Abstract：
BACKGROUND: Pulmonary artery (PA) aneurysms are usually diagnosed radiographically and present as small or large lesions resembling inflammation or a neoplasm on chest radiography. It has rarely been reported as an endobronchial mass.
METHODS: We report the case of a 64-year-old man who presented with recurrent hemoptysis. Bronchoscopy revealed a tumorous protrusion blocking the right middle lobe bronchus, which was confirmed to be a PA aneurysm using endobronchial ultrasound bronchoscopy and computed tomography angiography.
CONCLUSIONS: Although endobronchial PA aneurysms are rare, bronchoscopists need to add this lesion to the list of endobronchial masses for which a biopsy is to be assiduously avoided.

摘要：
背景：肺动脉（PA）动脉瘤通常通过影像学诊断，并在胸片上表现为类似炎症或肿瘤的小或大病变。它很少被报道为支气管内肿块。
方法：我们报告了一例64岁男性患者反复咯血的病例。支气管镜检查显示肿瘤突出物阻塞右中叶支气管，经支气管内超声支气管镜和计算机断层扫描血管造影证实为PA动脉瘤。
结论：尽管支气管内PA动脉瘤很少见，支气管镜检查医师需要将该病变添加到支气管内肿块列表中，以避免进行活检。
