Seven months following severe crushing closed-head trauma with initial excellent recovery, neurologic deficits referable to the right mesencephalon abruptly developed in a 28-year-old man. Computed tomography demonstrated a cystic midbrain lesion with apparent communication with the aqueduct (later confirmed at autopsy). Brain-stem auditory evoked potentials after the clinical deterioration showed depression of amplitude of wave V, compared with predeficit records, only when the ear contralateral to the brain-stem lesion was stimulated.
一名28岁男性在严重闭合性头部挤压伤后最初恢复良好，七个月后突然出现了与右中脑相关的神经功能缺损。计算机断层扫描显示中脑有一个囊性病变，明显与导水管相通（尸检后得到证实）。临床病情恶化后进行的脑干听觉诱发电位显示，与缺损前记录相比，仅在刺激脑干病变对侧耳朵时，V波振幅降低。
