Right aortic arch with mirror image branching (RAMI) is a rare congenital defect of the aorta. The exact incidence of RAMI in the general population is unclear. In RAMI the first branch arising from the arch is the left innominate artery, followed by the right carotid artery and right subclavian arteries. We report a case of an adult female patient with RAMI discovered as an incidental finding during radiological investigations for suspected pulmonary embolism in emergency department. No other congenital malformations were reported. It is important to recognize congenital variants of the aortic arch, as they can have relevant implications for patients' prognosis and management. Therefore, being aware of these conditions is key to avoid any mistakes or surgical and endovascular complications.
右位主动脉弓伴镜像分支（RAMI）是一种罕见的主动脉先天性缺陷。一般人群中RAMI的确切发病率尚不清楚。在RAMI中，从主动脉弓发出的第一分支是左无名动脉，其次是右颈动脉和右锁骨下动脉。我们报告一例成年女性患者，在急诊科因疑似肺栓塞进行放射学检查时偶然发现患有RAMI。未报告其他先天性畸形。认识主动脉弓的先天性变异很重要，因为它们可能对患者的预后和治疗有相关影响。因此，了解这些情况是避免任何错误以及手术和血管内并发症的关键。
