Neurosurgical management of a rare congenital supratentorial neurenteric cyst with associated nasal dermal sinus: Case report

Abstract

The authors describe the case of a patient with the classic clinical presentation and radiographic features of a nasal dermal sinus with an associated intracranial cyst; however, histopathology revealed that the intracranial cyst was neurenteric instead of the typical epidermoid or dermoid cyst. Preoperative assessment included CT and MRI, which revealed a direct communication between the patient's nasal polypoid lesion and the anterior skull base via the foramen cecum. At the hands of a multidisciplinary plastic surgery and neurosurgery team, the patient underwent concurrent gross-Total resection of the nasal polypoid lesion, the intracranial intradural cystic lesion, and their interconnecting tract.
