Serial magnetic resonance imaging in isolated angiitis of the central nervous system

Abstract
Isolated angiitis of the central nervous system (IACNS) is a rare form of vasculitis restricted to the CNS.We report serial MRI findings in a biopsy-proven case of IACNS. MRI showed extensive white matter and subcortical disease. Before specific treatment, neuroimaging showed the development of new lesions corresponding with an overall progressive clinical course of the illness; the post-treatment MRI showed improvement.
