Incidentally detected noninfectious thoracic aortitis: A clinical approach.

Noninfectious aortitis is occasionally detected incidentally, either on imaging or on histopathologic review after open thoracic aortic surgery. It can present as a clinically asymptomatic, seemingly focal lesion, as diffuse inflammation throughout several aortic segments but sparing the branch vessels, or as a manifestation of a widespread systemic condition. Treatment differs based on etiology, so once identified, all patients with aortitis need a thorough evaluation, laboratory tests, complete large-vessel imaging, and a referral to a vasculitis expert. All patients with aortitis are at high risk of future vascular complications and should be followed with serial clinical evaluations and imaging.
