title: Cerebral granulomatous angiitis with atypical features.
abstract: A case of cerebral granulomatous angiitis of the left temporal lobe mimicking a brain tumour is presented. Following surgical removal of a glioma-imitating mass, histological examination disclosed a granulomatous vasculitis. Treatment consisted of dexamethasone given in tapering doses for 5 days after surgery. Clinical and morphological differences from other reported cases of granulomatous angiitis of the nervous system are described.
