Cardiac teratomas are very rare primary tumors; most are intrapericardial, while a few are intracardiac. Furthermore, most reported intracardiac teratomas are in the pediatric population, with few cases of secondary metastases from testicular teratomas reportedly manifesting in adults. Here, we report a rare case of a mature cystic teratoma in the right ventricle complicated by a bicuspid aortic valve (BAV) in an adult. Echocardiography and enhanced computed tomography (CT) were performed, and the mass was surgically excised. A pathological examination confirmed the diagnosis of a mature cystic teratoma. Meanwhile, mechanical valve replacement of the aortic valve was performed. No tumor recurrence or symptoms occurred in the 2-year follow-up. This is the first report of an adult primary intracardiac teratoma with solid hyperechoic findings on echocardiography and a BAV.
心脏畸胎瘤是非常罕见的原发性肿瘤；大多数为心包内，少数为心内。此外，大多数报道的心内畸胎瘤发生在儿科人群中，成人中报道的由睾丸畸胎瘤继发转移引起的病例较少。在这里，我们报告了一例罕见的成人右心室成熟囊性畸胎瘤合并二叶主动脉瓣（BAV）的病例。进行了超声心动图和增强计算机断层扫描（CT）检查，并进行了手术切除。病理检查证实了成熟囊性畸胎瘤的诊断。同时，进行了主动脉瓣机械瓣膜置换。在 2 年的随访中没有发现肿瘤复发或症状。这是首例超声心动图显示心脏内实质性强回声的成人原发性心内畸胎瘤合并 BAV 的病例报告。
