial growth factor was associated with better Neuroscore. Interpretation This study is the first multicenter, prospective, and longitudinal study of people with SWS. It identifies significant clinical prognostic factors such as age of seizure onset and male sex, informs symptom progression over time by age group, and suggests that further study of angiogenic mechanisms and potential biomarkers are needed.

Background: Postcontrast magnetic resonance imaging (MRI), obtained under anesthesia, is often used to evaluate brain parenchymal and vascular abnormalities in young children, including those with Sturge-Weber syndrome. However, anesthesia and contrast administration may carry risks. We explored the feasibility and potential diagnostic value of a noncontrast, nonsedate MRI acquisition in Sturge-Weber syndrome children and their siblings with a wide range of cognitive and behavioral functioning. Methods: Twenty children (10 with Sturge-Weber syndrome and 10 healthy siblings; age: 0.7-13.5 years) underwent nonsedate 3-tesla (T) brain MRI acquisition with noncontrast sequences (including susceptibility-weighted imaging) prospectively along with neuropsychology assessment. All images were evaluated for quality, and MRI abnormalities identified in the Sturge-Weber syndrome group were compared to those identified on previous clinical pre- and postcontrast MRI. Results: Nineteen participants (95%) completed the MRI with good (n = 18) or adequate (n = 1) quality, including all children with Sturge-Weber syndrome and all 5 children ≤5 years of age. The Sturge-Weber syndrome group had lower cognitive functions than the controls, and both groups had several children with behavioral issues, without an apparent effect on the success and quality of the MR images. Susceptibility-weighted imaging detected key venous vascular abnormalities and calcifications and, along with the other noncontrast sequences, provided diagnostic information comparable to previous clinical MRI performed with contrast administration under anesthesia. Conclusion: This study demonstrates the feasibility and the potential diagnostic value of a nonsedate, noncontrast MRI acquisition protocol in young children including those with cognitive impairment and/or behavioral concerns. This approach can facilitate clinical trials in children where safe serial MRI is warranted. [ABSTRACT FROM AUTHOR]

Objective: This study was undertaken to estimate incidence of rare epilepsies and compare with literature. Methods: We used electronic health record text search to identify children with 28 rare epilepsies in New York City (2010–2014). We estimated cumulative incidence and compared with literature. Results: Eight of 28 rare epilepsies had five or more prior estimates, and our measurements were within the published range for all. The most common were infantile epileptic spasms syndrome (1 in 2920 live births), Lennox–Gastaut syndrome (1 in 9690), and seizures associated with tuberous sclerosis complex (1 in 14 300). Fifteen of 28 had fewer than five prior estimates, and of these, we provided additional estimates for early infantile developmental and epileptic encephalopathy (1 in 32 700), epilepsy with myoclonic–atonic seizures (1 in 34 100), Sturge–Weber syndrome plus seizures/epilepsy (1 in 40 900), epilepsy in infancy with migrating focal seizures (1 in 54 500), Aicardi syndrome plus seizures/epilepsy (1 in 71 600), hypothalamic hamartoma with seizures (1 in 225 000), and Rasmussen syndrome (1 in 450 000). Five of 28 rare epilepsies had no prior estimates, and of these, we provided a new estimate for developmental/epileptic encephalopathy with spike‐and‐wave activation in sleep and/or continuous spikes and waves during sleep (1 in 34 100). Data were limited for the remaining 12 rare epilepsies, which were all genetic epilepsies, including PCDH19, CDKL5, Alpers disease, SCN8A, KCNQ2, SCN2A, GLUT1 deficiency, Phelan‐McDermid syndrome, myoclonic epilepsy with ragged‐red fibers, dup15q syndrome, ring chromosome 14, and ring chromosome 20. Significance: We estimated the incidence of rare epilepsies using population‐based electronic health record data and literature review. More research is needed to better estimate the incidence of genetic epilepsies with nonspecific clinical features. Electronic health records may be a valuable data source for studying rare epilepsies and other rare diseases, particularly as genetic testing becomes more widely adopted. [ABSTRACT FROM AUTHOR]

