Nasopharyngeal teratomas are rare neoplasms, often presenting as neonatal airway obstruction. A case is presented of a full-term neonate with a mass which filled the oropharynx, nasopharynx and the entire left nasal cavity and extended through the left nares. Airway obstruction necessitated orotracheal intubation immediately after delivery. Cerebrospinal fluid rhinorrhea was suggested and computerized tomography was initially interpreted as a nasoethmoidal encephalocele. After a craniotomy failed to reveal a dural defect, the mass was completely removed via the nose and nasopharynx. The infant was extubated and had an uneventful recovery. This case illustrates the problem of confusing a teratoma for an encephalocele and demonstrates a pitfall in the interpretation of computerized tomography of these lesions.
鼻咽畸胎瘤是一种罕见的肿瘤，常表现为新生儿气道梗阻。本文报告一例足月新生儿，其肿物充满口咽、鼻咽及整个左侧鼻腔，并经左鼻孔向外延伸。气道梗阻使得患儿在出生后立即进行了气管插管。怀疑有脑脊液鼻漏，计算机断层扫描最初诊断为鼻筛部脑膨出。在开颅手术未发现硬脑膜缺损后，经鼻和鼻咽部将肿物完整切除。患儿拔除气管插管后恢复顺利。该病例说明了将畸胎瘤误诊为脑膨出的问题，并展示了这些病变在计算机断层扫描解读中的一个陷阱。
