Persisting embryonal infundibular recess (PEIR) is a rare anomaly of the development of the posterior pituitary wherein there is a defect in the third ventricular floor. Earlier reports have found PEIR descending only up to the sella. However, this is the first case of PEIR presenting as a pulsatile nasal mass. A 35-year-old female presented to the otorhinolaryngologist with hyposmia. Diagnostic nasal endoscopy revealed a pulsatile nasal mass. Magnetic resonance imaging revealed a cystic lesion extending from the third ventricular floor to the nasal cavity. There was no associated hydrocephalus or empty sella. The case was successfully managed by the endoscopic endonasal transsphenoidal approach.
持续性胚胎漏斗隐窝（PEIR）是一种罕见的垂体后叶发育异常，其第三脑室底部存在缺陷。早期报告发现PEIR仅下降至蝶鞍。然而，这是首例表现为搏动性鼻腔肿物的PEIR病例。一名35岁女性因嗅觉减退就诊于耳鼻喉科医生。诊断性鼻内镜检查发现一个搏动性鼻腔肿物。磁共振成像显示一个囊性病变从第三脑室底部延伸至鼻腔。无相关脑积水或空蝶鞍。该病例通过鼻内镜下经蝶窦入路成功治疗。
