Very unusual scalp recorded SEPs were seen in a case after removal of a large intraventricular meningioma. One day before death (ten days after surgery) when the patient was moribund, SEPs from the clinically and radiologically affected hemisphere in which a hematoma and thalamic infarct were found, had a normal latency and were decreased in amplitude. SEPs from the clinically and radiologically nonaffected hemisphere, where only minimal findings were seen, had an abnormally short latency (16.9 msec) and the CCT was only 3.1 msec. We do not offer any logical explanation of these unusual SEP findings from both hemispheres shortly before death.
在一例大型脑室内脑膜瘤切除术后的病例中，观察到了非常异常的头皮记录SEP（体感诱发电位）。在患者濒死（死亡前一天，即手术后十天）时，临床和影像学受影响的半球（发现有血肿和丘脑梗死）的SEP潜伏期正常，但波幅降低。临床和影像学未受影响的半球（仅发现轻微异常）的SEP潜伏期异常短（16.9毫秒），中枢传导时间仅为3.1毫秒。对于死亡前不久两个半球这些异常SEP表现，我们无法给出任何合理的解释。
