Abstract

Introduction

Myxoma is the most common benign cardiac tumor in adults; however, in children, it is less frequent than rhabdomyoma and fibroma. It shows a female predominance, with an incidence 1.5 to 2 times higher than in males. Only 22 % of myxomas develop in the right atrium, 2 % in the ventricles, and 1 % in the atrioventricular valve.

Case report

We present the case of a 10-year-old patient admitted with obstructive symptoms with right heart failure. Diagnostic imaging, including chest X-ray, transthoracic echocardiography, and computed tomography, revealed a giant intracardiac mass. Surgical excision of the tumor was performed 48 h after admission, with favorable postoperative evolution. Histopathological examination confirmed the diagnosis of cardiac myxoma.

Conclusions

Right atrial myxomas may present with dyspnea, syncope, ascites, and symptoms of right heart failure. Early diagnosis is crucial to prevent cerebrovascular events and allow for timely surgical treatment, thereby reducing preoperative and postoperative complications.

儿科巨大右心房黏液瘤。病例报告

黏液瘤是成人最常见的良性心脏肿瘤；然而，在儿童中，它比横纹肌瘤和纤维瘤少见。该病以女性为主，发病率为男性的1.5 ~ 2倍。只有22%的黏液瘤发生在右心房，2%发生在心室，1%发生在房室瓣膜。病例报告我们报告了一个10岁的病人入院的梗阻性症状与右心衰。诊断影像，包括胸部x线，经胸超声心动图和计算机断层扫描，显示一个巨大的心内肿块。入院后48小时行手术切除肿瘤，术后进展良好。组织病理学检查证实了心脏黏液瘤的诊断。结论右心房黏液瘤可出现呼吸困难、晕厥、腹水和右心衰症状。早期诊断对于预防脑血管事件和及时手术治疗至关重要，从而减少术前和术后并发症。
