Mature teratomas are the third most common mediastinal tumors. Giant teratoma in pediatric population is rare. A resection of giant benign teratoma in left hemithorax was performed in a 4-year-old patient. The computed tomography scan showed the presence of a large multiloculated mediastinal mass extending to the left pleural space and pleural effusion. The patient underwent total resection of the mediastinal mass via a median sternotomy associated to left anterior thoracotomy. Entry into the pleural space was performed through the sixth intercostal space to obtain safe visualization of the cavity and proceed to tumor excision. The collapsed left lung was re-expanded, and the patient was extubated. Despite the size and the surrounding structures of the teratoma, our preoperative preparation and surgical technique were effective and resulted in favorable recovery without complications and a posterior normal left lung function.
成熟畸胎瘤是第三常见的纵隔肿瘤。小儿巨大畸胎瘤罕见。一名4岁患者接受了左半胸巨大良性畸胎瘤切除术。计算机断层扫描显示存在一个大的多房性纵隔肿块，延伸至左胸腔和胸腔积液。患者通过正中胸骨切开术联合左前开胸术接受了纵隔肿块的全切除术。通过第六肋间间隙进入胸腔，以安全观察胸腔并进行肿瘤切除。萎陷的左肺重新扩张，患者拔管。尽管畸胎瘤体积较大且周围结构复杂，但我们的术前准备和手术技术有效，术后恢复良好，无并发症，左肺功能正常。
