 note = {Meniere’s disease (MD) characteristically presents with endolymphatic hydrops (EH), which can be visualized with gadolinium-enhanced inner ear magnetic resonance imaging (MRI). Inner ear membrane rupture has been suspected to cause MD attacks, but this remains controversial. We report a case of MD coincidentally evaluated the EH using 3-Tesla MRI during a vertigo attack. A 78-year-old man with bilateral definite MD visited the hospital outpatient department due to a vertigo attack. To evaluate of endolymphatic hydrops on the attack, inner ear MRI was obtained 4 hours after intravenous injection of gadolinium agent. Vestibular EH in each ear occupied almost all vestibular endolymphatic space in contact with the oval window and herniated into the horizontal semi-circular canal. The endolymphatic space was enlarged, without collapse or mixture of contrast agent. No difference was found between ears. EH on a vertigo attack was associated with significant swelling, without obvious evidence of membranous ruptures on magnetic resonance images.},
