Abstract：
BACKGROUND: Left atrial appendage aneurysm is a rare cardiac mass, with only a few cases reported. There are usually no specific symptoms, and a few patients visit the doctor with symptoms.
METHODS: A 20-year-old male presented to our hospital with a \"pericardial cyst found by medical evaluation in another hospital for 2 years.\" Cardiac ultrasound performed at clinics of our hospital suggested a cystic dark area in the left ventricular lateral wall and the anterior lateral wall, consistent with a pericardial cyst and mild mitral regurgitation. After further relevant examinations and ruling out contraindications, an excision of the left atrial appendage aneurysm was performed under general anesthesia and cardiopulmonary bypass with beating-heart. The postoperative pathological results identified that: (left atrial appendage) fibrocystic wall-like tissue with a focal lining of the flat epithelium, consistent with a benign cyst.
CONCLUSIONS: Left atrial appendage aneurysms are rare and insidious. They are usually found by chance during medical evaluations. If the location is not good or the volume is too large, then compression symptoms or arrhythmia, thrombosis and other concomitant symptoms will occur. Surgical resection is presently the only effective radical cure for a left atrial appendage aneurysm.

摘要：
背景：左心耳动脉瘤是一种罕见的心脏肿块，只有少数病例报告。通常没有特定的症状。和一些病人去看医生的症状。
方法：一名20岁男性患者到我院就诊，在另一家医院经医学评估发现心包囊肿2年。“在我们医院诊所进行的心脏超声检查提示左心室侧壁和前侧壁有一个囊性暗区，与心包囊肿和轻度二尖瓣反流一致。经过进一步的相关检查并排除禁忌症，左心耳动脉瘤切除术是在全身麻醉和心脏跳动的体外循环下进行的.术后病理结果确定：（左心耳）纤维囊壁样组织，局灶性上皮为扁平上皮，符合良性囊肿.
结论：左心耳动脉瘤是罕见且隐匿的。它们通常是在医学评估期间偶然发现的。如果位置不好或体积太大，然后是压迫症状或心律失常，会出现血栓形成和其他伴随症状。手术切除是目前唯一有效的治疗左心耳动脉瘤的方法。
