Sturge-Weber syndrome

A case report of macular coloboma as an ocular clinical feature in Sturge Weber Syndrome

INTRODUCTION AND IMPORTANCE

Sturge Weber Syndrome (SWS) is a congenital neurocutaneous disorder that affects several organs. Abnormal ocular findings are typically on the same side as the SWS. These changes can affect various parts of the eye, including the eyelid, front chamber, cornea, choroid, and retina. To our knowledge, this is first documented case in the peer review literature of foveal Coloboma in SWS. This case report highlights this important finding in special cases of secondary open angle glaucoma related to SWS.

CASE PRESENTATION

A 5 month old baby girl, known to have SWS. Presented to our ER with high Intraocular pressure (IOP). Upon external examination, the child had port wine stain on the left side of her face. The dilated fundus exam revealed foveal coloboma which is not known as ocular clinical feature in cases of SWS. The fundus exam also showed diffuse choroidal hemangioma nasal to the disc. The case was managed with Micropulse Cyclophotocoagulation. The IOP was stable during 2 years of follow up.

DISCUSSION

Choroidal colobomas can be vision threatening due macular and optic disc involvement. Choroidal colobomas increase the risk of retinal detachment, and subfoveal choroidal neovascularization. They can occur as a part of genetic disorders such as CHARGE syndrome. In our case the foveal location of the coloboma and the anisometropic amblyopia both led to the decrease of vision and amblyopia in that eye.

CONCLUSIONS

Reporting a macular coloboma in a patient with SWS. After conducting a literature review on foveal Coloboma utilizing PubMed, Google Scholar, Cochrane Library and ScienceDirect using the key words (Foveal coloboma, Macula coloboma, Sturge Weber Syndrome), we did not find any prior reports of foveal Coloboma in SWS.

FLAIR hyperintensity in the subarachnoid space: Main differentials

The fluid-attenuated inversion recovery (FLAIR) sequence forms part of the vast majority of current diagnostic protocols for brain MRI. This sequence enables the suppression of the signal from cerebrospinal fluid, facilitating the detection of disease involving the subarachnoid space. The causes of hyperintensity in the arachnoid space in this sequence can be divided into two main categories: hyperintensity due to disease and hyperintensity due to artifacts. Hyperintensity due to tumors, inflammation, vascular disease, or hypercellularity of the cerebrospinal fluid or hematic contents is well known. However, numerous other non-pathological conditions, mainly due to artifacts, that are also associated with this finding are a potential source of diagnostic errors.

Incidence of Sturge-Weber Syndrome and Risk of Secondary Glaucoma: A Nationwide Population-based Study Using a Rare Disease Registry

PURPOSE

To determine Sturge-Weber syndrome (SWS) incidence and secondary glaucoma risk.

DESIGN

Nationwide retrospective cohort study.

METHODS

The Korean National Health Insurance (NHI) claims database from 2002 to 2019 along with the registration-program database for rare intractable diseases (ie, the rare disease registry) were accessed to identify ophthalmologist/neurologist-confirmed SWS patients. SWS incidence was estimated in a same-birth-year population (ie, a birth cohort) from 2002 to 2009. Among the SWS patients born between 2002 and 2019, the incidence of SWS-associated glaucoma was estimated.

RESULTS

During the 18-year observational period, a total of 1049 patients were registered as SWS. The mean birth-cohort SWS incidence was 3.08 (95% CI 2.52-3.64) per 100 000 people per year, with an approximate female-to-male ratio of 0.97:1. Among the 217 SWS patients born between 2002 and 2019, secondary glaucoma arose in 18 (8.3%) cases, including 12 males (66.7%). Among these 18 SWS-associated glaucoma cases, 15 (83.3%) were diagnosed before 1 year of age, and the other 3 (16.7%) between age 1 and 2 years. Among the 660 SWS patients under age 40 years during the study period, SWS-associated glaucoma was identified in 79 (12.0%) cases. Neurologic manifestations such as epilepsy, hemiparesis, and mental retardation did not significantly differ between SWS patients with and those without secondary glaucoma.

CONCLUSIONS

This study identified birth-cohort SWS incidence and determined secondary-glaucoma risk in a population of East Asian ethnicity. These data could help to promote better understanding of the epidemiologic features of SWS patients.

Clinical characteristics of infants with port-wine stain and glaucoma secondary to Sturge-Weber Syndrome

BACKGROUND

Sturge-Weber Syndrome (SWS) is a rare disease involving the eye, skin, and brain. Port-wine stain (PWS) and glaucoma are common clinical manifestations. This study analysed the clinical characteristics of infants with PWS and glaucoma secondary to SWS.

METHODS

Children with PWS and glaucoma secondary to SWS were enrolled. Data were extracted from ophthalmic and systemic examination findings. Ocular examinations included intraocular pressure, anterior segment and fundus examination, and ocular A-scan and B-scan ultrasonography.

