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 both the skin and nervous system, often presenting with facial port-wine stains and neurological symptoms. Choice B reason: Seizures, hemiparesis, and intellectual disability are well-documented features of SWS, consistent with the patient’s presentation. Choice C reason: Management of SWS can include anti-seizure medications for seizures, treatment of glaucoma, and occasionally low-dose aspirin to reduce risk of vascular complications; these are accurate clinical features. Choice D reason: The prognosis for SWS varies widely; many patients survive into adulthood with appropriate management. An average lifespan of 30 years is not accurate, making this statement not a true clinical feature of SWS.
