침투성 동맥경화성 궤양: 종격동 확장증에서 주의할 또 다른 감별진단

초록

A widened mediastinum is not always caused by aortic dissection,which is the default diagnosis among emergency physicians. Other acute aortic syndromes should be included in differential diagnosis, such as penetrating atherosclerotic ulcer (PAU), intraluminal hematoma, aneurismal leak, and traumatic transection. When an ulcerative lesion is found in the atherosclerotic aorta, especially the descending aorta of an elderly, PAU should be considered as the possible cause of widened mediastinum. We present a case of PAU, the diagnosis of which was delayed without the knowledge of PAU even though thoracic computed tomography showed widened mediastinum and suspious pericardial effusion.
