Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1] Associate Editor(s)-in-Chief: Maliha Shakil, M.D. [2]

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.^[1]

Computed Tomography

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

Thickening of the aortic wall
Periaortic inflammation

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	Mural thickening Frank aneurysm Long segment thickening with smooth distal tapering, commonly found in the descending aorta and subclavian arteries Annuloaortic ectasia Ascending aortic dilation
Takayasu arteritis	A “double ring” appearance, due to a brightly enhanced outer ring of inflamed media and adventitia surrounding poorly enhanced edematous intima
