All Diseases > Aortitis


Disease Category: Vasculitis Disorders

Aortitis is a rare form of vasculitis characterized by inflammation that predominantly affects the aorta. This type of vasculitis has been recognized as a separate entity relatively recently, and its definition continues to be the subject of debate. Generally, cases of aortitis include patients with aortitis with or without vasculitis of other large vessels who cannot be classified as having another type of large vessel vasculitis (such as giant cell arteritis or Takayasu’s arteritis) or another systemic condition known to be associated with aortitis.
