We report on the case of a 32-year-old woman with tuberculous meningitis (TBM) with electroencephalogram (EEG) output displaying triphasic waves (TWs). The EEG on day 8 revealed generalized slowing, frontal bilateral TWs, a background of 2Hz delta waves, and no epileptiform activity. The patient's condition improved slowly with antituberculosis chemotherapy treatment. A follow-up EEG on day 34 showed marked improvement, with no TWs, background activity improved to a 12Hz symmetric alpha wave pattern, and no epileptiform activity, as before. To our knowledge, this is the first report of TWs observed in a TBM case.
我们报告了一例 32 岁女性结核性脑膜炎（TBM）患者的病例，其脑电图（EEG）表现出三相波（TWs）。第 8 天的 EEG 显示广泛减慢，双侧额部 TWs，背景为 2Hz 德尔塔波，无癫痫样活动。患者的病情在抗结核化疗治疗后缓慢改善。第 34 天的后续 EEG 显示明显改善，无 TWs，背景活动改善为 12Hz 对称的阿尔法波模式，无癫痫样活动，与之前相同。据我们所知，这是首例观察到 TBM 病例中 TWs 的报告。