RESULTS

Fifty-seven patients were included, with a mean age of 9.9 ± 11.9 months, and 34 (59.6%) patients were male. In all, 61 eyes were diagnosed with glaucoma. Forty-one patients (71.9%) had unilateral facial PWS and glaucoma occurred on the same side. Eight patients (14.0%) had Mongolian spots and ten patients (17.5%) had epilepsy. Corneal changes included corneal oedema (n = 36 eyes, 59.0%), corneal opacity (n = 15 eyes, 24.6%), and Haab lines (n = 13 eyes, 21.3%). Mean corneal diameter and thickness in the eyes with glaucoma was larger than those in the unaffected eyes (12.2 ± 0.7 mm vs 10.8 ± 0.6 mm, P < 0.001; 681.2 ± 106.4 µm vs 578.2 ± 58.2 µm, P < 0.001). The eyes with glaucoma had higher IOP and larger axial length and C/D ratio (19.3 ± 6.2 mmHg vs 11.6 ± 4.2 mmHg, P < 0.001; 21.23 ± 1.93 mm vs 19.68 ± 1.61 mm, P < 0.001; and 0.57 ± 0.18 vs 0.24 ± 0.15, P < 0.001). Thirty-three (57.9%) and 25 (43.9%) patients showed diffuse choroidal haemangioma (DCH) and conjunctival/episcleral haemangiomas, respectively. Ten patients (17.5%) showed iris anterior insertion or hyperpigmentation in the anterior chamber angles. Six of them had Mongolian spots at the same time.

CONCLUSIONS

Monocular glaucoma, DCH, and conjunctival/episcleral haemangiomas are common in SWS patients with PWS and glaucoma. Glaucomatous eyes have larger corneal diameter and axial length and thicker cornea. Patients with Mongolian spots have higher incidence of iris anterior insertion or hyperpigmentation in anterior chamber angle.

Choroidal hemangioma in Sturge Weber syndrome: Case series with confirmed tissue diagnosis

Introduction

Sturge-weber syndrome (SWS) is a rare condition that presents with a typical facial port-wine stain, neurological manifestations such as seizures, and ocular involvement by glaucoma and/or choroidal hemangioma. In this series we demonstrate the histopathological details of the primary ocular involvement as well as the late blinding secondary ocular changes.

Presentation of cases

Seven cases were included with the diagnosis of choroidal hemangioma in association with SWS (6 enucleations and one evisceration). Male to female ratio was 4:3. Age at enucleation/evisceration ranged from 25 to 68 years with a median of 42 years. Five cases had history of glaucoma (71.4%). Diffuse hemangioma was found in all (4 cavernous and 3 mixed cavernous/capillary type). Conjunctival and episcleral hemangiomas were found in 3/7. Iris neovascularization and retinal detachment were confirmed in 5/7 cases each (71%).

Discussion

Our demographic and histopathological findings parallel what was previously concluded in the literature about the lack of gender predilection in SWS, and the most common ocular presentations of glaucoma and choroidal hemangioma, which is mostly diffuse in nature. The hemangioma type was found to be mostly cavernous followed by mixed capillary and cavernous. We demonstrated late associated ocular changes such as cataract, iris neovascularization, exudative retinal detachment, retinal pigment epithelium hyperplasia/metaplasia, and optic nerve atrophy, all of which aid in the poor visual outcome in these patients.

Conclusion

Sturge-weber syndrome is a rare but visually disabling disease due to the associated ocular manifestations of glaucoma and choroidal hemangioma. Multidisciplinary approach because of the diverse presentation of this condition by pediatrician, neurologist, and ophthalmologist is essential with an attempt to preserve vision.

•

Sturge-weber syndrome (SWS) is a rare, condition manifesting with port-wine stains, seizures, glaucoma, and hemangiomas.

•

Diffuse choroidal hemangioma (DCH) is the typical ocular lesion in SWS.

•

We report 7 cases with histologically confirmed SWS-associated DCHs and their relevant visually disabling complications.

•

Early diagnosis and treatment are essential for improved visual outcome.

Case report: anti-N-Methyl-D-Aspartate receptor encephalitis and bilateral temporal calcifications

Background

In this study, we report a case of a young female who was hospitalized for seizures and diagnosed with anti–N-methyl-D-aspartate receptor (NMDAR) encephalitis.

Case presentation

The main feature of this patient was bilateral temporal calcifications detected by routine head computed tomography (CT). The co-existence of anti-NMDAR encephalitis and cerebral calcifications has not been reported. We supposed that the patient had an incomplete form of celiac disease (CD), epilepsy and cerebral calcifications syndrome (CEC). The patient's symptoms were alleviated by a series of treatments, and she remained stable during the follow-ups.

Conclusions

Our findings confirm the rarity co-existing anti-NMDAR encephalitis and cerebral calcifications. In future clinical work, we need to elucidate the relationship between anti-NMDAR encephalitis and cerebral calcifications, and the association between anti-NMDAR encephalitis and other co-existing autoimmune disorders.

