Mature cystic teratomas exhibit a variety of tissues within their pathology. In adults, teratomas typically originate in the gonads. However, one of the rarest origins is the lung, making intrapulmonary teratoma (IPT) exceedingly uncommon. In infants, extragonadal teratomas are more common, with only two cases of IPT reported in the literature. While the clinical presentation in infants and adults is similar, fever appears to be unique to infant cases. We present a case of a one-year-old female who exhibited respiratory distress and fever. A chest X-ray revealed an opaque right hemithorax, initially leading to a diagnosis of pneumonia. Despite intravenous (IV) antibiotic treatment, there was no improvement. A subsequent chest computed tomography (CT) scan revealed a large mass with heterogeneous densities occupying the entire right hemithorax, indicative of IPT. The mass was successfully excised, and the infant was discharged on the 11th postoperative day without complications. This case adds to the limited literature on giant IPT in infants compared to the two previously published cases.
成熟囊性畸胎瘤在其病理中表现出多种组织。在成年人中，畸胎瘤通常起源于性腺。然而，最罕见的起源之一是肺，这使得肺内畸胎瘤（IPT）极为罕见。在婴儿中，性腺外畸胎瘤更为常见，文献中仅报道了两例IPT。虽然婴儿和成年人的临床表现相似，但发热似乎是婴儿病例所特有的。我们报告一例1岁女性，表现为呼吸窘迫和发热。胸部X线显示右半胸不透明，最初诊断为肺炎。尽管进行了静脉抗生素治疗，但病情并无改善。随后的胸部计算机断层扫描（CT）显示一个密度不均匀的大肿块占据了整个右半胸，提示为IPT。肿块成功切除，婴儿术后第11天出院，无并发症。与之前发表的两例病例相比，该病例增加了关于婴儿巨大IPT的有限文献。
