What primary symptom is associated with Sturge-Weber syndrome?

Sturge-Weber syndrome is a neurocutaneous disorder that is characterized by a facial capillary malformation (port-wine stain) and neurological abnormalities due to an associated leptomeningeal angioma. One of the primary symptoms associated with this condition is seizures, which are a consequence of cortical irritation resulting from the underlying cerebral vascular malformation.

Additionally, patients may present with neurological deficits, including hemisensory or hemimotor findings, which arise from the structural abnormalities in the brain. The trigeminal port-wine stain, typically found on the forehead and upper eyelid, is also a hallmark of the syndrome and serves as a cutaneous manifestation linked with these neurological changes.

Considering these points, the presence of port-wine stains, seizures, and possible hemi neurology findings are all closely associated with Sturge-Weber syndrome. Therefore, it is accurate to state that all of these symptoms can be manifestations of the condition, making the choice that includes all of them correct.