Successful Reduction of Intraocular Pressure in a Patient with Glaucoma Secondary to Sturge-Weber Syndrome Using a Suprachoroidal Shunt

Aim

We present a case of successful reduction of intraocular pressure (IOP) in a patient with Sturge-Weber syndrome (SWS) and moderate open angle glaucoma using a suprachoroidal shunt.

Background

Patients with SWS glaucoma often have elevated episcleral venous pressure resulting in elevated IOP. This makes the conventional pathway for aqueous humor outflow a poor target for IOP reduction, yielding it difficult to treat. Medication and procedures that facilitate uveoscleral outflow have been more successful.

Case description

We present a case where a suprachoroidal shunt device (CyPass®) was used to reduce IOP in a patient with SWS. The IOP reduction has persisted for 12 months without complication or the requirement for topical prostaglandin analog use.

Conclusion

The uveoscleral pathway is a preferred target for IOP reduction in patients with elevated episcleral venous pressure. The CyPass device offers a promising ab interno minimally invasive glaucoma surgery (MIGS) approach to reduce IOP in cases where a pathologic pressure gradient exists in the trabecular meshwork.

Clinical significance

Glaucoma in patients with SWS has been historically difficult to treat. Previous surgical procedures that have been successful are more invasive and have required the creation of alternative drainage routes of aqueous humor. The CyPass device offers a promising less invasive option to reduce IOP in these patients.

Incidence of Sturge-Weber syndrome and associated ocular involvement in Olmsted County, Minnesota, United States

Background: Sturge-Weber syndrome (SWS) is a rare sporadic syndrome characterized by nevus flammeus (port-wine stain, PWS) in the trigeminal nerve distribution, diffuse choroidal hemangioma, and brain leptomeningeal hemangioma. We are unaware of previous reports of SWS incidence in the United States. This study investigated SWS incidence and associated ocular involvement in Olmsted County, Minnesota.Materials and methods: The Rochester Epidemiology Project database was used to identify SWS cases from January 1, 2000-December 31, 2017. Incidence of SWS was calculated using the Olmsted County census population. A literature review of studies investigating SWS-associated ocular involvement was also performed.Results: There were 13 patients with SWS in Olmsted County classified as type 1 (31%) or type 2 (69%). Age and sex-adjusted incidence of SWS was 0.19/100,000/year. Race was predominantly Caucasian (85%), with sex female (69%) or male (31%). All patients had PWS, mostly with unilateral distribution in the V1 and/or V2 region (85%). Two cases (15%) had associated Klippel-Trenaunay syndrome. The most common ocular features included: dilated episcleral vessels (46%), glaucoma (46%), retinal detachment (23%), DCH (7.7%), strabismus (31%), and refractive error (38%). PWS in the V1 distribution was associated with all cases of glaucoma, DCH, and neurological involvement. Severe visual impairment (>0.6 LogMAR, Snellen equivalent ≤20/100) was found in (23%) at final follow-up, and one patient (8%) required enucleation for uncontrolled glaucoma.Conclusions: SWS affects approximately 0.19/100,000/year in Olmsted County. Early diagnosis, intervention, lifelong follow-up, and multidisciplinary approach should be used to optimize systemic and ocular outcomes.

Combined cilioretinal artery and hemi-retinal vein occlusion in Sturge Weber syndrome: Expanding the clinical spectrum

A 9-year-old boy with the diagnosis of Sturge-Weber Syndrome, and port-wine stain involving the right side of the face, presented with acute visual loss of the right eye. Examination revealed a high intraocular pressure and a combined cilioretinal artery and inferior hemi-retinal vein occlusion in the right eye. Systemic work-up was negative. After controlling the intraocular pressure, gradual improvement of vision was noticed with simultaneous disappearance of signs of vascular occlusion.

Sturge Weber Syndrome: review of literature with case illustration

Sturge-Weber syndrome (SWS) also called as encephalotrigeminal angiomatosis, is a sporadically occurring rare neuro-cutaneous syndrome, characterized by vascular malformation with capillary venous angiomas involving face, choroidal layer of eye globe and leptomeninges responsible for ophthamological as well as neurological signs and symptoms. Authors report an interesting case, a six year old girl, who presented with seizures, facial port wine stain and normal psychomotor development. CT scan showed left cerebral hemiatrophy, left frontal and parieto occipital calcification with cortical calcification in left high frontal convexity. Cranial MRI scan also confirmed finding of left cerebral hemiatrophy and also revealed presence of gyriform cortical calcification, prominent flow voids seen in left basal ganglia. Her seizure is well controlled with antiepileptic medication. The pertinent literature is reviewed and management of such cases is discussed briefly.

