Pediatric Ménière's disease with disassociated cochlear and vestibular symptoms: a case report.

Background:Typical Ménière's disease (MD) rarely occurs in childhood. Compared to adults, age-associated changes in vestibular function can occur during infancy and childhood. Previous case reports may have lacked some audiovestibular tests in children. It is worthwhile to follow a child with MD to observe how vertigo and hearing loss could progress under an insufficient vestibular system. Case Description:A 14-year-old pediatric patient with disassociated episodes between vertigo and hearing loss was finally diagnosed with MD. He was diagnosed with probable MD due to lack of objective evidence of hearing loss in his first two admissions. However, in his third admission, he had hearing loss even without attack of vertigo and was finally diagnosed. By listing the patient's audiovestibular auxiliary tests in a chronological order, we might follow the progress of pediatric MD. Gadolinium-enhanced magnetic resonance imaging (Gd-MRI) might be sensitive to reflect endolymphatic hydrops (EH). Medications including corticosteroids might be effective for both hearing loss and vertigo. Conclusions:In pediatric MD, vestibular and cochlear symptoms may occur and progress independently. Audiovestibular evaluation, especially caloric tests and cervical vestibular evoked myogenic potential (cVEMP), can be useful for pediatric MD. Gd-MRI can be sensitive for detecting EH. Both systemic and postauricular administration of corticosteroids might be effective in alleviating vertigo and improving hearing. Prolongation of the follow-up period of pediatric MD is warranted.
