レルモワイエ症候群について

Lermoyez's Syndrome

I．はじめに

　1919年にLermoyez^5）が初めて報告したレルモワイエ症候群の報告例は少なく，その病態に関しては，ほとんど明らかにされていない。今回，突発性難聴の疑いで入院させたところ，当科入院中にレルモワイエ症候群の初回めまい発作をおこした症例を経験した。従来から問題になっているめまい発作前後の症状の発現順序と，これを裏づける聴力検査および平衡機能検査所見の推移に関して，また種々の治療を試みた結果としての効果面からみたレルモワイエ症候群の発現機序や病態に関して，若干の考察を加えて報告する。

　A follow-up study of Lermoyez's syndrome is reported. The patient was suddenly seized with deafness and increasing tinnitus. Thereafter, he had repeated vertiginous spells accompanied by succeeded improvement of hearing acuity. This cochlear effects recurred at intervals of several hours after vertigo. Gaze nystagmus to the right direction was observed during attacks and disappeared next day repeatedly, but spontaneous nystagmus to the left direction was recorded under closed eyes which was pronounced during mental calculation. Although cochlear and vestibular signs and symptoms did not improved by the steroid and isosordit (as a miniature of glycerol test), low frequency deafness and tinnitus was treated with stellate ganglion blocks and other vasodilators.

　In addition to these clinical findngs herpetic vesicles appeared over the gluteal region 32 days later.

　It is still questionable whether Lermoyez's syndrome is associated endolymphatic pressure or vascular insufficiency of labyrinth.