Vascular Stains: Proposal for a Clinical Classification to Improve Diagnosis and Management

Vascular stains are a common reason for consultation in pediatric dermatology clinics. Although vascular stains include all vascular malformations, the term is most often used to refer to capillary malformations, but capillary malformations include a wide range of vascular stains with different clinical features, prognoses, and associated findings. The discovery of several mutations in various capillary malformations and associated syndromes has reinforced these differences, but clinical recognition of these different types of capillary vascular stains is sometimes difficult, and the multitude of classifications and confusing nomenclature often hamper the correct diagnosis and management. From our own experience and a review of the most relevant literature on this topic, we propose categorizing patients with capillary vascular stains into seven major clinical patterns: nevus simplex, port-wine stain, reticulated capillary malformation, geographic capillary malformation, capillary malformation-arteriovenous malformation (CM-AVM), cutis marmorata telangiectatica congenita, and telangiectasia. We also discuss the differential diagnosis of vascular stains as well as other conditions that can closely resemble capillary malformations and thus may potentially be misdiagnosed.

Ocular manifestations of Sturge-Weber syndrome: pathogenesis, diagnosis, and management

Sturge–Weber syndrome has been included in the group of phakomatoses that is characterized by hamartomas involving the brain, skin, and eyes. The characteristic facial port-wine stain, involving the first branch of the trigeminal nerve and the embryonic vasculature distribution in this area, leads to several ocular complications of the anterior segment and can involve the eyelids and conjunctiva. The posterior segment of the eyes is also affected with diffuse choroidal hemangiomas. However, the most frequent ocular comorbidity is glaucoma with a prevalence rate ranging from 30%–70%. Glaucoma is related to anterior chamber malformations, high episcleral venous pressure (EVP), and changes in ocular hemodynamics. Glaucoma can be diagnosed at birth, but the disease can also develop during childhood and in adults. The management of glaucoma in Sturge–Weber syndrome patients is particularly challenging because of early onset, frequently associated severe visual field impairment at the time of diagnosis, and unresponsiveness to standard treatment. Several surgical approaches have been proposed, but long-term prognosis for both intraocular pressure control and visual function remains unsatisfactory in these patients. Choroidal hemangiomas may also lead to visual impairment thorough exudative retinal detachment and macular edema. Treatment of exudative hemangioma complications is aimed at destructing the tumor or decreasing tumor leakage.

Mosaic Neurocutaneous Disorders and Their Causes

Neurocutaneous disorders are a heterogeneous group of conditions (mainly) affecting the skin [with pigmentary/vascular abnormalities and/or cutaneous tumours] and the central and peripheral nervous system [with congenital abnormalities and/or tumours]. In a number of such disorders, the skin abnormalities can assume a mosaic patterning (usually arranged in archetypical patterns). Alternating segments of affected and unaffected skin or segmentally arranged patterns of abnormal skin often mirror similar phenomena occurring in extra-cutaneous organs/tissues [eg, eye, bone, heart/vessels, lung, kidney and gut]. In some neurocutaneous syndromes the abnormal mosaic patterning involve mainly the skin and the nervous system configuring a (true) mosaic neurocutaneous disorder; or an ordinary trait of a neurocutaneous disorder is sometimes superimposed by a pronounced linear or otherwise segmental involvement; or, lastly, a neurocutaneous disorder can occur solely in a mosaic pattern. Recently, the molecular genetic and cellular bases of an increasing number of neurocutaneous disorders have been unravelled, shedding light on the interplays between common intra- and extra-neuronal signalling pathways encompassing receptor-protein and protein-to-protein cascades (eg, RAS, MAPK, mTOR, PI3K/AKT and GNAQ pathways), which are often responsible of the mosaic distribution of cutaneous and extra-cutaneous features. In this article we will focus on the well known, and less defined mosaic neurocutaneous phenotypes and their related molecular/genetic bases, including the mosaic neurofibromatoses and their related forms (ie, spinal neurofibromatosis and schwannomatosis); Legius syndrome; segmental arrangements in tuberous sclerosis; Sturge-Weber and Klippel-Trenaunay syndromes; microcephaly/megalencephaly-capillary malformation; blue rubber bleb nevus syndrome; Wyburn-Mason syndrome; mixed vascular nevus syndrome; PHACE syndrome; Incontinentia pigmenti; pigmentary mosaicism of the Ito type; neurocutaneous melanosis; cutis tricolor; speckled lentiginous syndrome; epidermal nevus syndromes; Becker's nevus syndrome; phacomatosis pigmentovascularis and pigmentokeratotica; Proteus syndrome; and encephalocraniocutaneous lipomatosis.

Anesthetic management of pediatric patients with Sturge-Weber syndrome: our experience and a review of the literature

INTRODUCTION

Sturge-Weber syndrome (SWS) is a rare sporadic congenital neurocutaneous syndrome which is characterized by vascular malformation involving the brain, face and eye. The anesthetic management is complicated by its localized as well as systemic manifestations, associated anomalies and difficult airway due to the presence of angiomas of the oral cavity and airway. We retrospective analyzed the perioperative anesthetic management of children with SWS undergoing ophthalmic surgery and reviewed the literature.

