The clinical features of Ménière's disease and migraine-associated vertigo are quite similar. Both disorders are characterized by repeated vertigo spells. Several diagnostic criteria are used to diagnose migraine-associated vertigo. None of these criteria has been internationally defined,although the criteria proposed by Neuhauser are wieldy accepted. Hearing impairment is believed to be a key factor for diagnosing Meniere's disease. We report herein on a case of repeated vertigo spells with sensorineural hearing loss in the right ear. Initially,the condition was diagnosed as Meniere's disease. Treatment for improving endolymphatic hydrops did not have an effect on the vertigo spells. On careful questioning, we noted the coexistence of migraines without any aura. Treatment with Ca antagonists to prevent the migraine attacks successfully stopped the patient's vertigo spells. On the basis of this clinical course, it is safe to assume that the patient had migraine-associated vertigo with sensorineural hearing loss rather than Meniere's disease. For a patient experiencing migraines together with sensorineural hearing loss, an accurate diagnosis requires careful evaluation. The coexistence of migraines should be carefully ruled out, even if Meniere's disease with hearing loss is strongly suspected.
