6 year old female child with Sturge Weber syndrome

Sturge-Weber syndrome is a neurological disorder indicated at birth by seizures accompanied by a large port-wine stain birthmark on the forehead and upper eyelid of one side of the face.  The birthmark can vary in color from light pink to deep purple and is caused by an overabundance of capillaries around the trigeminal nerve just beneath the surface of the face.

Sturge-Weber syndrome is also accompanied by the loss of nerve cells and calcification of tissue in the cerebral cortex of the brain on the same side of the body as the birthmark.

Neurological symptoms include seizures that begin in infancy and may worsen with age. Convulsions usually happen on the side of the body opposite the birthmark and vary in severity.  There may be muscle weakness on the same side.

Some children will have developmental delays and mental retardation; most will have glaucoma (increased pressure within the eye) at birth or developing later.  The increased pressure within the eye can cause the eyeball to enlarge and bulge out of its socket (buphthalmos).

Sturge-Weber syndrome rarely affects other body organs.