METHODS

Medical records and anesthetic charts of all the children with SWS who had undergone an ophthalmic procedure under general anesthesia during the past 6 years were reviewed. Information related to the demographic profile, preoperative evaluation, anesthetic techniques, and perioperative complications were collected and analyzed.

RESULTS

Forty children with SWS received general anesthesia for an ophthalmic procedure within the 6-year period. The median age of the children was 3 years. 30 (92.5%) children had facial port-wine staining, 10 (25%) had facial hypertrophy, 15 (37.5%) had a history of convulsion and 4 (10%) children had mental retardation. Inhalational induction was performed in 34 (85%) children (sevoflurane 82.8%). A laryngeal mask airway (LMA) and endotracheal tube were used in 32 (80%) and 5 (12.5%) cases, respectively. One patient had difficult mask ventilation and difficult LMA insertion. There was no significant problem in any of the other children.

CONCLUSION

Preoperative evaluation with airway assessment should be performed with the knowledge of local and systemic manifestation of the syndrome. Proconvulsant and anticonvulsant properties of the anesthetics, as well as drug interactions of antiepileptic medications should be considered when planning anesthesia. Avoiding a rise in intracranial and intraocular pressures, vigilant intraoperative monitoring and postoperative care are the key for conducting safe anesthesia in these children. For ophthalmic procedures, LMAs can be used for airway maintenance with minimal complications in children with SWS.

Diagnostic dilemma: Sturge-Weber syndrome, without facial nevus

Sturge-Weber syndrome (SWS), a rare sporadic neurocutaneous disease, is characterized by a congenital unilateral port-wine nevus affecting the area innervated by V1, ipsilateral leptomeningeal angiomatosis, and calcification in the occipital or frontoparietal region and glaucoma/vascular eye abnormality. Three types of SWS have been described in literature: Type I (classic) demonstrates facial and leptomeningeal angioma, often with glaucoma; type II has facial angioma and glaucoma, with no evidence of intracranial lesions; and type III (rarest) presents with only leptomeningeal angioma. Only a few cases of type III SWS have been reported. Here, we report a case of a seven-year-old boy with focal complex partial seizure, who was diagnosed with SWS without facial nevus. Recognition of this type of SWS is important, as our patient had been misdiagnosed and received inappropriate antiepileptic drugs for six years. We suggest that in the appropriate clinical scenario, the diagnosis of SWS without facial nevus should be considered before labelling idiopathic or cryptogenic localization-related epilepsy, and gadolinium-enhanced magnetic resonance imaging (MRI) should be done in clinically suspicious cases of SWS, without facial nevus.

Sturge-Weber Syndrome (Encephalotrigeminal Angiomatosis): Recent Advances and Future Challenges

Sturge-Weber syndrome (SWS) is a congenital, sporadically occurring, neurocutaneous syndrome that presents classically with port-wine stain, leptomeningeal angiomas, and glaucoma. The systemic implications of SWS are vast and involve not only ophthalmic manifestations but also dermatologic, neurologic, and oral manifestations. Neuroimaging, in particular, plays an important role in the diagnosis and management of this disease. Recent discoveries have been made regarding the genetic pathogenesis of SWS. In addition, recent advances have been made in the management of the 2 most common ophthalmic manifestations of SWS: diffuse choroidal hemangioma and glaucoma. Despite these new contributions to the field, many challenges still remain. The management of diffuse choroidal hemangioma is wide ranging and includes photodynamic therapy, brachytherapy, radiotherapy, and antivascular endothelial growth factor injections, but all have had limited or varied success. Although there have been recent advances in knowledge and technique, the management of glaucoma is extremely complex, given the high surgical risks for complications and a poor response rate to medical therapy. Further studies are critical to maximize our knowledge of this difficult disease.

New vascular classification of port-wine stains: improving prediction of Sturge-Weber risk

BACKGROUND

Facial port-wine stains (PWSs) are usually isolated findings; however, when associated with cerebral and ocular vascular malformations they form part of the classical triad of Sturge-Weber syndrome (SWS).

OBJECTIVES

To evaluate the associations between the phenotype of facial PWS and the diagnosis of SWS in a cohort with a high rate of SWS.

METHODS

Records were reviewed of all 192 children with a facial PWS seen in 2011-13. Adverse outcome measures were clinical (seizures, abnormal neurodevelopment, glaucoma) and radiological [abnormal magnetic resonance imaging (MRI)], modelled by multivariate logistic regression.

RESULTS

The best predictor of adverse outcomes was a PWS involving any part of the forehead, delineated at its inferior border by a line joining the outer canthus of the eye to the top of the ear, and including the upper eyelid. This involves all three divisions of the trigeminal nerve, but corresponds well to the embryonic vascular development of the face. Bilateral distribution was not an independently significant phenotypic feature. Abnormal MRI was a better predictor of all clinical adverse outcome measures than PWS distribution; however, for practical reasons guidelines based on clinical phenotype are proposed.

