A 44-year-old male patient was referred to our department with unremarkable physical examination and laboratory data due to a mass which was incidentally found in the right atrial during a routine examination. Transthoracic and transesophageal echocardiography revealed a 46 × 30 mm, well-delimited, nonmobile mass in the superior portion of the right atrium. Besides the intracardiac mass, another low density was detected in adjacent pericardial cavity at cardiac computed tomography; he extracardiac mass appeared to be caused by invasive growth from the intracardiac mass. An operation was performed through right anterolateral minithoracotomy with the patient under hypothermic cardiopulmonary bypass. During operation, it was found that the surface of the right atrium was covered by an adipose mass (30 × 40 mm; Figure 2A). Intracardiac mass also showed yellow adipose tissue (40 × 50 mm; Figure 2B). Both parts of the mass infiltrated the myocardium. The mass was resected completely; and right atrium was reconstructed by using bovine pericardium pad. After the operation, the pathology confirmed the both intracardiac and extracardiac tissues as lipoma; transthoracic echocardiogram showed the atrial mass was removed completely and the left ventricular ejection fraction was normal. The patient's postoperative course was uneventful and he was discharged home after 7 days.
一位 44 岁的男性患者因在常规检查中偶然发现右心房内有一肿块而被转至我科。经胸超声心动图和经食管超声心动图显示，右心房上部有一个 46×30mm、界限清楚、无活动度的肿块。除了心内肿块外，心脏计算机断层扫描还在相邻的心包腔内发现了另一个低密度影；心外肿块似乎是由心内肿块的侵袭性生长引起的。患者在低温体外循环下行右前外侧小开胸手术。术中发现右心房表面覆盖着脂肪肿块（30×40mm；图 2A）。心内肿块也显示黄色脂肪组织（40×50mm；图 2B）。肿块的两部分均浸润心肌。肿块被完全切除，并用牛心包垫重建右心房。术后病理证实心内和心外组织均为脂肪瘤；经胸超声心动图显示心房肿块完全切除，左心室射血分数正常。患者术后恢复顺利，7 天后出院回家。
