Sturge-Weber syndrome (encephalotrigeminal angiomatosis)
Epidemiology: rare congenital vascular disorder
Pathology:
- triad of unilateral vascular malformations (pure form)
a) capillary malformation in the distribution of the trigeminal nerve (nevus flammeus, port-wine stain)
b) vascular malformations in the choroid, often with secondary glaucoma
c) vascular malformations of the leptomeninges with superficial calcifications in the brain result often with neurologic signs
Genetics: sporadic occurence, not inheritable
Clinical manifestations:
1) unilateral occurence
2) port-wine stain* occurs in distribution of the trigeminal nerve, generally middle (maxillary nerve) & superior branches (ophthalmic nerve)
- present at birth
3) manifestations which may be present
a) contralateral hemiparesis
b) muscular hemiatrophy
c) epilepsy (seizures)
d) mental retardation
e) glaucoma
f) ocular palsy
g) mucosal involvement of mouth & conjunctiva
h) headaches
* image [6]
Special laboratory:
- tonometry: intraocular pressure may be elevated
Radiology:
1) skull films show calcified angiomas or localized linear calcifications along cerebral convolutions
2) CT neuroimaging
3) magnetic resonance imaging
- unilateral cerebral atrophy with leptomeningeal enhancement along unilateral cerebral convexity (image [6]
Differential diagnosis:
- Klippel-Trenaunay-Weber syndrome
Management:
1) treatment is symptomatic
2) laser treatment may be usefil to lighten &/or remove port wine stains
3) anticonvulsant(s) for seizures
4) surgery &/or eyedrops for glaucoma
5) prognosis: not fatal
