An ischemic stroke as the presenting manifestation of rapidly progressive primary angiitis of central nervous system in a 17-year-old boy

Abstract

BackgroundChildhood primary angiitis of the central nervous system (cPACNS) is an increasingly recognized inflammatory brain disease in children. Case presentationWe present a case of a 17-year-old boy with recurrent ischemic events over a short time period. Diagnosis of angiography positive cPACNS was made based on neuroimaging findings while secondary causes or mimics of CNS vasculitis were meticulously excluded. The patient exhibited rapid deterioration of his condition with poor initial response to immunosuppressive treatment. ConclusionsRecognition of cPACNS remains a challenge because of rarity of disease, unexplained etiopathogenesis, protean clinical presentation, as well as lack of specific laboratory and neuroimaging markers.
