Abstract

During the follow-up of recurrent pneumonia in a 9-month-old girl, rhinorrhea with discharge of a positional and intermittent nature was discovered. Radiological assessment was requested to detect any skull base openings and cerebrospinal fluid (CSF) leakage. T2-weighted MR cisternography showed bilateral inner ear dysplasia, communication of the internal auditory canal with the vestibule, and effusion in the right middle ear. Intrathecal contrast-enhanced MR cisternography revealed a CSF fistula from the right internal auditory canal to the Eustachian tube. The patient was operated upon on the right side, and the presence of a CSF leak near the oval window was confirmed. No adverse effects were seen during the short-term and long-term follow-up. Diagnosing this case required special attention, careful examination, and relevant investigations to find the site of CSF leakage in this patient with bilateral inner ear dysplasia.
