When chronic aortic dissection (CAD) is associated with aortic dilatation, the risk of aortic rupture increases. We report a case of CAD complicated by acute aortitis that was depicted in contrast-enhanced magnetic resonance imaging (MRI). Contrast-enhanced MRI allows early detection of subtle changes in the aortic wall as well as disease activity. Inflammation of aortic wall in the aortic dissection can be at higher risk of the dissected aortic expansion and rupture. When we recognize inflammation of unknown origin with CAD, contrast-enhanced MRI should be performed to rule out CAD complicated by acute aortitis may lead to catastrophic complications.
当慢性主动脉夹层（CAD）合并主动脉扩张时，主动脉破裂的风险会增加。我们报告了一例经对比增强磁共振成像（MRI）显示的CAD并发急性主动脉炎的病例。对比增强MRI能够早期检测主动脉壁的细微变化以及疾病活动情况。主动脉夹层中主动脉壁的炎症会使夹层主动脉扩张和破裂的风险更高。当我们认识到CAD合并不明原因的炎症时，应进行对比增强MRI以排除CAD并发急性主动脉炎，因为这可能导致灾难性并发症。
