Cerebral vasculitis or central nervous system vasculitis (sometimes the word angiitis is used instead of "vasculitis") is vasculitis (inflammation of the blood vessel wall) involving the brain and occasionally the spinal cord. It affects all of the vessels: very small blood vessels (capillaries), medium-size blood vessels (arterioles and venules), or large blood vessels (arteries and veins). If blood flow in a vessel with vasculitis is reduced or stopped, the parts of the body that receive blood from that vessel begins to die. It may produce a wide range of neurological symptoms, such as headache, skin rashes, feeling very tired, joint pains, difficulty moving or coordinating part of the body, changes in sensation, and alterations in perception, thought or behavior, as well as the phenomena of a mass lesion in the brain leading to coma and herniation. Some of its signs and symptoms may resemble multiple sclerosis. 10% have associated bleeding in the brain. ==Causes== "Primary" Central Nervous System (CNS) vasculitis is said to be present if there is no underlying cause. However, the immune system is known to play a part in the cause of the disease. This is because sometimes the immune system becomes over reactive and attacks the host's body. There are often antigens (medicines or illness that cause an allergic reaction) that are factors that help lead to this disease. Some of these possible antigens are infections, other forms of systemic vasculitis such as granulomatosis with polyangiitis or polyarteritis nodosa, connective tissue diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis, particular medications and drugs (amphetamine, cocaine and heroin), certain forms of cancer (particularly lymphomas, leukemia and lung cancer) and Behçet's disease. It may imitate, and is in turn imitated by, a number of other diseases that affect the blood vessels of the brain diffusely such as fibromuscular dysplasia and thrombotic thrombocytopenic purpura.〔
