A 2-year-old boy presents to the nurse practitioner with new onset seizures and a history of a port-wine stain at birth. Which of the following is not a clinical feature of Sturge-Weber syndrome (SWS)?

Choice A reason: SWS is indeed a rare neurocutaneous disorder affecting the skin (port-wine stains) and central nervous system, making this a true clinical feature. Choice B reason: Neurologic manifestations, including seizures, hemiparesis, and intellectual disability, are characteristic features of SWS. Choice C reason: Management often involves anticonvulsants, glaucoma treatment, and sometimes low-dose aspirin to reduce vascular complications, confirming these are accurate features. Choice D reason: The prognosis of SWS varies widely; many patients live well into adulthood, making the statement of an average lifespan of 30 years inaccurate.
