A rare case of epicardial cyst diagnosed at surgery was presented. A 64-year old woman was admitted for evaluation of a mediastinal mass shown by echocardiography to be adjacent to both ventricles. Computed tomography (CT) and magnetic resonance imaging (MRI) studies were performed. On CT, there was evidence of an abnormal mass lesion at the lateral side of the outlet of the right ventricle. The CT number of the mass was 24.7, suggesting cystic lesion. MRI revealed that the intensity of the lesion signal was higher than that of subcutaneous fat on the T2 weighted image. On the T1 weighted image, a low intensity was identified in the same region. During operation a mass originating from the epicardium was diagnosed as an epicardial cyst.
本文报道了一例手术确诊的心外膜囊肿罕见病例。一名64岁女性因超声心动图显示纵隔肿块紧邻双侧心室而入院评估。进行了计算机断层扫描（CT）和磁共振成像（MRI）检查。CT显示右心室流出道外侧有异常肿块病变。肿块的CT值为24.7，提示为囊性病变。MRI显示，在T2加权图像上，病变信号强度高于皮下脂肪。在T1加权图像上，同一区域显示低信号强度。手术中，一个起源于心外膜的肿块被诊断为心外膜囊肿。
