Left atrial appendage aneurysm is a rare abnormality and a diagnostic dilemma in patients with cardiomegaly. Patients most commonly present with atrial tachyarrhythmias and thromboembolic events. Resection of the aneurysm is usually curative. We report herein the case of a 27-year-old man with massive left atrial appendage aneurysm diagnosed incidentally in the course of pre-operative evaluation for a non-cardiac surgery. The marked cardiomegaly detected in a routinely ordered pre-operative chest X-ray and the history of previous episodes of palpitation accompanied by chest discomfort guided us to the diagnosis. The diagnosis was made by transthoracic echocardiography and confirmed by angiography and then surgery.
左心耳动脉瘤是一种罕见的异常情况，对于心脏扩大的患者来说是一个诊断难题。患者最常见的表现是房性快速性心律失常和血栓栓塞事件。切除动脉瘤通常可治愈。我们在此报告一例27岁男性患者，在非心脏手术的术前评估过程中偶然发现巨大左心耳动脉瘤。术前常规胸部X线检查发现明显的心脏扩大，以及既往有心悸伴胸部不适发作史，这些引导我们做出了诊断。通过经胸超声心动图做出诊断，并经血管造影证实，随后进行了手术。
