New Onset of Seizures Leading to the Delayed Diagnosis of Sturge-Weber Syndrome in Adulthood: A Case Report

Sturge-Weber syndrome (SWS), also called encephalotrigeminal angiomatosis, is a congenital neurocutaneous disorder. It is characterized by facial and leptomeningeal angiomas as well as neurologic symptoms such as seizures and learning disabilities. We report a case of a 31-year-old male patient who presented with a history consistent with focal seizures. He was found to have a cutaneous angioma (port-wine stain) in the left temporoparietal region. CT brain revealed characteristic curvilinear calcification in the left tempoparietal cortex. The lack of tonic-clonic seizures and the pattern of his port-wine stain may have possibly delayed the diagnosis well into adulthood.