Background: Sturge–Weber syndrome (SWS) is a neurocutaneous disorder for which the neurological aspects, particularly headaches, remain poorly understood, despite significantly affecting morbidity. The present study aimed to elucidate the prevalence, characteristics and treatment strategies, as well as explore the pathogenesis of headaches, in SWS. Methods: Using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, we systematically reviewed observational studies, case reports and series from eight databases (Cochrane Library, EBSCO, Embase, Medline, PubMed, Science Direct, Scopus and Web of Science), published from 1978 to 2023, to investigate the prevalence, characteristics, medication response and pathogenic theories of headaches in SWS. Results: The review analyzed 48 studies, uncovering headache prevalence between 37% and 71%. Migraine-like headache affected up to 52% of individuals. Prophylactic and acute treatments included non-steroidal anti-inflammatory drugs, triptans and antiepileptic drugs, despite the lack of established guidelines. Life-threatening headaches in SWS are uncommon, typically accompanied by other neurological symptoms. The pathogenesis of headaches in SWS is considered to involve venous congestion and neuronal hyperexcitability linked to leptomeningeal angiomas. Conclusions: Headaches occur more frequently in individuals with SWS than in the general population. Despite symptoms meeting migraine criteria, these headaches should be considered secondary to vascular conditions. Implementing acute and prophylactic treatment is advised to reduce the impact on patients' lives. [ABSTRACT FROM AUTHOR]

Prevalence of concurrent Phacomatosis Pigmentovascularis (PPV)and Sturge-Weber syndrome (SWS) is unknown due to its rarity and sporadic occurrence. In this case report, we present a rare case of bilateral glaucoma in an infant with PPV and SWS. A three-month old male infant presented with hazy cornea and visible black spots in the upper sclera and presented with intraocular pressure (IOP) of 40 and 52 mmHg in the left and right eye, respectively. Trabeculectomy-Trabeculotomy for both eyes was done which initially decreased IOP. However, high IOP recurred, and the patient was treated with topical medication. At one year follow-up, the patient had normal IOP and was responsive to light and object. Our case is a rare presentation of concurrent SWS, PPV, and bilateral glaucoma. The potential systemic comorbidities of this condition highlights that it is imperative that these patients are diagnosed early, treated promptly, and are monitored periodically.

Sturge-Weber syndrome is a rare, sporadic, progressive neurocutaneous condition that presents with congenital hamartomatous malformations, epilepsy, and a variety of facial symptoms. We discussed a rare case of an eighteen-year-old female child who came to our neurology department with status epilepticus, mental impairment, and a port-wine in the lateral left side of her face. We diagnosed Sturge-Weber syndrome after a thorough neurological and radiological evaluation. The purpose of presenting this case is to illustrate both the characteristic presentation and the complications associated with managing Sturge-Weber syndrome. [ABSTRACT FROM AUTHOR]

Background: Sturge-Weber syndrome (SWS) is a complex rare genetic neuro-cutaneous disorder characterized by the presence of a port-wine stain, ophthalmic and intracranial angiomatosis leading to seizures, ocular, and oral abnormalities. Case Presentation: We report a 39-year-old, non-diabetic, non-hypertensive female refugee who presented initially with heart failure due to anemia for which she received blood transfusions. Later on admission, she developed multiple focal to bilateral seizures, severe irritability, aphasia, and right-sided hemiplegia, leading to admission to the ICU. A repeat medical history and examination revealed a faint left-sided ophthalmic port-wine stain that was initially unnoticed and a remote history of unprovoked seizures 20 years ago. Imaging revealed parietal calcifications and confirmed the diagnosis of SWS. Thus, a multidisciplinary approach was taken to fully understand the patient's diagnosis and determine a treatment strategy, involving consultations with the neurology, ophthalmology, otolaryngology, and physiotherapy departments. Successful seizure control was achieved by administering IV phenytoin for 3 days and the up-titrating of oral carbamazepine to 1g daily through a nasogastric tube. Unfortunately, due to the unavailability of personnel or resources, other important assessments for patients with SWS, such as advanced neuroimaging, psychiatric, plastic and neuro-surgery evaluations, as well as dentistry reviews, could not be conducted. Conclusion: This case highlights the rare occurrence of adult-onset seizures in an undiagnosed SWS and their re-emergence after almost two decades without anti-seizure medications. It also highlights the importance of a comprehensive history and clinical examination, as this patient's diagnosis of SWS could have been missed if she had not experienced seizures on admission. Our study also demonstrates the challenges associated with managing such a complex condition in settings with limited resources. [ABSTRACT FROM AUTHOR]

