Hypothalamic-pituitary dysfunction in Sturge-Weber syndrome: case report and review of the literature.

OBJECTIVES: 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. CASE PRESENTATION: 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. CONCLUSIONS: This case emphasizes the importance of endocrine evaluation and treatment of hormonal deficiencies in patients with SWS despite the absence of radiographic findings.

Consensus Statement for the Management and Treatment of Port-Wine Birthmarks in Sturge-Weber Syndrome.

Importance: Sturge-Weber syndrome (SWS) is a neurocutaneous syndrome involving the skin, brain, and eyes. Consensus recommendations for management are lacking. Objective: To consolidate the current literature with expert opinion to make recommendations that will guide treatment and referral for patients with port-wine birthmarks (PWBs). Evidence Review: In this consensus statement, 12 nationally peer-recognized experts in dermatology with experience treating patients with SWS were assembled. Key topics and questions were formulated for each group and included risk stratification, optimum treatment strategies, and recommendations regarding light-based therapies. A systematic PubMed search was performed of English-language articles published between December 1, 2008, and December 1, 2018, as well as other pertinent studies identified by the expert panel. Clinical practice guidelines were recommended. Findings: Treatment of PWBs is indicated to minimize the psychosocial impact and diminish nodularity and potentially tissue hypertrophy. Better outcomes may be attained if treatments are started at an earlier age. In the US, pulsed dye laser is the standard for all PWBs regardless of the lesion size, location, or color. When performed by experienced physicians, laser treatment can be safe for patients of all ages. The choice of using general anesthesia in young patients is a complex decision that must be considered on a case-by-case basis. Conclusions and Relevance: These recommendations are intended to help guide clinical practice and decision-making for patients with SWS and those with isolated PWBs and may improve patient outcomes.

Phakomatosis Pigmentovascularis Associated With Sturge-Weber Syndrome, Ota Nevus, and Congenital Glaucoma.

Phakomatosis pigmentovascularis (PPV) is a rare congenital malformation syndrome that is characterized by a combination of capillary abnormalities and dermal melanocytosis.We describe 3 cases of PPV combined with bilateral Sturge-Weber syndrome (SWS), Ota nevus, and congenital glaucoma.Case 1 was a 2-year-old boy. Facial port-wine stains distributed along the 3 branches of his trigeminal nerves, which suggested the existence of SWS. Gray-blue patches were spread over the frontal and temporal areas of bilateral face, waist, buttocks, and thigh. Bilateral triangular alopecia was found on the temporal scalp. The diagnosis of Ota nevus was made by the bilateral scleral malanocystosis. Increased intraocular pressure, enlarged cornea, and pathologic optic disc cupping supported the diagnoses of infantile bilateral glaucoma. Case 2 was a 4-year-old boy. Port-wine stains were found on the face along the 3 branches of the trigeminal nerve and distributed along the trunk, arms, and legs. Mongolian spots spread over his frontal and temporal areas of the bilateral face, waist, buttocks, thigh, abdomen, and back. Infantile glaucoma was found in both eyes. Ota nevus were found in the both eyes. Optic coherent tomography (OCT) scans revealed increased thickness of choroid. Case 3 was a 5-year-old boy. Besides Ota nevus and infantile glaucoma in both eyes, color Doppler ultrasonography showed choroidal hemagioma. OCT scan showed increased choroidal thickness. The bilateral triangular alopecia on the child's temporal scalp was similar to that of Case 1. Cases 1 and 2 presented with port-wine stain patches that were consistent with the characteristic manifestation of PPV type IIb. However, the CMTC of Case 3 met the diagnostic criteria for PPV type Vb.Case 1 was treated with trabeculotomies in both eyes. For Cases 2 and 3, surgical interventions were not considered due to the high risks of antiglaucomatous operation complications. We prescribed them antiglaucoma indications.The simultaneously coexistence of PPV with SWS, Ota nevus, and congenital glaucoma is rare. In the clinic, additional detailed examinations and tests of PPV patients to exclude other ocular abnormalities or extraocular involvements are necessary.

Sturge-Weber syndrome with spontaneous intracerebral hemorrhage in childhood.

