[Mondini's dysplasia: a rare cause of recurrent meningitis in childhood]

Abstract

Recurrent meningitis in children may be due to immune deficiency or abnormal communication of CSF spaces with mucosal spaces (basal skull fractures, encephalocele, etc.). We report a 6-year-old boy, suffering from recurrent meningitis and sensorineural hearing loss. CT scans of the temporal bones demonstrated a bilateral Mondini dysplasia. In patients with this congenital inner ear anomaly, recurrent meningitis may be due to a CSF-middle ear fistula. We think that it is necessary to investigate all patients with recurrent meningitis and sensorineural hearing loss with CT scans of the temporal bones.
