title: Early non-aneurysmal infectious aortitis: Cross-sectional imaging diagnosis.
abstract: In patients without history of vascular surgery, infectious aortitis is a very uncommon, life-threatening condition with nonspecific clinical manifestations, which exposes the patient to uncontrolled sepsis and to the risk of retroperitoneal rupture. State-of-the-art cross-sectional imaging with contrast-enhanced multidetector computed tomography and magnetic resonance imaging allows confident diagnosis and characterization of unsuspected aortitis in septic patients at an early stage before the development of aneurysmal dilatation. The asymmetric distribution of periaortic inflammatory tissue is helpful for the differentiation of this exceptional disorder from other periaortic abnormalities such as retroperitoneal fibrosis or lymphoma.
