摘要

Aimed to test the hypothesis that endolymphatic hydropsin Meniere＇s disease （MD） may be secondary tootitis media, history of a patient who developed MDas a complication of otitis media was reviewed. Theinner ear was imaged using a 3.0 Tesla MR systempost-intravenous injection of gadolinium-tetraazacyclododecane-tetraacetic acid （Gd-DOTA） in a standardsingle dosage （0.1 mmol/kg）. Both t2-spc-rst-tra-iso（T2-weighted） and heavily T2-weighted 3-dimensionalfluid-attenuated inversion recovery magnetic resonanceimaging [hT（2）W-3D-FLAIR] sequences were applied.As a result, in the T2-weighted images, the perilymphand endolymph, cerebrospinal fluid surrounding theeighth nerve （N8）, and middle ear granulation tissueshowed intense signals. In the hT（2）W-3D-FLAIR images,evident enhancement by Gd-DOTA was observedin the middle ear cavity and the perilymphatic compartmentsof the cochlea. Cochlear endolymphatic hydropswas implicated by the enlarged scala media in the basalturn. In general, the Gd-DOTA uptake in the vestibulewas weak, and signs of vestibular endolymphatic hydropswere obvious. The N8 on the diseased side wasalso significantly enhanced. To conclude, endolymphatichydrops in MD may be induced by otitis media.Cochlear endolymphatic hydrops in MD secondary tootitis media may not follow the classical pattern.
