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.
梅尼埃病（MD）的特征是内淋巴积水（EH），可通过钆增强内耳磁共振成像（MRI）观察到。内耳膜破裂被怀疑会引起 MD 发作，但这仍然存在争议。我们报告了一例 MD 病例，该病例在眩晕发作期间使用 3-Tesla MRI 偶然评估了 EH。一名 78 岁男性因双侧明确 MD 就诊于医院门诊，因眩晕发作。为了评估发作时的内淋巴积水，在静脉注射钆剂后 4 小时获得内耳 MRI。每只耳朵的前庭 EH 占据了与卵圆窗接触的几乎所有前庭内淋巴空间，并疝入水平半规管。内淋巴空间扩大，没有塌陷或造影剂混合。双耳之间没有差异。EH 在眩晕发作时与明显肿胀相关，磁共振图像上没有明显的膜破裂证据。
