The CT appearance of mycotic abdominal aortic aneurysms leading to eventual rupture has been well described. On the other hand, ruptured nonaneurysmal bacterial aortitis has not been demonstrated in the CT literature. We present two cases with subsequent rupture documented on CT. The characteristic findings of periaortic density and adjacent gas collection should suggest the diagnosis of acute aortic infection. This may herald impending rupture, even in the absence of aneurysmal dilatation, and should direct therapy accordingly.
导致最终破裂的霉菌性腹主动脉瘤的CT表现已得到充分描述。另一方面，CT文献中尚未证实有破裂的非动脉瘤性细菌性主动脉炎。我们报告两例经CT证实随后发生破裂的病例。主动脉周围密度和邻近气体聚集的特征性表现应提示急性主动脉感染的诊断。即使在没有动脉瘤扩张的情况下，这也可能预示即将发生破裂，并应据此指导治疗。
