合併疑似單側腦幹病變之可能偏頭痛性眩暈:病例報告

Probable Migrainous Vertigo with A Probable Unilateral Brainstem Lesion: A Case Report

Abstracts


「可能偏頭痛性眩暈」與偏頭痛性眩暈有關,若病程發生變化時,應考慮中樞性的病變,若對影像學的檢查結果有疑慮時,可以借助神經耳科學的方法。一28歲男性,苦於左側耳鳴及聽障已經7年,自1年前開始罹患「可能偏頭痛性眩暈」,每每於發作前左側耳鳴會加重。大約在半年前的一次發作時,左側耳鳴加重及頭暈持續了3週,磁振造影顯示左側中腦出現了可疑處,由於眼振電圖、兩耳溫差測試及左側前庭誘發肌性電位檢查呈現異常,而且在給予腦循環促進劑治療後,聽力均有進步,可見當時應有左側腦幹的病變。爾後半年,在適當地使用鎮定劑或助眠劑後,情況依然穩定。

Probable migrainous vertigo (probable MV) is relative with migrainous vertigo (MV). A central lesion should be impressed if the disease-course changes. An oto-neurologic study is recommended to confirm a dubious image finding. A 28-year-old male presented left tinnitus and hearing block for 7 years. Unfortunately, he has been bothered with probable MV since one year ago. Left tinnitus always exacerbated before each attack. However, about half a year ago, left exacerbated tinnitus and dizziness has persisted for three weeks. Magnetic resonance image/angiogram of brain showed a dubious finding in his left midbrain. Electrony-stagmogram, caloric test and left vestibular evoked myogenic potential showed abnormal waves; in addition, his hearing ability improved after treated with a brain circulatory promoter, so there must be something wrong in his left brainstem. In the following half a year, it was uneventful because a sedative or a hypnotics has been properly used.
