摘要

當腦幹梗塞不表現多采多姿症候群，卻只有尋常而模糊的症狀時，其臨床診斷往往顯得很困難。腦幹聽性反應(ABR)是評估腦幹病變有效、迅速、方便又花費不高的篩檢工具。ABR以往比較常用來輔助脫髓鞘病變與腦幹腫瘤的診斷；但對於腦幹梗塞有其價值。本部曾經歷1名64歲無高血壓、糖尿病或心臟血管疾病的腦幹梗塞患者，臨床上只以暈眩為主訴，經ABR檢查懷疑有腦幹病變後，再由磁振影像(MRI)證實。

When a patient with brainstem infarct presents with only the ambiguous complaint of dizziness instead of multiple neurological syndromies and any other clinical symptoms and signs, it is often difficult to define the nature of the dizziness. Auditory brainstem responses (ABR) are sensitive indicators for demyelinating and neoplastic diseases as well as brainstem stroke. Utilizing its electrophysiological character for evaluating central auditory function, ABR could be ancillary to the neurological examination and act as a convenient and inexpensive screening test for brainstem stroke before the expensive image study such as magnetic resonance image (MRI) is performed. We encountered a patient with brainstem infarct, who had no risk factors such as hypertension, cardiovascular disease and diabetes mellitus, and who presented with the vague complaint of dizziness only. We detected brainstem infarct with ABR and comfirmed it with MRI later.