A girl aged 2 years 10 months suddenly went into a deep coma and demonstrated left hemiplegia. At birth, she had exhibited a left-sided facial port-wine stain typical of Sturge-Weber syndrome (SWS) and involving the V1 and V2 distributions of the trigeminal nerve. Computed tomography showed a right thalamic hemorrhage with acute hydrocephalus. Magnetic resonance imaging with Gd enhancement 8 months before the hemorrhage had shown a patent superior sagittal sinus (SSS) and deep venous system. Magnetic resonance imaging and MR angiography studies 2 months before the hemorrhage had revealed obstruction of the SSS and right internal cerebral vein (ICV). Given that a digital subtraction angiography study obtained after the hemorrhage did not show the SSS or right ICV, the authors assumed that impaired drainage was present in the deep venous system at that stage. The authors speculated that the patient's venous drainage pattern underwent compensatory changes because of the occluded SSS and deep venous collectors, shifting outflow through other cortical venous channels to nonoccluded dural sinuses. Sudden congestion (nearly total to total obstruction) of the ICV may have caused the thalamic hemorrhage in this case, which is the first reported instance of pediatric SWS with intracerebral hemorrhage and no other vascular lesion. Findings suggested that the appearance of major venous sinus occlusion in a child with SWS could be a warning sign of hemorrhage.

The role of the thalamus in neuro-cognitive dysfunction in early unilateral hemispheric injury: a multimodality imaging study of children with Sturge-Weber syndrome.

BACKGROUND: Sturge-Weber syndrome (SWS) with unilateral hemispheric involvement is a clinical model of early onset, chronic, often progressive hemispheric injury, resulting in variable neuro-cognitive impairment. AIMS: To evaluate if abnormal diffusion and metabolism of the thalamus, a central relay station with extensive cortical connections, may serve as a simple imaging marker of neuro-cognitive dysfunction in SWS. METHODS: We obtained both diffusion tensor imaging and FDG PET in 20 children (11 girls; age range: 3-12.4 years) with unilateral SWS. Diffusion parameters as well as FDG uptake were measured in thalami, compared to normal control values, and correlated with the extent of cortical hypometabolism, deep venous abnormalities and cognitive (IQ) as well as fine motor functions. RESULTS: Children with SWS had significantly higher thalamic glucose metabolic asymmetry than controls (p=0.001). Thalamic metabolic asymmetries correlated positively with the asymmetry of thalamic diffusivity (p=0.001) and also with the extent of cortical hypometabolism (p<0.001). Severe thalamic asymmetries of glucose metabolism and diffusion were strong predictors of low IQ (metabolism: p=0.002; diffusivity: p=0.01), even after controlling for age and extent of cortical glucose hypometabolism in children with left hemispheric involvement. Ipsilateral thalamic glucose hypometabolism was also associated with impairment of fine motor functions (p=0.002). CONCLUSIONS: Both diffusion and glucose metabolic abnormalities of the thalamus are closely related to cognitive functions, independent of age and cortical metabolic abnormalities, in children with unilateral SWS. Thalamic metabolic asymmetry is a robust but simple imaging marker of neuro-cognitive outcome in children with early unilateral hemispheric injury caused by Sturge-Weber syndrome.

Ciliochoroidal effusion induced by topical latanoprost in a patient with sturge-weber syndrome.

BACKGROUND: To report drug-induced ciliochoroidal effusion in a patient with Sturge-Weber syndrome. CASE: A 17-year-old man presented with unilateral glaucoma associated with Sturge-Weber syndrome. OBSERVATIONS: His corrected visual acuity was RE 20/20 and LE 40/60. Intraocular pressure readings by Goldmann applanation tonometry were RE 32 mm Hg and LE 12 mm Hg. Fundus examination showed marked glaucomatous disc cupping in his right eye and normal finding in his left. The patient had a port-wine stain on his right upper eyelid ipsilateral to the glaucomatous eye. Antiglaucomatous medications were begun, including topical latanoprost, with a diagnosis of juvenile onset glaucoma associated with Sturge-Weber syndrome. Ultrasound biomicroscopy showed a 360 degrees circumference ciliochoroidal effusion. Forty days after starting medication, latanoprost treatment was discontinued. Ten days later, ultrasound biomicroscopy showed a total disappearance of the ciliochoroidal effusion. CONCLUSION: Interaction of the enhanced uveoscleral outflow with latanoprost in conjunction with elevated episcleral venous pressure may have caused the congestion of the aqueous humor in the supraciliary-choroidal space, resulting in the ciliochoroidal effusion.

