A 43-year-old female who had suffered from paranoid reaction attempted suicide with city gas. She was admitted to an emergency hospital in a comatose state, regained consciousness the next day and was discharged 12 days after. However, on the 21st day after the poisoning, behavioral anomalies and staggering appeared. She was readmitted into another emergency hospital with the diagnosis of an "interval" form of acute carbon monoxide poisoning. She was performed hyperbaric oxygen therapy 42 times until the 53rd day after the accident. Nevertheless, her symptoms did not improve and remained in a state like an apallic syndrome. With little promise of improvement, she was moved to our hospital, and hyperbaric oxygen therapy further continued for 40 times which resulted in a remarkable recovery. Repeat EEGs were performed. On the 32nd day, EEG showed an abnormality consisting of generalized delta waves. On the 56th day, the abnormal EEG improved slightly with more alpha activity. EEG was normalized 126 days after. The X-ray CT scan on the 32nd day revealed low densities in the bilateral globus pallidus and the deep white matters adjacent to the frontal horns of the lateral ventricle and in the semioval centers. On the 57th day, these low density areas were depicted more clearly by the X-ray CT scan, which became less marked on the 73rd day. MRI was performed 3 times.(ABSTRACT TRUNCATED AT 250 WORDS)
一名43岁患有偏执反应的女性试图用城市燃气自杀。她以昏迷状态被送入一家急诊医院，第二天苏醒，并在12天后出院。然而，在中毒后的第21天，出现了行为异常和蹒跚步态。她因急性一氧化碳中毒的“中间型”诊断被再次送入另一家急诊医院。在事故发生后的第53天，她接受了42次高压氧治疗。然而，她的症状并未改善，仍处于去皮层综合征状态。由于改善希望渺茫，她被转至我院，继续进行了40次高压氧治疗，结果显著康复。进行了多次重复脑电图检查。在第32天，脑电图显示由广泛性δ波组成的异常。在第56天，异常脑电图稍有改善，α活动增多。脑电图在126天后恢复正常。第32天的X线CT扫描显示双侧苍白球以及侧脑室额角相邻的深部白质和半卵圆中心有低密度影。在第57天，这些低密度区域在X线CT扫描中显示得更清晰，在第73天变得不那么明显。进行了3次磁共振成像检查。（摘要截断于250字）
