Background: Childhood primary angiitis of the central nervous system (cPACNS) is an increasingly recognized inflammatory brain disease in children.
Case presentation: We 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.
Conclusions: Recognition 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.
Keywords: CNS vasculitis; Primary angiitis of the central cervous system; cPACNS.