Key Clinical Message This report presents a 14‐year‐old male with seizures and facial port‐wine stains, who upon further evaluation was found to have SWS. Early diagnosis and consistent treatment of Sturge–Weber syndrome in children are essential to prevent seizures and improve quality of life. Anti‐seizure medications play a crucial role in preventing and controlling seizures.

However, significant subretinal changes may also result following this method of treatment.

Sturge-Weber syndrome (SWS) is a rare congenital disorder associated with systemic vascular malformations characterized by port-wine stains, epilepsy, and glaucoma. Patients with SWS can develop stroke-like symptoms such as hemiparesis. We report a case of a 63-year old woman with SWS who developed left-sided hemiparesis and was finally diagnosed with myelin-oligodendrocyte glycoprotein (MOG) antibody-positive encephalitis. Brain magnetic resonance imaging (MRI) revealed right-dominant bilateral leptomeningeal enhancement, thickened dura mater, and a cerebellar lesion. Cerebrospinal fluid (CSF) examination showed pleocytosis. Both serum and CSF proved positive for MOG antibodies. The patient recovered immediately after intravenous methylprednisolone administration. SWS and MOG antibody-positive encephalitis share similar clinical findings of stroke-like symptoms and leptomeningeal enhancement on MRI. However, MOG antibody-positive encephalitis is highly steroid-responsive in most cases. If a patient with SWS develops stroke-like symptoms accompanied by abnormal CSF findings or subtentorial lesions, testing for MOG antibodies should be considered.

Abstract Background Ninety percent of infants with Sturge–Weber syndrome (SWS) brain involvement have seizure onset before 2 years of age; early‐onset seizures are associated with worse neurological outcome. Presymptomatic treatment before seizure onset may delay seizure onset and improve outcome, as has been shown in other conditions with a high risk of developing epilepsy, such as tuberous sclerosis complex. The electroencephalogram (EEG) may be a biomarker to predict seizure onset. This retrospective clinical data analysis aims to assess the impact of presymptomatic treatment in SWS. Methods This two‐center, Institutional Review Board–approved, retrospective study analyzed records from patients with SWS brain involvement. Clinical data recorded included demographics, age of seizure onset (if present), brain involvement extent (unilateral versus bilateral), port‐wine birthmark (PWB) extent, family history of seizures, presymptomatic treatment if received, Neuroscore, and antiseizure medications. EEG reports prior to seizure onset were analyzed. Results Ninety‐two patients were included (48 females), and 32 received presymptomatic treatment outside of a formal protocol (five aspirin, 16 aspirin and levetiracetam; nine aspirin and oxcarbazepine, two valproic acid). Presymptomatically treated patients were more likely to be seizure‐free at 2 years (15 of 32, 47% versus 7 of 60, 12%; p

