Abstract

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare cause of nasal airway obstruction that clinically mimics choanal atresia, but needs to be differentiated from the latter because of the widely divergent modes of management. We present a case of CNPAS, to highlight the importance of recognizing the classic signs of CNPAS on cross-sectional imaging.

摘要

先天性鼻梨状孔狭窄（CNPAS）是鼻气道阻塞的一种罕见原因，临床上类似于后鼻孔闭锁，但由于治疗方式差异很大，需要与后者进行鉴别。我们报告一例CNPAS病例，以强调在横断面成像上识别CNPAS典型征象的重要性。