CONCLUSIONS

Facial PWS distribution appears to follow the embryonic vasculature of the face, rather than the trigeminal nerve. We propose that children with a PWS on any part of the 'forehead' should have an urgent ophthalmology review and a brain MRI. A prospective study has been established to test the validity of these guidelines.

Paroxysmal vascular events in Sturge-Weber syndrome: Role of aspirin

Sturge–Weber syndrome (SWS) is a rare, sporadically occurring neurocutaneous disorder with a frequency of approximately 1 per 50,000. The hallmark is an intracranial leptomeningeal vascular angioma in association with a port wine nevus, usually involving ophthalmic or maxillary distribution of trigeminal nerve. Other clinical findings associated with SWS are seizures, glaucoma, hemiparesis and mental retardation. The radiological hallmark is “Tram-line” or “Gyri-form” calcification. 25 to 56% of patients experience recurrent episodes of paroxysmal focal neurological deficits in form of transient hemiparesis, which may be due to vascular ischemia or postictal in origin. EEG helps to differentiate the exact etiology, as it is normal in former. Aspirin prophylaxis in those, due to ischemia decreases their recurrences and improves overall neurological prognosis. We report a 25-month-old child of SWS with recurrent episodes of transient hemiparesis and atypical midline location of facial vascular nevus.

Sclerotherapy: a novel bloodless approach to treat recurrent oral pyogenic granuloma associated with port-wine stain

Pyogenic granuloma (PG) is a commonly occurring nonneoplastic inflammatory lesion in the oral cavity. Recent reports have demonstrated a rare association between skin PG and port-wine stain (PWS). Various treatment modalities such as complete excision, curettage, cryotherapy, chemical and electric cauterizations, lasers, and intralesional corticosteroids have been used to treat the lesion. In this case report, we present a novel method for the treatment of recurrent PG in a woman with concurrent presentation of PWS. In this patient, sclerotherapy with sodium tetradecyl sulfate (STS) was used as a treatment modality with successful resolution of the lesion. The authors thus conclude that sclerotherapy with STS can be an effective alternative for the treatment of recurrent PG associated with PWS.

Successful pregnancy, epidural anaesthesia, labour, and delivery in a woman with Sturge-Weber syndrome and previous hemispherectomy

BACKGROUND

The outcomes of pregnancy and subsequent delivery of healthy neonates in women who have undergone previous near total hemispherectomy for Sturge-Weber syndrome (SWS) have rarely been reported.

CASE

A woman with SWS had two successful and uncomplicated pregnancies and deliveries under epidural anaesthesia after undergoing a near total hemispherectomy with subsequent unilateral cerebral palsy. Non-contrast MRI of the brain revealed post hemispherectomy changes with no residual meningeal angiomatosis.

CONCLUSION

As more women who undergo surgical resection for underlying SWS grow into the child-bearing years, additional reports of pregnancy and delivery outcomes in this patient population can be expected and will be valuable.

Sturge-Weber syndrome: clinical spectrum, disease course, and outcome of 30 patients

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.

A clinician's dilemma: Sturge-Weber syndrome 'without facial nevus'!!

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

Neonatal status epilepticus controlled with levetiracetam at Sturge Weber syndrome

Sturge-Weber syndrome is a rare, sporadic, congenital neurocutaneous syndrome characterized by facial cutaneous vascular malformation, leptomeningeal angioma and eye abnormalities. Seizures develop during the first year of life, may become refractory to multiple anticonvulsants and status epilepticus may develop. A rare subtype of Sturge-Weber syndrome with bilateral facial vascular malformation, unilateral cerebral involvement and neonatal status epilepticus is reported here. Neonatal status epilepticus was successfully controlled with intravenous levetiracetam infusion.

Cutaneous vascular anomalies in the neonatal period

Vascular birthmarks can be difficult to diagnose in the perinatal period due to varied growth characteristics and similar initial appearances. Location and type of birthmark can provide signals that extracutaneous involvement may be a concern. This article provides a baseline framework that can help diagnose, define associations and guide workup and treatment in these neonates.

Cutaneous findings in children with intellectual disabilities

The link between pediatric dermatology and intellectual disabilities (ID) is revised, according to the author's personal experience and the existing published work. Cutaneous manifestations in children with ID can be: (i) a key element to reach a diagnosis, as in neurodermatoses; (ii) a peculiar sign to define a complex syndrome; (iii) linked to behavioral features; (iv) iatrogenic, caused by drugs, as a side-effect; and (v) independent from ID.

Sturge-weber syndrome

Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome, characterized by the association of facial port-wine hemangiomas in the trigeminal nerve distribution area, with vascular malformation(s) of the brain (leptomeningeal angioma) with or without glaucoma. Herein, we reported Sturge-Weber syndrome in a 50-year-old man, who presented port-wine hemangiomas and epilepsy. In this case, the patient's epilepsy episodes from his first year of life had been ignored and separated from the entity of SWS by his physicians, which led to delayed treatment. This case illustrates the importance of careful examination of patients of any age with hemangiomas in the trigeminal nerve with concomitant episodes of epilepsy. In such cases, there should be yearly neuroimaging screenings to guaranteed early interdisciplinary interventions from the time of definite diagnosis.

