Papillary fibroelastoma is one of the most common benign primary cardiac tumor after myxoma. However, it is rare to originate from Eustachian valve. A 44-year-old woman was pointed out the right atrial tumor during admission for vasospastic angina. On two-dimensional echocardiogram, the tumor was found in the right atrium, and easily moved to the right ventricle. At operation, the tumor originated from Eustachian valve, and was resected together with the valve by means of extracorporeal circulation. The size of tumor was 57 mm in length, and the histological diagnosis was papillary fibroleastoma. The post-operative course was uneventful.
乳头肌纤维弹性瘤是继黏液瘤之后最常见的原发性心脏良性肿瘤之一。然而，起源于欧氏瓣的情况却很罕见。一名44岁女性因血管痉挛性心绞痛入院时被发现右心房有肿瘤。二维超声心动图显示肿瘤位于右心房，且很容易移动至右心室。手术中发现肿瘤起源于欧氏瓣，并通过体外循环将肿瘤与瓣膜一并切除。肿瘤长径为57毫米，组织学诊断为乳头肌纤维弹性瘤。术后病程平稳。
