OBJECTIVE
The purpose of this pictorial essay is to illustrate the radiologic manifestations of pulmonary artery aneurysms and pseudoaneurysms with emphasis on the findings on contrast-enhanced CT.
CONCLUSION
Pulmonary artery aneurysms and pseudoaneurysms are uncommon. Most are caused by trauma, often iatrogenic, infection, and Behçet's syndrome. Less common causes include pulmonary hypertension, congenital heart disease, neoplasms, and connective tissue disease. Recognition of pulmonary artery aneurysms and pseudoaneurysms is important because of the high morbidity and mortality rates of rupture.
目的
本图文文章的目的是阐述肺动脉瘤和假性动脉瘤的放射学表现，重点是对比增强CT的表现。
结论
肺动脉瘤和假性动脉瘤并不常见。大多数由创伤引起，常为医源性、感染性和白塞病。较不常见的病因包括肺动脉高压、先天性心脏病、肿瘤和结缔组织病。由于破裂的高发病率和死亡率，认识肺动脉瘤和假性动脉瘤很重要。
