Primary cerebral vasculitis

Vasculitides are rare conditions affecting vessels of different type and caliber. They are characterized by inflammation of the blood vessel walls and vascular damage causing alterations in blood flow. The resulting clinical syndromes mostly result from tissue ischemia, vascular damage and inflammation affecting one or more organs or systems. Primary isolated vasculitic involvement of the central nervous system (primary CNS vasculitis) is a rare form characterized by inflammation of the blood vessels in the brain and medulla without evidence of vasculitis symptoms outside the CNS.