Behavioral manifestations of sturge-weber syndrome: a case report

Sturge-Weber syndrome is a neurocutaneous syndrome that manifests with vascular malformations involving the brain, eye, and skin. We report the case of an elderly patient suffering from Sturge-Weber syndrome who presented with episodic "angry" slapping symptoms to a psychiatric facility. A detailed history, physical and mental-state examination, and elaborate neuropsychological, neuroimaging, and laboratory assessment were undertaken. Clinically, the "angry" slapping episodes were diagnosed as complex partial seizures that improved in frequency with an increase in the dose of the antiepileptic medication. We also have attempted to identify the pathophysiology of such behavioral episodes in Sturge-Weber syndrome. This case report underlines the need for detailed laboratory and neuroimaging work-up in the elderly presenting with atypical symptoms. It also emphasizes the need for identification of and differentiation between similar atypical presentations and appropriate management of resources by the medical staff.

Prevalence of oral abnormalities in a Turkish newborn population

OBJECTIVE

There are a few studies that describe the oral findings in newborn children in various populations but none conducted for a Turkish population. Hence, this study determined the prevalence of intraoral findings in a group of newborns and examined the correlation among these findings with the mother's systemic and gestational medical complications, cigarette consumption during pregnancy and consanguinity between the parents.

METHODS

2,021 full-term, newborn children were examined. Oral cysts, ankyloglossia, attached upper midline frenum and other medical diagnoses at birth were investigated. Medical information for each child and parent was recorded via standard questionnaire. Obtained data was analysed using the Pearson Chi-Square test (P≤0.05).

RESULTS

  The most common findings were of oral inclusion cysts situated palatally.

CONCLUSIONS

There was a statistically significant relationship between the presence of oral inclusion cysts with the congenital diabetes and also insulin treatment and cigarette consumption during pregnancy. Moreover, a significant relationship was found between the presence of oral inclusion cysts and gestational diabetes and with the presence of consanguinity between the parents (P=0.004).

TEMA: avaliação fonoaudiológica em síndrome de rara ocorrência. PROCEDIMENTOS: descrever o desempenho apresentado na avaliação fonoaudiológica clínica de uma paciente com diagnóstico genético de Síndrome de Sturge-Weber. Para isso, utilizou-se de avaliação da motricidade e funções orofaciais, das habilidades pragmática e semântica da linguagem oral, processos perceptuais visual e auditivo, funções cognitivas e aplicação do Denver II. RESULTADOS: na avaliação da motricidade orofacial a paciente apresentou anomalias de estruturas ósseas da face, inadequação quanto à morfologia, mobilidade e tônus de todos os órgãos fonoarticulatórios, presença de reflexos de procura e sucção primitivos. Na avaliação das habilidades pragmática e semântica da linguagem oral, processos perceptuais visual e auditivo, funções cognitivas, a paciente apresentou exploração sensoriomotora, com pouca interação e atenção compartilhada e dificuldade de contato de olhos; comunicação predominantemente gestual, não havendo registros de atos comunicativos verbais. Apresentou funções comunicativas de pedido de ação, exclamativa, exploratória e protesto, e grande uso de função não focalizada. A compreensão oral mostrou-se alterada, gestos representativos esporádicos, processos perceptuais funcionais e lateralidade indefinida. No Denver II, falhou nas áreas pessoal-social, linguagem, motor fino e grosseiro. CONCLUSÃO: a paciente apresentou diagnóstico fonoaudiológico de Distúrbio de Linguagem e Disfagia Neurogênica Orofaríngea moderada sendo necessária intervenção fonoaudiológica a fim de maximizar a comunicação, bem como adequar as estruturas e funções motoras orofaciais.

Congenital vascular malformations of the retina and choroid

PURPOSE

To review recent advances in the diagnosis and treatment of congenital vascular malformations of the retina and choroid.

METHODS

Review of the current literature on retinal haemangioblastoma, racemose haemangiomatosis, retinal cavernous haemangioblastoma, circumscribed choroidal haemangioma, and diffuse choroidal haemangioma.

CONCLUSION

The management of patients with congenital vascular lesions of the retina and choroid is advancing rapidly through recent developments in genetic testing, ocular imaging, and treatment. Most are associated with systemic disease, which may be life-threatening. New therapeutic methods such as Verteporfin photodynamic therapy and anti-angiogenic therapy have significantly improved the treatment of retinal and choroidal angiomas and vascular malformations. Ophthalmologists have a major role in detecting and diagnosing these tumours and in providing long-term care in collaboration with a specialist in the field.

