ムンプス難聴例 難聴・めまいと髄膜炎の合併例

Abstract

A 6-year-old girl complained of difficulty hearing four days after the onset of parotid swelling. Four days later she developed vertigo and vomiting, and was brought to our outpatient clinic. Audiograms showed total deafness of the right ear. Rotatory and horizontal nystagmus was also noted. Caloric testing revealed canal paresis (CP) on the right. Neurological examination revealed nuchal rigidity. Lumbar puncture was done, and the findings led to the diagnosis of aseptic meningitis. Various therapeutic agents including vasodilators, vitamin B, gamma globulin and steroid hormone were administered for two weeks. Although her general condition and equilibrium recovered, her hearing impairment did not improve. It was probable that meningitis following mumps infection preceded the inner ear lesion in this case and affected the inner ear by spreading through the cochlear aqueduct or internal acoustic meatus.
