Vasculitis - Causes

Vasculitis occurs when your immune system injures your blood vessels by mistake. What causes this to happen is not fully known, but when it occurs, your blood vessels become inflamed and can narrow or close off. Rarely, the blood vessel wall may weaken, causing it to expand or bulge. This bulge is known as an aneurysm.
