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

ABSTRACT:

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.

Project description:AIM:We assessed the utilization of the National Institutes of Health Quality of Life in Neurological Disorders (Neuro-QoL) in pediatric patients with Sturge-Weber syndrome, a rare neurovascular disorder which frequently results in seizures, brain atrophy, calcification, and a range of neurological impairments. METHODS:Subjects were seen clinically and consented for research. All 22 patients filled out the Pediatric Neuro-QoL. The Neuro-QoL subscores were converted to T-scores to compare with the referenced control population. Twenty-one participants also filled out the Brain Vascular Malformation Consortium Database Questionnaire containing data pertaining to Sturge-Weber syndrome-related medical history, medications, comorbidities, and family history. All data were analyzed with a significance threshold of P < 0.05. RESULTS:Cognitive function quality of life was significantly lower (P < 0.001) in pediatric patients with Sturge-Weber syndrome compared with referenced control subjects. Male gender (P = 0.02) was associated with lower cognitive function Neuro-QoL. The extent of skin (R = -0.46, P = 0.04), total eyelid port-wine birthmark (R = -0.56, P = 0.007), eye (R = -0.58, P = 0.005), and total Sturge-Weber syndrome involvement (R = -0.63, P = 0.002) were negatively correlated with cognitive function Neuro-QoL. A younger age at seizure onset was associated with lower cognitive function Neuro-QoL (hazard ratio = 0.90, P = 0.004) even after controlling for extent of brain, skin, or eye involvement. Antidepressant use was associated with lower cognitive function Neuro-QoL (P = 0.005), and cognitive function Neuro-QoL was negatively correlated with depression Neuro-QoL; however, after adjusting for depression this relationship was no longer significant. CONCLUSIONS:The results suggest targeting cognitive function Neuro-QoL in treatment trials and reiterate the prognostic value of early seizure onset. In addition, sex-related differences were noted, which should be further studied.

Project description:BackgroundEnlarged deep medullary veins (EDMVs) in patients with Sturge-Weber syndrome (SWS) may channel venous blood from the surface to the deep vein system in brain regions affected by the leptomeningeal venous malformation. Thus, the quantification of EDMV volume may provide an objective imaging marker for this vascular compensatory process. The present study proposes a novel analytical method to quantify enlarged EDMV volumes in the affected hemisphere of patients with unilateral SWS.MethodsTwenty young subjects, including 10 patients with unilateral SWS and 10 healthy siblings (age 14.5±6.7 and 16.0±7.0 years, respectively) underwent 3T brain MRI scanning using susceptibility-weighted imaging (SWI) and volumetric T1-weighted sequences. The proposed image analytic steps segmented EDMVs in white matter regions, defined on the volumetric T1-weighted images, by statistically associating the likelihood of intensity, location, and tubular shape on SWI. The volumes of the segmented EDMVs, calculated in each hemisphere, were compared between affected and unaffected hemispheres. EDMV volumes were also correlated with visually assessed EDMV scores, hemispheric white matter volumes, and cortical surface areas. Parametric tests including Pearson's correlation, unpaired and paired t-tests, were used. A P value <0.05 was considered statistically significant.ResultsIt was found that EDMVs were identified well in SWS-affected hemispheres while calcified regions were excluded. Mean EDMV volumes in the SWS-affected hemispheres were 10-12-fold greater than in the unaffected or healthy control hemispheres; while white matter volumes and cortical surface areas were lower. EDMV volumes in the SWS-affected hemispheres showed a strong positive correlation with the visual EDMV scores (r=0.88, P=0.001) and an inverse correlation with cortical surface area ratios (r=-0.65, P=0.04) but no correlation with white matter volume ratios.ConclusionsEDMVs were detected in the SWS-affected atrophic hemispheres reliably while avoiding calcified regions. The approach can be used to quantify enlarged deep cerebral veins in the human brain, which may provide a potential marker of cerebral venous remodeling.