Objectives We aimed to investigate the clinicopathologic features of and genetic changes in Sturge-Weber syndrome (SWS) in patients with refractory epilepsy. Methods Clinical data were retrospectively analyzed. H&E and immunohistochemistry were performed to assess pathologic changes. Targeted amplicon sequencing was applied to investigate the somatic GNAQ (c.548G>A) mutation. The potential predictors of seizure outcomes were estimated by univariate and multivariate statistical analyses. Results Forty-eight patients with SWS and refractory epilepsy were enrolled. According to the imaging data and pathologic examination, ipsilateral hippocampal sclerosis (HS), calcification of leptomeningeal arteries, and focal cortical dysplasia were found in 14 (29.2%), 31 (64.6%), and 37 (77.1%) patients, respectively. A high frequency of GNAQ alteration was detected in both cerebral cortex (57.7%) and ipsilateral hippocampus (50.0%) from patients with SWS. During follow-up, 43 of 48 patients (85.4%) had achieved seizure control (Engel class I). Statistically, HS signs on imaging were found to be independent predictors of unfavorable seizure outcomes (P =.015). Conclusions Calcification of leptomeningeal arteries, focal cortical dysplasia, and GNAQ alteration are common features in SWS pathology. Patients with refractory epilepsy caused by SWS can achieve satisfactory seizure control after surgery, but seizure control was compromised in patients with comorbid HS. [ABSTRACT FROM AUTHOR]

Background: Sturge–Weber syndrome (SWS) is a rare congenital neurocutaneous disorder characterized by the simultaneous presence of both cutaneous and extracutaneous capillary malformations. SWS usually presents as a facial port-wine birthmark, with a varying presence of leptomeningeal capillary malformations and ocular vascular abnormalities. The latter may lead to significant neurological and ocular morbidity such as epilepsy and glaucoma. SWS is most often caused by a somatic mutation involving the G protein subunit alpha Q or G protein subunit alpha 11 gene causing various alterations in downstream signaling pathways. We specifically conducted a comprehensive review focusing on the current knowledge of clinical practices, the latest pathophysiological insights, and the potential novel therapeutic avenues they provide. Data sources: A narrative, non-systematic review of the literature was conducted, combining expert opinion with a balanced review of the available literature. A search of PubMed, Google Scholar and Embase was conducted, using keywords "Sturge–Weber Syndrome" OR "SWS", "Capillary malformations", "G protein subunit alpha 11" OR "G protein subunit alpha Q". Results: One of the hallmark features of SWS is the presence of a port-wine birthmark at birth, and forehead involvement is most indicative for SWS. The most common ocular manifestations of SWS are glaucoma and choroidal hemangioma. Glaucoma presents in either in infancy (0–3 years of age) or later in life. Neurological complications are common in SWS, occurring in about 70%–80% of patients, with seizures being the most common one. SWS significantly impacts the quality of life for patients and their families, and requires a multidisciplinary approach for diagnosis and treatment. Currently, no disease-modifying therapies exist, and treatment is mostly focused on symptoms or complications as they arise. Conclusions: SWS remains a complex and heterogeneous disorder. Further research is needed to optimize diagnostic and therapeutic strategies, and to translate insights from molecular pathogenesis to clinical practice. [ABSTRACT FROM AUTHOR]

The authors report a case of a 5-month-old full-term infant with chronic conjunctival redness and elevated intraocular pressure in the right eye. Magnetic resonance imaging ruled out leptomeningeal angiomatosis. Despite lacking a typical port-wine mark, the diagnosis of Sturge-Weber syndrome was established based on specific observations in the right eye that involved unilateral vascular glaucoma. These findings included Haab striae, a larger axial length measurement, an increased number of episcleral vessels with blood in Schlemm canal, and a thicker choroid in the macular region. This is the first reported pediatric case with these specific ocular manifestations in the absence of facial angioma, highlighting the need for awareness among clinicians to avoid misdiagnosis and facilitate proper management.

