Answer

Answer

Few cases of vasculitis of various types (giant cell arteritis, rheumatoid vasculitis, primary angiitis of the central nervous system [CNS]) associated with CAA have been reported. No consensus exists as to whether the pathologic abnormalities are related causally or whether the appearance of vasculitis is a reaction to CAA-induced angiopathic changes.
