Abstract
Immunoglobulin G4-related disease (IgG4)-related disease is a newly recognized form of immune-mediated disease, which is characterized by IgG4+ lymphoplasmacytic infiltration and fibrosis in the systemic organs. Although aortitis/periaortitis is a phenotype of IgG4-related disease, the relationship between cerebrovascular disease and IgG4-related disease remains unclear. Herein, we report the case of a 49-year-old man with recurrent stroke induced by IgG4-related arteritis. Case reports or studies examining the association between IgG4-related arteritis and stroke are limited. Although a definitive link between IgG4-related arteritis and stroke has not been established, IgG4-related arteritis should be considered as an etiology in patients with recurrent idiopathic stroke.
