Figure 1: (a) Diagnostic nasal endoscopy image showing persisting embryonal infundibular recess presenting as a nasal mass in the superior nasopharynx (*). (b) Contrast computed tomography brain showing a cystic lesion herniating through a bony defect anterior to shallow sella. (c) Preoperative magnetic resonance imaging constructive interference in steady state sequence showing the communication of the third ventricular floor with the cyst through a persistent embryonal infundibular recess. (d) Postoperative magnetic resonance imaging constructive interference in steady state sequence showing reduction of the sac and reconstruction of the defect
