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.
在没有血管外科手术史的患者中，感染性主动脉炎是一种非常罕见但危及生命的疾病，临床表现不具特异性，会使患者面临无法控制的败血症以及腹膜后破裂的风险。采用对比增强多排螺旋计算机断层扫描和磁共振成像的先进横断面成像技术，能够在感染性患者发生动脉瘤样扩张之前的早期阶段，对未被怀疑的主动脉炎进行可靠的诊断和特征描述。主动脉周围炎性组织的不对称分布有助于将这种特殊疾病与其他主动脉周围异常情况（如腹膜后纤维化或淋巴瘤）区分开来。