Calcificaciones cerebrales en la enfermedad celíaca. Diagnóstico diferencial con el síndrome de Sturge-Weber atípico / Intracranial calcifications in celiac disease: inclusion of atypical Sturge-Weber syndrome in the differential diagnosis

En la última década se ha descrito la asociación entre enfermedad celíaca, epilepsia y calcificaciones cerebrales. La morfología y localización de estas calcificaciones son similares a las observadas en el síndrome de Sturge-Weber, por lo que muchos pacientes epilépticos con enfermedad celíaca silente han sido diagnosticados de síndrome de Sturge-Weber atípico. Presentamos un caso de enfermedad celíaca en un varón de 35 años de edad que mostró calcificaciones cerebrales, haciendo hincapié en los signos radiológicos que ayudan al diagnóstico diferencial con el síndrome de Sturge-Weber atípico. La instauración temprana del tratamiento adecuado (dieta sin gluten), mejora en muchos casos el cuadro clínico epiléptico, lo que da mayor relevancia al diagnóstico (AU)

Anterior chamber angle vascularization in Sturge-Weber syndrome. Report of a case.

The case of a 20-year-old woman with a left-sided facial hemangioma and a homolateral glaucoma is reported, complete with the histology of a trabeculectomy specimen. Her left eye had an episcleral hemangioma and goniodysgenetic features in the anterior chamber angle, while the intraocular pressure was measured to be 45 mmHg. The left optic disc showed a large cupping and the left visual field was constricted. The right eye had no glaucomatous changes. Histological examination of the trabeculectomy specimen by both light and electron microscopy showed multiple congenital anomalies. There was a cluster of blood vessels in the trabecular meshwork. Abnormal accumulations of fine granular extracellular matrixes were observed in both the juxtacanalicular connective tissue and around the vascular structures. The lumen of Schlemm's canal was subdivided into three or four parts with few giant vacuole structures. The endothelial cells lining the inner wall of Schlemm's canal contained a well-formed basal lamina with many villi projecting into the lumen. These findings suggest that the multiple anomalies observed in the trabecular tissue may contribute to the manifestation of glaucoma in Sturge-Weber syndrome.

[A case report of Weber's syndrome associated with supranuclear vertical gaze palsy caused by the ipsilateral thalamomesencephalic lesion].

We report a rare case showing Weber's syndrome associated with supranuclear vertical gaze palsy caused by the ipsilateral lesion of the rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF), which is regarded as the supranuclear control center of vertical gaze. To date, no literature concerning Weber's syndrome associated with the ipsilateral riMLF lesion was documented. The patient was a 53-year-old female, who suddenly developed unconsciousness and left-sided weakness. Neurological findings on admission revealed right third nerve palsy, severe supranuclear vertical gaze palsy, almost complete convergence palsy, left hemiparesis and hyperreflexia with positive Babinski's sign on the left side. There was no sign of pupillary disturbance or no abnormality of the horizontal movements of the left eye. The vestibulo-ocular reflex of the left eye was preserved. There was no sensory disturbance. Cranial MRI had the advantages in demonstrating unilateral ischemic lesions at the cerebral peduncle and the thalamomesencephalic junction involving the unilateral riMLF on the right side. Recent reports have demonstrated that supranuclear vertical gaze palsy is caused by the unilateral riMLF lesion. We confirm that the unilateral riMLF lesion causes supranuclear vertical gaze palsy in our case and that cranial MRI has the advantages in demonstrating the specific lesion.

Peripheral iridectomy with scleral cautery for glaucoma.

Peripheral iridectomy with cautery (Scheie operation) was carried out on 113 eyes with glaucoma. The results were so favorable and the complications so few that we believe this operation still has an important place in the surgical management of the glaucomas and is noteworthy in the light of the trend to more precise surgery of the canal of Schlemm and the trabeculae.
