A young and healthy woman presented with progressive dyspnea on exertion. An echocardiogram showed a giant right atrial mass. Cardiac CT angiography provided the most accurate estimate for the tumor size, while 2-D echo, 2-D, and 3-D trans-esophageal echo underestimated the dimensions of the cardiac tumor when referenced by the surgical specimen. We also calculated the growth rate of the right atrial myxoma to be at least 1.2 mm per month based on a normal chest CT 54 months before her presentation. Surgical pathology confirmed typical features of cardiac myxoma in the right atrium.
一位年轻健康的女性在活动时出现进行性呼吸困难。超声心动图显示右心房有一个巨大的肿块。心脏 CT 血管造影术为肿瘤大小提供了最准确的估计，而二维超声心动图、二维和三维经食管超声心动图在与手术标本比较时低估了心脏肿瘤的尺寸。我们还根据她就诊前 54 个月的正常胸部 CT 计算出右心房黏液瘤的生长速度至少为每月 1.2 毫米。手术病理证实了右心房心脏黏液瘤的典型特征。
