问题 单项选择题 A1/A2型题

患者,青年女性,发热、畏寒、出汗数日就诊,查体发现二尖瓣区杂音,如图为收缩期心尖五腔超声图像,该疾病最可能的诊断为()

A.左心房内血栓

B.二尖瓣脱垂

C.二尖瓣赘生物

D.风心二尖瓣狭窄

E.黏液瘤

答案

参考答案:C

解析:如图所示,二尖瓣前瓣上可见实性回声附着,并且患者有发热、畏寒、出汗病史,首先考虑感染性心内膜炎伴二尖瓣赘生物形成;左心房内血栓应附着在左心房内壁,基底部较宽,活动不明显;二尖瓣脱垂是指二尖瓣叶在心室收缩期脱入左心房(向左心房侧膨出),而与本题中超声图像并不符合;左心房黏液瘤往往附着在左心房壁上,而非二尖瓣瓣叶上;风湿性心脏病二尖瓣狭窄表现为二尖瓣钙化、舒张期二尖瓣开放受限等,本题中未出现与此相关的图像,所以D为最适合的答案。