Capillary malformation (CM), or port wine birthmark, is a cutaneous congenital vascular anomaly that occurs in 0.1%-2% of newborns. Patients with a CM localized on the forehead have an increased risk of developing a neurocutaneous disorder called encephalotrigeminal angiomatosis or Sturge-Weber syndrome (SWS), with complications including seizure, developmental delay, glaucoma, and vision loss. In 2013, a groundbreaking study revealed causative activating somatic mutations in the gene (GNAQ) encoding guanine nucleotide-binding protein Q subunit α (Gαq) in CM and SWS patient tissues. In this Review, we discuss the disease phenotype, the causative GNAQ mutations, and their cellular origin. We also present the endothelial Gαqrelated signaling pathways, the current animal models to study CM and its complications, and future options for therapeutic treatment. Further work remains to fully elucidate the cellular and molecular mechanisms underlying the formation and maintenance of the abnormal vessels. [ABSTRACT FROM AUTHOR]

Objectives: The profile of seizures in neurocutaneous syndromes is variable. We aimed to define the characteristics of epilepsy in children with neurocutaneous syndromes. Materials and Methods: Cross-sectional study over 18 months at a tertiary care pediatric hospital, including children with neurocutaneous syndromes aged between 1 and 15 years, using the 2017-International League Against Epilepsy classification. Results: In 119 children with neurocutaneous syndromes, 94 (79%) had epilepsy. In eight children with neurofibromatosis one with epilepsy, 5 (62.5%) had generalized motor tonic-clonic seizures, 1 (12.5%) had generalized motor epileptic spasms, 1 (12.5%) had generalized motor automatism, and 1 (12.5%) had a focal seizure. In 69 children with tuberous sclerosis complex with epilepsy, 30 (43.5%) had generalized motor epileptic spasms, 23 (33.3%) had focal seizures, and nine (13.0%) had generalized motor tonic-clonic seizures. In 14 children with Sturge-Weber syndrome with epilepsy, 13 (92.8%) had focal seizures, and 1 (7.2%) had generalized motor tonic seizures. Statistically significant associations were found between epilepsy and intellectual disability (P = 0.02) and behavioral problems (P = 0.00). Conclusion: Profiling seizures in children with neurocutaneous syndromes are paramount in devising target-specific treatments as the epileptogenesis in each syndrome differs in the molecular pathways leading to the hyperexcitability state. Further multicentric studies are required to unravel better insights into the epilepsy profile of neurocutaneous syndromes. [ABSTRACT FROM AUTHOR]

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.

Background Sturge–Weber syndrome (SWS) is a rare condition associated with a GNAQ gene mutation, which affects neural crest cells. A pulsed dye laser (PDL) is a first-line therapy for SWS, but its outcomes are worse than those in patients with port-wine stains (PWS). Photodynamic therapy (PDT) is a promising therapeutic option for PWS. However, its use for PWS associated with SWS has rarely been studied. Aims To investigate the therapeutic and adverse effects of photodynamic therapy in treating SWS–associated PWS. Methods Patients with SWS and matched patients with large size facial PWS were included in this study. Both colorimetric assessment and visual evaluation were conducted to evaluate patients' responses to treatment. Results Colorimetric assessment (blanching rate) and visual evaluation (scores of colour improvement) showed that after two PDT treatments, the SWS and PWS groups had similar treatment responses (21.2% vs. 29.8%; 3.39 vs. 3.65; P = 0.18, P = 0.37). However, there was a significant difference in efficacy between patients with SWS with and without a treatment history (12.4 and 34.9%, respectively; P = 0.02), as well as between patients with lesions located on the central and lateral faces (18.5 and 36.8%, respectively; P = 0.01). Both the SWS and PWS groups experienced minor adverse effects, and the frequency of these effects was not significantly different between the two groups. Limitation The study was limited by a small sample size and the possibility of later onset of glaucoma. In addition, false-negative magnetic resonance imaging screening results for SWS could not be ruled out due to the young age of some participants. Conclusion Photodynamic therapy is a safe and effective therapeutic option for SWS–associated PWS. Patients without a treatment history, and lesions on the lateral face, responded well, demonstrating good efficacy. [ABSTRACT FROM AUTHOR]

