Pulmonary artery pseudoaneurysms (PAPs) are rare serious vascular abnormalities mostly due to infections and trauma, although other conditions such as vasculitis, neoplasms, or inflammatory lung diseases can also predispose to this entity. Endovascular techniques such as embolization or covered stent placement have mostly substituted surgical approaches, for their lower invasiveness and greater security, mainly in patients with life-threatening hemoptysis. The purpose of this manuscript is to describe the imaging findings of pulmonary artery pseudoaneurysms and their endovascular management including tips to help interventional radiologists. PAP should be diagnosed as accurately and early as possible in order to prompt endovascular management of further life-threatening hemoptysis. KEY POINTS: • Pulmonary artery pseudoaneurysms (PAPs) are rare serious vascular abnormalities that may represent a life-threatening condition, mainly due to Staphylococcus, Streptococcus, or Mycobacterium tuberculosis. • Radiologists should know the imaging findings of PAP in order to make an accurate and early diagnosis to prompt endovascular management of further life-threatening hemoptysis.
肺动脉假性动脉瘤（PAP）是一种罕见的严重血管异常，主要由感染和外伤引起，尽管其他疾病如血管炎、肿瘤或炎性肺病也可能导致这种疾病。血管内技术，如栓塞或带膜支架放置，已在很大程度上取代了手术方法，因其创伤较小且安全性更高，主要适用于有生命威胁性咯血的患者。本文旨在描述肺动脉假性动脉瘤的影像学表现及其血管内治疗，包括有助于介入放射科医生的技巧。为了及时进行可能危及生命的咯血的血管内治疗，应尽可能准确和早期诊断 PAP。主要重点：•肺动脉假性动脉瘤（PAP）是一种罕见的严重血管异常，可能是一种危及生命的情况，主要由金黄色葡萄球菌、链球菌或结核分枝杆菌引起。•放射科医生应该了解 PAP 的影像学表现，以便做出准确和早期的诊断，及时进行可能危及生命的咯血的血管内治疗。
