Cardiac myxoma, the most common primary cardiac tumor, usually develops in the left atrium. Right atrial myxomas are rare, especially those accompanied by pulmonary tumor embolism. We describe a case of a right atrial myxoma with a large tumor embolus in the left pulmonary artery. A 74-year-old man was referred to our hospital for the treatment of a right atrial tumor. Upon echocardiography, the right atrial tumor was revealed to have a mobile and tail-like surface projection. In addition, computed tomography showed that an embolus was wedged into the left pulmonary artery. We performed an emergency surgery to remove both the right atrial tumor and the pulmonary embolus. Histopathological examination revealed them both to be myxoma. Right atrial myxoma with a large pulmonary tumor embolus is a serious condition and emergency surgery to remove both cardiac tumors and pulmonary emboli should be performed to avoid the risk of sudden death.
心脏黏液瘤是最常见的原发性心脏肿瘤，通常发生于左心房。右心房黏液瘤较为罕见，尤其是伴有肺肿瘤栓塞的情况。我们报告一例左肺动脉内有巨大肿瘤栓子的右心房黏液瘤病例。一名74岁男性因右心房肿瘤被转诊至我院治疗。经超声心动图检查，发现右心房肿瘤表面有可移动的尾状突出。此外，计算机断层扫描显示一个栓子楔入左肺动脉。我们进行了急诊手术，切除了右心房肿瘤和肺栓子。组织病理学检查显示二者均为黏液瘤。伴有巨大肺肿瘤栓子的右心房黏液瘤是一种严重疾病，应进行急诊手术切除心脏肿瘤和肺栓子，以避免猝死风险。
