Sturge Weber syndrome

SWS is an encephalo trigeminal angiomatosis, a rare congenital neurological and skin disorder, one of the phakomatoses. Unlike other neurocutaneous disorders (phakomatoses),  Sturge-Weber occurs sporadically without hereditary aetiology.

Characterised by port-wine stains of the face and ipsilateral lepto meningeal angioma.

Port-wine stain as birthmark on the forehead light pink to deep purple in colour, caused by abundance of capillaries around the ophthalmic branch of the trigeminal nerve.

Symptomatic with seizures from birth, mental retardation, glaucoma.
