A woman, who presented with symptoms of unilateral Ménière's disease, was found to have an adenoma of the endolymphatic sac, when an endolymphatic sac decompression was performed. Such a finding has not previously been reported. The possible role of the tumor in causing endolymphatic hydrops is discussed.
