PURPOSE: Inflammatory stenoses of cerebral arteries cause stroke in patients with florid vasculitis. However, diagnosis is often difficult even with digital subtraction angiography (DSA) and biopsy. The purpose of this study was to establish the value of contrast-enhanced MRI, proven to be sensitive to extradural arteritis, for the identification of intracranial vessel wall inflammation. PATIENTS AND METHODS: Twenty-seven patients with a diagnosis of cerebral vasculitis affecting large brain...Expand abstract
