Overview

CT scan with the administration of iodinated contrast (CTA) may be diagnostic of aortitis. Findings on CT suggestive of aortitis include thickening of the aortic wall and periaortic inflammation. CT scan may also be helpful in the diagnosis of the complications of aortitis. Findings on CT suggestive of complications of aortitis include aortic and arterial calcification, stenotic lesions of the aorta, aortic aneurysm, and luminal thrombus.[1]

Computed Tomography

CT scan with the administration of iodinated contrast (CTA) may be diagnostic of aortitis. Findings on CT suggestive of acute aortitis include:[1]

Findings on CT suggestive of aortitis due to giant cell arteritis and Takayasu arteritis include:[2]

Aortitis due to specfic disease CT scan findings
Giant cell arteritis
Takayasu arteritis
  • A “double ring” appearance, due to a brightly enhanced outer ring of inflamed media and adventitia surrounding poorly enhanced edematous intima


CT scan may also be helpful in the diagnosis of the complications of aortitis. Findings on CT suggestive of complications of aortitis include: [1]
