Abstract

In a 70-year-old man who had angina, exercise-induced ventricular tachycardia, and presyncopal symptoms, transthoracic and transesophageal echocardiography disclosed a large atrial mass that resembled a myxoma. Subsequent evaluation by magnetic resonance imaging identified the mass as an intracardiac lipoma attached to the posterior wall of the right atrium, a diagnosis that was confirmed by surgical intervention. Thus, the diagnostic utility of magnetic resonance imaging as an adjunct to echocardiographic evaluation of intracardiac masses was demonstrated.

摘要

在一名患有心绞痛、运动诱发室性心动过速和晕厥前期症状的70岁男性患者中，经胸和经食管超声心动图显示出一个类似黏液瘤的巨大心房肿块。随后通过磁共振成像进行的评估确定该肿块为附着于右心房后壁的心脏内脂肪瘤，手术干预证实了这一诊断。因此，证明了磁共振成像作为超声心动图评估心脏内肿块辅助手段的诊断效用。
