<unk>  is the inflammation of the aortic wall.  The disorder is rare, but potentially life-threatening.<unk>  may occur at any age.<unk>  is classified according to the cause into 2 groups: inflammatory and infectious.  Life threatening causes of<unk>  include bacteremia and mycotic aneurysm.  Common causes of<unk>  include ankylosing spondylitis, giant cell arteritis, Takayasu arteritis, and syphilis.<unk>  must be differentiated from aortic dissection, intramural hematoma, and penetrating atherosclerotic ulcer. If left untreated, infectious<unk>  is associated with a high rate of aortic rupture and subsequent mortality.<unk>  due to either giant cell arteritis or Takayasu arteritis has a high rate of recurrence despite therapy. Common complications of<unk>  include: aortic aneurysm, aortic rupture, aortic dissection, thrombus formation in the aortic lumen, and hypertension.  The prognosis of infectious<unk>  is generally poor.  Prognosis of isolated<unk>  and<unk>  associated with rheumatic diseases is generally good with prompt diagnosis. Symptoms of<unk>  include back pain, fever, abdominal pain, chest pain, shortness of breath, and fatigue. Common physical examination findings of<unk>  include abnormal heart sounds, hypertension or hypotension, a difference in blood pressure between both arms, and either reduced or absent pulses. CT scan with the administration of iodinated contrast (CTA) may be diagnostic of<unk> .  Magnetic resonance angiography (MRA) is the noninvasive imaging of choice for<unk> .  On transthoracic and transesophageal echocardiogram,<unk>  is characterized by aortic wall thickening. Early antimicrobial therapy with broad spectrum coverage is indicated in infectious<unk> .  The preferred agents include either Cefotaxime, Ciprofloxacin, penicillinase-resistant penicillins, or Vancomycin. Surgical debridement is recommended among patients with gram-negative rod<unk> .
