Abstract

We report a case of a 52-year-old man who presented with iatrogenic bilateral nasoethmoidal meningoencephaloceles following endoscopic nasal surgery performed in a neighboring country 8 years ago. Imaging studies, including computed tomography and magnetic resonance imaging of the paranasal sinuses and anterior skull base, demonstrated bilateral meningoencephaloceles and a suspicious intracranial lesion. In view of the intracranial lesion and size of the skull base defect, an external approach via a bicoronal flap was used for exploration and repair. Intraoperative findings revealed the suspicious intracranial lesion to be a retained piece of gauze. The patient underwent a successful removal of the foreign body and repair of the skull base defect. Postoperative recovery was uneventful. To our knowledge, an iatrogenic intracranial foreign body following an endonasal endoscopic procedure has never been reported before. Laryngoscope, 2011
