A case of Mondini dysplasia with recurrent Streptococcus pneumoniae meningitis.
Mondini's dysplasia is a developmental anomaly of the middle ear characterized by cochlear malformation with dilation of the vestibular aquaduct, vestibule, and ampullar ends of the semicircular canals. These deformities may result in a connection between subarachnoid space and the middle ear resulting in recurrent episodes of meningitis. Additionally, it is commonly associated with hearing impairment. We describe here a boy with recurrent meningitis and unilateral sensorineural hearing loss. Mondini dysplasia was demonstrated with computed tomographic scans of the temporal bones in the search for pathogenesis of recurrent meningitis.
