Bronchial artery aneurysm and pseudoaneurysm is a rare but life-threatening diagnosis due to catastrophic complications from rupture. Prompt detection and management is key to prevent complications. CT angiogram and digital subtraction angiography are preferred diagnostic imaging modalities. Being very uncommon, these entities can be misdiagnosed as a nonspecific mediastinal soft tissue mass, which can lead to delay in diagnosis and inappropriate or delayed management. We present a case of 72-year-old woman with incidentally detected large bronchial artery pseudoaneurysm, incorrectly classified as mediastinal malignancy at outside facility, receiving follow-up exams for 2 years, before correct diagnosis and management.
支气管动脉动脉瘤和假性动脉瘤是一种罕见但危及生命的诊断，因为破裂会引发灾难性并发症。及时检测和处理是预防并发症的关键。CT血管造影和数字减影血管造影是首选的诊断成像方式。由于非常罕见，这些病变可能被误诊为非特异性纵隔软组织肿块，从而导致诊断延迟以及治疗不当或延误。我们报告一例72岁女性病例，其偶然发现巨大支气管动脉假性动脉瘤，在外院被错误分类为纵隔恶性肿瘤，接受了2年的随访检查，最终才得以正确诊断和处理。
