The serious nature of false aneurysms that develop in the aortic isthmus after blunt chest trauma is well known. The authors describe the case of a 33-year-old woman who presented with symptoms of chronic post-traumatic pseudoaneurysm of the aorta 3 months after blunt chest trauma. Radiologic investigations could not substantiate an aortic disruption. A bronchogenic cyst masquerading as a false aneurysm of the aorta was identified at thoracotomy. Bronchogenic cysts are one of the most common causes of primary mid-mediastinal masses and should be considered as potential causes of mid-mediastinal enlargement. However, this consideration should not delay urgent surgery if vascular damage cannot be ruled out.
钝性胸部创伤后主动脉峡部出现的假性动脉瘤的严重性众所周知。作者描述了一名33岁女性的病例，该女性在钝性胸部创伤3个月后出现慢性创伤后主动脉假性动脉瘤的症状。影像学检查未能证实主动脉破裂。开胸手术时发现一个伪装成主动脉假性动脉瘤的支气管源性囊肿。支气管源性囊肿是原发性中纵隔肿块最常见的原因之一，应被视为中纵隔增大的潜在原因。然而，如果不能排除血管损伤，这种考虑不应延迟紧急手术。
