Coronary artery aneurysm (CAA) is a rare form of coronary artery disease characterized by abnormal dilation of a coronary artery segment. While CAAs can present with various symptoms, syncope is notably uncommon, with limited documented cases. We present the case of a 24-year-old woman with a 2-month history of recurrent syncope, occurring in the absence of other symptoms. Initial evaluations, including MRI and cardiac examinations, revealed no abnormalities. However, a transthoracic echocardiogram identified a ring-like structure adjacent to the tricuspid valve, and subsequent computed tomography angiography confirmed a large right coronary artery aneurysm. This case highlights the rare presentation of recurrent syncope as a manifestation of CAA, emphasizing the need for timely diagnosis and intervention in similar cases.
冠状动脉瘤（CAA）是一种罕见的冠状动脉疾病形式，其特征为冠状动脉节段异常扩张。虽然冠状动脉瘤可表现出各种症状，但晕厥明显不常见，文献记载的病例有限。我们报告一例24岁女性，有2个月反复晕厥病史，且无其他症状。包括磁共振成像（MRI）和心脏检查在内的初步评估未发现异常。然而，经胸超声心动图发现三尖瓣附近有一个环状结构，随后的计算机断层血管造影证实存在一个巨大的右冠状动脉瘤。该病例突出了反复晕厥作为冠状动脉瘤表现的罕见性，强调了对类似病例及时诊断和干预的必要性。
