An 11-year-old boy presenting with palpitation and chest distress was found to have gross cardiomegaly on chest radiography. Subsequent echocardiography revealed an intramural giant cystic mass in the right atrium. An operative measure was planned to prevent acute cardiac tamponade and right coronary artery obstruction. The patient successfully underwent open cystectomy to remove the mass, which was located on the front wall of the right atrium and extended to the atrioventricular appendage. Histopathological examination confirmed a cystic hamartoma. To the best of our knowledge, this is the first reported case of a giant cystic hamartoma located on the right atrium.
一名11岁男孩因心悸和胸部不适就诊，胸部X线检查发现心脏明显增大。随后的超声心动图显示右心房壁内有一个巨大的囊性肿块。计划采取手术措施以预防急性心脏压塞和右冠状动脉阻塞。患者成功接受了开放性囊肿切除术以切除肿块，该肿块位于右心房前壁并延伸至房室附件。组织病理学检查证实为囊性错构瘤。据我们所知，这是首例报道的位于右心房的巨大囊性错构瘤病例。
