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]
- Thickening of the aortic wall
- Periaortic inflammation
CT scan may be helpful in the diagnosis of aortitis due to giant cell arteritis. Findings on CT suggestive of aortitis due to giant cell arteritis include:[2]
- 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
On CTA, aortitis due to Takayasu arteritis is characterized by:
- A “double ring” appearance, due to a brightly enhanced outer ring of inflamed media and adventitia surrounding poorly enhanced edematous intima [2]
CT scan may also be helpful in the diagnosis of the complications of aortitis. Findings on CT suggestive of complications of aortitis include: [1]
- Aortic and arterial calcification
- Stenotic lesions of the aorta
- Aortic aneurysm
- Luminal thrombus
