Sturge-Weber syndrome is a rare, neurological disorder that is present at birth.
This congenital condition is primarily characterized by a distinctive port-wine stain birthmark. This birthmark typically appears on the forehead and upper eyelid, exclusively on one side of the face. As a neurological disorder, it involves the brain and can have implications beyond the visible skin mark, though its defining visual characteristic is the unilateral facial port-wine stain.
Recognizing this unique birthmark is key to identifying the syndrome, which affects the nervous system from birth.
