A Case Series of Imaging Nuances of Persistent Craniopharyngeal Canal – Connecting the Pharynx to Brain!

Abstract

Persistent craniopharyngeal canal (PCPC) is a rare congenital anomaly arising from the incomplete closure of the craniopharyngeal canal during embryological development. Imaging plays a crucial role in identifying and understanding the anatomical characteristics and guiding appropriate management strategies. We present a series of four cases of PCPC with varied and unexpected clinical presentations along with details of imaging nuances and management implications, emphasizing the importance of radiodiagnosis in guiding appropriate management strategies. From incidental diagnosis in an asymptomatic adult to a symptomatic syndromic child, the PCPC has a wide clinico-radiological spectrum of presentation as well as management challenges.