Sturge-Weber syndrome (SWS) is a neurocutaneous disorder that classically presents with a triad of vascular anomalies affecting the skin, eyes, and brain. Previously, the trigeminal nerve distribution of a port-wine birthmark (PWB) of the face was used to identify risk of SWS. However, recent evidence has demonstrated that PWBs are vascular, not neurologic, in embryologic origin, and facial PWBs at highest risk for the brain involvement of SWS involve the forehead location. Furthermore, a PWB involving the upper or lower eyelid carries a risk of glaucoma, which requires lifelong monitoring. The gold standard of treatment for PWB is the pulsed dye laser, which has many advantages when started as early as possible in infancy. In this review, we discuss the locations of facial PWBs at risk for neurologic and ophthalmologic complications, the differential diagnosis of facial vascular birthmarks, recommendations for patient referral(s) when needed, and the advantages of early laser therapy when desired for the PWB. We also provide additional resources for pediatricians to support patients and their families.

Objective: We aimed to evaluate determinants of functional outcome after pediatric hemispherotomy in a large and recent multicenter cohort. Methods: We retrospectively investigated the functional outcomes of 455 children who underwent hemispherotomy at 5 epilepsy centers in 2000–2016. We identified determinants of unaided walking, voluntary grasping with the hemiplegic hand, and speaking through Bayesian multivariable regression modeling using missing data imputation. Results: Seventy‐five percent of children were seizure‐free, and 44% stopped antiseizure medication at a 5.1‐year mean follow‐up (range = 1–17.1). Seventy‐seven percent of children could walk unaided, 8% could grasp voluntarily, and 68% could speak at the last follow‐up. Children were unlikely to walk when they had contralateral magnetic resonance imaging (MRI) abnormalities (40/73, p = 0.04), recurrent seizures following hemispherotomy (62/109, p = 0.04), and moderately (50/61, p = 0.03) or severely impaired (127/199, p = 0.001) postsurgical intellectual functioning, but were likely to walk when they were older at outcome determination (p = 0.01). Children were unlikely to grasp voluntarily with the hand contralateral to surgery when they had Rasmussen encephalitis (0/61, p = 0.001) or Sturge–Weber syndrome (0/32, p = 0.007). Children were unlikely to speak when they had contralateral MRI abnormalities (30/69, p = 0.002) and longer epilepsy duration (p = 0.01), but likely to speak when they had Sturge–Weber syndrome (29/35, p = 0.01), were older at surgery (p = 0.04), and were older at outcome determination (p < 0.001). Interpretation: Etiology and bilaterality of structural brain abnormalities were key determinants of functional outcome after hemispherotomy. Longer epilepsy duration affected language outcomes. Not surprisingly, walking and talking ability increased with older age at outcome evaluation. ANN NEUROL 2024;95:377–387 [ABSTRACT FROM AUTHOR]

Objective: In this study, we aimed to discuss the neurological characteristics of our cases diagnosed with Sturge-Weber Syndrome with literature information. Material and Methods: The files of 12 patients diagnosed with Sturge-Weber syndrome between October 2013 and September 2023 at Bursa Uludağ University Faculty of Medicine Child Neurology Clinic were retrospectively evaluated. Results: Of the 12 patients diagnosed with Sturge-Weber syndrome, 7 (58.3%) were boys and 5 (41.7%) were girls. The median age of the cases was 143 months (minimum: 13, maximum: 251 months), and the median age at first presentation was 15.5 months (minimum: 0.13-maximum: 76 months). Considering the complaints at first admission, 6 (50%) cases presented with seizures, 4 cases complained of facial spots (33.3%), and 2 (16.7%) cases presented with seizures and facial spots. Considering the age of the first seizure, 7 out of 10 cases with seizures were under two years old. When the brain magnetic resonance imagines (MRI) of the patients were evaluated, MRIs in 3 (25%) cases were normal, leptomeningeal vascular anomaly or contrast enhancement in 7 (58.3%) cases, cerebral parenchymal obliteration/atrophy in 7 (58.3%) cases, cortical/gyral abnormalities in 6 (50%) cases. Calcification, transparenchymal vein dilatation/enlarged venous structures in 5 (41.7%) cases, enlarged choroid plexus in 2 (16.7%) cases, and thickened calvarium in 1 (8.3%) case were detected. Conclusion: SturgeWeber syndrome is a rare but multisystemic disease that affects many systems, characterized by leptomeningeal vascular malformation in the brain, port wine birthmark, and abnormal blood vessels in the eye.

