A brain SPECT can show decreased blood flow to the brain and brain damage. The definite diagnosis of vasculitis is established after a biopsy of involved organ or tissue, such as skin, sinuses, lung, nerve, brain, and kidney. The biopsy elucidates the pattern of blood vessel inflammation.
Cerebral 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. [1] It affects all of the vessels: very small blood vessels ( capillaries ), medium-size blood vessels ( arterioles and venules ), or large blood vessels ...
The underlying mechanism involves inflammation of the small blood vessels that supply the walls of larger arteries. [4] This mainly affects arteries around the head and neck, though some in the chest may also be affected. [4] [8] Diagnosis is suspected based on symptoms, blood tests, and medical imaging, and confirmed by biopsy of the temporal ...

More specific symptoms occur usually based off where in body the vasculitis is occurring, and which organ is supplied by that blood vessel. Reduced blood flow caused by vasculitis can cause organ ischemia which can happen in two ways. First, blood cells clump onto the exposed tissue factor and collagen on the inside of blood vessels forming ...
Temporal arteritis, mass in brain: Temporal arteritis is an inflammation of vessels close to the temples in older people, which decreases blood flow to the brain and causes pain. May also have tenderness in temples or jaw claudication. Some brain cancers are more common in older people.
The blood–brain barrier becomes more permeable, leading to "vasogenic" cerebral edema (swelling of the brain due to fluid leakage from blood vessels). Large numbers of white blood cells enter the CSF, causing inflammation of the meninges and leading to "interstitial" edema (swelling due to fluid between the cells). In addition, the walls of ...
