There are approximately 20 different disorders that are classified as “vasculitis”. “Angiitis” and “Arteritis” are both synonyms for vasculitis, literally meaning “inflammation within blood vessels” or “inflammation in arteries”, respectively. Because there are so many types of vasculitis, the group is sometimes referred to in the plural: vasculitides (pronounced “vas que lit’ i deez”, with the accent on the third syllable).
There are many different types of diseases that belong to this category. Although the diseases are similar in some ways, they often differ with respect to which organs are affected, which medications are used to treat them, and other characteristics.
