We report a patient suffering from delayed encephalopathy 21 days after an acute CO intoxication. The initial magnetic resonance (MR) images in the acute stage show a recent infarct corresponding to a right middle cerebral artery (MCA) stenosis. MR images on the 24th day post-intoxication show typical changes of delayed encephalopathy. These changes were much more prominent on the areas corresponding to right MCA territory while less severe on the other parts. The finding suggests an ischemic component contributes to carbon monoxide related delayed brain injury.
我们报告了一例急性 CO 中毒后 21 天发生迟发性脑病的患者。急性期的初始磁共振（MR）图像显示与右侧大脑中动脉（MCA）狭窄相对应的近期梗死。中毒后第 24 天的 MR 图像显示出典型的迟发性脑病变化。这些变化在对应于右侧 MCA 区域的部位更为明显，而在其他部位则较轻。这一发现表明缺血性成分有助于一氧化碳相关的迟发性脑损伤。
