Giant coronary artery aneurysm is an extremely rare form of coronary artery disease. The most common cause of coronary artery aneurysms is atherosclerosis. Although it is usually asymptomatic, it may have various clinical presentations, including angina, myocardial infarction or sudden death.
A 32-year-old woman presented with edema of the upper and lower limbs, palpitation, and chest pain, and was diagnosed with a giant right coronary artery aneurysm that had initially mimicked a mediastinal cyst. Although computed tomography (CT) suggested a mediastinal cyst, trans-thoracic echocardiography revealed an extra pericardial cyst. The definitive diagnosis of right coronary artery aneurysm was made based on CT angiography and coronary angiography findings. As treatment, aneurysmectomy was performed, and she was discharged on the sixth postoperative day with good general health condition.
Coronary artery aneurysm should be a differential diagnosis in cases of mediastinal cyst and mass lesion.
巨大冠状动脉瘤是一种极其罕见的冠状动脉疾病形式。冠状动脉瘤最常见的病因是动脉粥样硬化。尽管它通常无症状，但可能有多种临床表现，包括心绞痛、心肌梗死或猝死。
一名32岁女性出现上下肢水肿、心悸和胸痛，被诊断为巨大右冠状动脉瘤，最初被误诊为纵隔囊肿。尽管计算机断层扫描（CT）提示纵隔囊肿，但经胸超声心动图显示为心包外囊肿。根据CT血管造影和冠状动脉造影结果明确诊断为右冠状动脉瘤。作为治疗方法，进行了动脉瘤切除术，她在术后第六天出院，总体健康状况良好。
在纵隔囊肿和肿块病变的病例中，冠状动脉瘤应作为鉴别诊断。
