BACKGROUND
Spontaneous intracranial hypotension may be associated with neuro-otological symptoms that might mimic Menière's disease.
CASE PRESENTATION
We report the case of a 53-year-old male presenting bi-frontal headache with recurrent spells of vertigo, left fluctuating hearing loss, and tinnitus. Dedicated brain and inner ear Magnetic Resonance Imaging, including a post-contrast 4 hours delayed FLAIR sequence, revealed typical signs of spontaneous intracranial hypotension associated with endolymphatic hydrops involving the left saccule and cochlea.
CONCLUSIONS
Audio vestibular manifestations mimicking Menière's disease in spontaneous intracranial hypotension could be explained by endolymphatic hydrops, which can be detected using dedicated magnetic resonance imaging sequences.
背景
自发性颅内低血压可能与神经耳科学症状相关，这些症状可能类似于梅尼埃病。
病例介绍
我们报告了一例 53 岁男性病例，其表现为双额头痛，伴有反复发作的眩晕、左侧波动性听力损失和耳鸣。专门的脑部和内耳磁共振成像，包括对比后 4 小时延迟 FLAIR 序列，显示了自发性颅内低血压的典型征象，伴有内淋巴积水，累及左侧球囊和耳蜗。
结论
自发性颅内低血压中模仿梅尼埃病的听觉前庭表现可以通过内淋巴积水来解释，而内淋巴积水可以通过专门的磁共振成像序列来检测。
