title: [Sturge-Weber syndrome].
abstract: Facial port-wine stains are capillary malformations, which can reveal, very rarely, Sturge-Weber syndrome (SWS). SWS is a severe neurocutaneous syndrome, which involves a facial port-wine stain reaching the first branch of trigeminal nerve (V1), ophthalmologic abnormalities (especially congenital glaucoma) and neurologic signs (seizure, mental retardation, hemiparesis). Neuroimaging (CT-scan/angio-magnetic resonance imaging [MRI]) provides the diagnosis of SWS, when it shows ipsilateral leptomeningeal angioma; the best age to perform the exam is not established. Extension to superior eyelid, to other territories of trigeminal nerve (V2, V3) or to the contralateral hemiface is statistically associated to SWS. When a new-born has a facial port-wine stain reaching V1, ophthalmologic examination must be performed in the first months of life, as well as neuroimaging (at the age of 6-12 months, earlier in case of neurologic signs); a treatment of the port-wine stain by pulsed dye laser must also be considered.