Purpose: To report 6 cases of diffuse choroidal hemangioma in children treated with iodine-125 plaque brachytherapy at a single tertiary care center. Methods: Retrospective case series. Results: Six pediatric patients diagnosed with diffuse choroidal hemangioma were included in the study. Preplaque visual acuity ranged from 20/150 to no light perception. All patients had extensive serous retinal detachment at presentation. An iodine-125 radioactive plaque was placed on the affected eye to administer a dose of 34.2-42.1 Gy to the tumor apex over a median of 4 days. Tumor regression and subretinal fluid resolution were observed in all eyes within 17 months of treatment. Visual acuity improved in two patients. Radiation-induced cataract and subretinal fibrosis were documented in one case, and one patient developed radiation retinopathy. No patients developed neovascular glaucoma within the follow-up time of 12-65 months. Conclusion: Iodine-125 plaque radiotherapy is an effective option for diffuse choroidal hemangioma, although there is a risk for radiation-induced complications. [ABSTRACT FROM AUTHOR]

Sturge–Weber syndrome (SWS) is a rare neurocutaneous disorder that is characterized by a segmental dermatomal facial port-wine stain birthmark and is frequently accompanied by ipsilateral brain and eye abnormalities. We present a case of a patient with SWS who exhibited hypogonadotropic hypogonadism, growth hormone (GH) deficiency, and central hypothyroidism at the age of 20 despite the absence of radiographic findings in the pituitary and hypothalamus. A 20-year-old male with SWS with epilepsy and Klippel–Trenaunay syndrome presents with delayed pubertal development, short stature, and obesity. Upon further examination, he was found to have biochemical and clinical evidence of hypogonadism, hypothyroidism, and GH deficiency. A pituitary MRI displayed no abnormalities of the pituitary or hypothalamus. Treatment with testosterone cypionate and levothyroxine was initiated. Despite successful pubertal induction, IGF-1 levels have remained low and treatment with recombinant human growth hormone (rhGH) is now being considered for metabolic benefits. This case emphasizes the importance of endocrine evaluation and treatment of hormonal deficiencies in patients with SWS despite the absence of radiographic findings. [ABSTRACT FROM AUTHOR]

Purpose: Sturge-Weber syndrome (SWS) is a developmental disorder with venous hypertension and associated tissue responses including pial angiomatosis, cortical calcifications, and cerebral atrophy. Arterial spin-labeled (ASL) perfusion is an advanced MR sequence which can assess perfusion, without the need for contrast. We systematically evaluated the potential benefits of using ASL in Sturge-Weber syndrome, to determine the extent of intracranial perfusion abnormality and stage of disease, relevant for prognostication and surgical planning. Methods: Two pediatric neuroradiologists retrospectively evaluated ASL perfusion imaging of 31 children with confirmed SWS and recorded the presence of hyper-perfusion, hypo-perfusion, or normal perfusion. The presence and distribution of ASL abnormality were compared against the presence and side of atrophy/calcification and pial angiomatosis on standard MR sequences. Results: Thirty-one children (52% female, median age 16.7 months) with SWS had ASL imaging. Seven (23%) had hyper-perfusion, 15 (48%) had hypo-perfusion, and 9 (29%) had no perfusion abnormalities. ASL perfusion abnormality matched the location of SWS findings on conventional imaging in 86% (19/22). ASL demonstrated statistically significant increased perfusion in the early stage of the disease and decreased perfusion when there was atrophy. The parietal lobe was involved in 86% of cases. Conclusion: ASL perfusion imaging is an advanced technique which may contribute to earlier diagnosis and more accurate prognostication of Sturge-Weber syndrome, helping guide management and potential surgical planning.

