Abstract
INTRODUCTION AND CLINICAL PRESENTATION: The authors report a case of a 5-year-old boy presenting with vision loss, right-sided hearing loss, and facial paralysis secondary to hydrocephalus causing brainstem herniation into the internal auditory canal (IAC) following cerebrospinal fluid (CSF) otorrhea. MANAGEMENT AND OUTCOME: After placement of a ventriculo-peritoneal shunt (VP shunt), the vision and facial palsy improved whilst hearing loss persisted. Imaging demonstrated partial reduction of the herniated brainstem and resolution of hydrocephalus. To our knowledge, this is the first case reported of brainstem herniation into the internal auditory canal.
