Myxomas account for a majority of the reported primary cardiac tumors that are relatively rare, and biatrial myxomas in an atrial septal defect are extremely rare. Here, we present the case of a healthy 79-year-old woman who was referred to our hospital after a giant mass in the left atrium was incidentally detected by transthoracic echocardiography. Although she was asymptomatic, we surgically resected the mass soon after admission, considering the risk of embolism. During the surgery, we observed the giant bilateral tumor in an atrial septal defect, which was, on pathological evaluation, found to be a myxoma. < Differential diagnosis of intra-cardiac tumors is sometimes difficult because they are relatively rare. Cardiac magnetic resonance imaging is the most useful imaging modality for the differential diagnosis of intra-cardiac tumors. We describe a case wherein a large myxoma was detected in an atrial septal defect. It is useful to know that myxoma in an atrial septal defect can grow to a large size as it tends to grow in the direction of blood flow.>.
黏液瘤是相对罕见的已报道的原发性心脏肿瘤中的大多数，而房间隔缺损中的双房黏液瘤极为罕见。在此，我们报告一例79岁健康女性的病例，经胸超声心动图偶然发现左心房有巨大肿块后转诊至我院。尽管她没有症状，但考虑到栓塞风险，入院后不久我们就对肿块进行了手术切除。手术过程中，我们在房间隔缺损处观察到巨大的双侧肿瘤，经病理评估，发现是黏液瘤。<心脏内肿瘤的鉴别诊断有时很困难，因为它们相对罕见。心脏磁共振成像对于心脏内肿瘤的鉴别诊断是最有用的成像方式。我们描述了一例在房间隔缺损中发现大黏液瘤的病例。了解房间隔缺损中的黏液瘤可因倾向于沿血流方向生长而长到很大尺寸是很有用的。>
