A right-sided aortic arch with mirror-image branching is a rare vascular anomaly, often associated with congenital heart defects. However, its occurrence with a vascular ring in the absence of cardiac abnormalities is extremely rare. We report the case of a 62-year-old male presenting with acute dyspnea, in whom CT angiography revealed a right-sided aortic arch with a vascular ring formed by an aortic diverticulum and the left brachiocephalic artery, causing mild tracheal and esophageal compression. Echocardiography confirmed the absence of cardiac anomalies. This case highlights a rare presentation of a right-sided aortic arch with a vascular ring in an adult patient. While often asymptomatic, such anomalies may contribute to airway or esophageal compression, warranting careful imaging evaluation and tailored management.
镜像分支的右侧主动脉弓是一种罕见的血管异常，常与先天性心脏缺陷相关。然而，在无心脏异常的情况下出现伴有血管环的右侧主动脉弓极为罕见。我们报告一例62岁男性因急性呼吸困难就诊，CT血管造影显示右侧主动脉弓伴有由主动脉憩室和左头臂动脉形成的血管环，导致气管和食管轻度受压。超声心动图证实无心脏异常。该病例突出了成年患者中伴有血管环的右侧主动脉弓的罕见表现。虽然此类异常通常无症状，但可能导致气道或食管受压，需要进行仔细的影像学评估和个体化管理。