Introduction Vascular anomalies are a spectrum of disorders, including vascular tumors and malformations, that often require multispecialty care. The rarity and variety of these lesions make diagnosis, treatment, and management challenging. Despite the recognition of the medical complexity and morbidity associated with vascular anomalies, there is a general lack of education on the subject for pediatric primary care and subspecialty providers. A needs assessment and the lack of an available standardized teaching tool presented an opportunity to create an educational workshop for pediatric trainees using the POGIL (process-oriented guided inquiry learning) framework. Methods We developed a 2-hour workshop consisting of an introductory didactic followed by small- and large-group collaboration and case-based discussion. The resource included customizable content for learning assessment and evaluation. Residents completed pre- and posttest assessments of content and provided written evaluations of the teaching session. Results Thirty-four learners in pediatrics participated in the workshop. Session evaluations were positive, with Likert responses of 4.6-4.8 out of 5 on all items. Pre- and posttest comparisons of four content questions showed no overall statistically significant changes in correct response rates. Learners indicated plans to use the clinical content in their practice and particularly appreciated the interactive teaching forum and the comprehensive overview of vascular anomalies. Discussion Vascular anomalies are complex, potentially morbid, and often lifelong conditions; multispecialty collaboration is key to providing comprehensive care for affected patients. This customizable resource offers a framework for trainees in pediatrics to appropriately recognize, evaluate, and refer patients with vascular anomalies.

Background: Circumscribed choroidal hemangioma (CCH), a rare benign tumor, poses significant risks to vision due to its proximity to the macula, with epidemiology varying from one population to another. Objectives: The present article emphasizes the need for prevalence studies on CCH in Iraq. Methods: In June 2023, a literature review was conducted on PubMed, followed by a secondary analysis of patients' demographic data from diverse populations and ethnic groups worldwide. Results: The secondary literature analysis revealed demographic variations in CCH, including age and gender (male-to-female) ratios, and across different populations. The exact prevalence remains unclear, particularly in Iraq, due to limited data and asymptomatic cases. Accurate diagnosis through imaging techniques is crucial for symptomatic cases, with treatment modalities like PDT available. Economic challenges persist in Iraq, highlighting the need for collaboration between healthcare and government sectors. Conclusion: The lack of CCH prevalence studies in Iraq impedes understanding and management, impacting ophthalmology care for Iraqi patients. Addressing this gap through research can benefit local healthcare authorities and provide essential data for the Middle East and other regions worldwide

Key Clinical Message Sturge–Weber syndrome (SWS) is a neurocutaneous syndrome characterized by angiomas. This report presents airway management using submental intubation in sagittal split ramus osteotomy under general anesthesia and aimed to explore better anesthetic management for avoiding the rupture of angiomas in a patient with SWS.

We report a case of 6-year-old boy presented with dimness of vision having a past history of recurrent seizure for last four years and was found to have glaucoma in both eyes. He also had port-wine stain over both sides of face and hypertrophy of left hand and leg, venous prominence over abdominal wall and chest. CT scan shows left-sided angiomatosis in brain and venacaval anomalous connections in abdomen. This case reveals a very rare overlap between SWS and KTS presented with bilateral port-wine stain and bilateral glaucoma.

Port-wine birthmarks (PWBs) are caused by somatic, mosaic mutations in the G protein guanine nucleotide binding protein alpha subunit q (GNAQ) and are characterized by the formation of dilated, dysfunctional blood vessels in the dermis, eyes, and/or brain. Cutaneous PWBs can be treated by current dermatologic therapy, like laser intervention, to lighten the lesions and diminish nodules that occur in the lesion. Involvement of the eyes and/or brain can result in serious complications and this variation is termed Sturge-Weber syndrome (SWS). Some of the biggest hurdles preventing development of new therapeutics are unanswered questions regarding disease biology and lack of models for drug screening. In this review, we discuss the current understanding of GNAQ signaling, the standard of care for patients, overlap with other GNAQ-associated or phenotypically similar diseases, as well as deficiencies in current in vivo and in vitro vascular malformation models.