Sturge-Weber syndrome: soft-tissue and skeletal overgrowth

Sturge-Weber syndrome (SWS) is characterized by capillary malformation, glaucoma, leptomeningeal vascular anomalies, and variable facial overgrowth. The purpose of this study was to document the prevalence and morbidity of facial hypertrophy in 2 cohorts: group 1, surveyed patients registered in the SWS Foundation, and group 2, patients treated at our Vascular Anomalies Center. Predictive variables included age, sex, region of capillary stain, and ocular or cerebral involvement. Outcome variables were soft-tissue and bony overgrowth, as well as the type of operative correction. In group 1, the response rate to our questionnaire was 29.3% (108/368). Facial overgrowth was documented in 60.0% of patients. Soft-tissue hypertrophy was present in 55.0%; the lip (81.0%) was the most commonly affected site. Skeletal hypertrophy was reported in 22% of patients; the maxilla (83.0%) was the most frequently overgrown bone. Overall, 23.0% of patients (36.5% with overgrowth) had an operation: 34.0% of patients with soft tissue hypertrophy and 9.0% with skeletal enlargement. In group 2, 47 patients with SWS were treated at our center: 83% had facial overgrowth, either a localized cutaneous lesion (18.0%), soft-tissue enlargement (70.0%), or bony hypertrophy (45.0%). As in group 1, the lip (75.0%) and maxilla (94.0%) were the most commonly enlarged structures. Operations were necessary for localized cutaneous lesions (86.0%), soft-tissue hypertrophy (53.0%), or skeletal overgrowth (11.0%). In conclusion, facial hypertrophy is a major component of SWS; these patients should be counseled about the risk of overgrowth and about the types of possible operative correction.

Hypomelanosis of Ito and Sturge-Weber syndrome without facial nevus: an association or a new syndrome?

Sturge-Weber syndrome without facial nevus is rare. Twenty-four cases were previously reported. Although hypomelanosis of Ito is a relatively common disorder, there was only one previous case in association with Sturge-Weber syndrome. We describe an 11-year-old boy with Sturge-Weber syndrome without facial nevus, coexistent with hypomelanosis of Ito.

Infantile spasms in the setting of Sturge-Weber syndrome

INTRODUCTION

The prevalence and outcome of the most frequent type of epilepsy in infancy-infantile spasms (IS)-are well characterized in the setting of most neurocutaneous disorders. By contrast, still there is no study describing the natural history of IS in the setting of Sturge-Weber syndrome (SWS).

MATERIALS AND METHODS

Two patients with SWS and IS were identified in our series and five in the literature. The aim of study is to evaluate the clinical, electroencephalographic (EEG) and imaging features of our cases and to compare our cases with those described in the literature. IS in the setting of SWS is an uncommon but possible event (2/19 patients seen over 13 years in our institutions).

RESULTS

We confirmed the correlation between IS and severity of SWS cutaneous and neural (extension of leptomeningeal capillary malformation) phenotype. IS in SWS seems to be atypical both from a clinical viewpoint (they are asymmetric) and from a laboratory viewpoint (EEG is not classically hypsarrhythmic).

A spectrum of unusual neuroimaging findings in patients with suspected Sturge-Weber syndrome

BACKGROUND AND PURPOSE

Sturge-Weber syndrome (SWS) is frequently associated with neurologic complications such as seizures, so diagnosing this condition has important implications for patient management. The purpose of this study was to report unusual neuroimaging findings in patients with facial port-wine stain (PWS) and clinically suspected SWS.

MATERIALS AND METHODS

Cranial MR imaging was reviewed for all children with facial port-wine stain (PWS) involving the upper face and eyelids who were referred to Great Ormond Street Hospital between 2003 and 2007 for investigation of suspected SWS. Patients were excluded from further analysis if the imaging findings were normal on initial and subsequent scans and the subject remained free of neurologic disease, or if the imaging showed the well-recognized pattern of exclusively supratentorial pial enhancement representing the pial angioma of SWS. For the remaining patients, the neurologic, dermatologic, and ophthalmologic records were examined and all available imaging was reviewed by a neuroradiologist. We documented the presence and distribution of pial enhancement; corroborative features of SWS, such as atrophy, calcification, choroid plexus changes, and ocular abnormalities; and all other intracranial abnormalities.

RESULTS

Of the 62 patients referred for assessment, imaging findings were considered typical of SWS in 32 (52%) and were normal or showed abnormalities attributable to an unrelated pathology in 20 (32%). Of the remaining 10 patients, in 7 (11%), there was evidence of a pial angioma in an unusual distribution involving infratentorial structures, with the angioma in 1 patient being diagnosed at postmortem only; in 2 (3%), there were imaging abnormalities with some features in common with typical SWS, such as subcortical calcification, but with no evidence of pial enhancement; in 1 (1.6%), the initial MR imaging finding was normal, but repeat imaging subsequently revealed pial enhancement.

CONCLUSIONS

Involvement of infratentorial structures is common but may be relatively subtle and should be actively sought. Cases in which there are certain patterns of imaging abnormalities but an apparent absence of supratentorial pial enhancement on MR imaging may represent formes frustes of SWS; visualization of pial angiomatosis may also be delayed until later in childhood than expected.
