Acute cerebrovascular disorder induced by allergic vasculitis. A case report

A patient with vascular disease of the brain due to allergic vasculitis, which had been misdiagnosed for many years, was given anti-inflammatory, antituberculosis and antitumor drugs with no avail. He was admitted this time for an attack after eating food prepared with leftover oil used for frying hairtail. Considering the possibility of allergic vasculitis, we tried antianaphylactics and immunosuppression drugs including dexamethasone with satisfactory results. The final diagnosis was allergic granulomatous vasculitis.
