A 46-year-old male patient was found unconscious in his room. There were remnants of burned-out charcoal briquettes. ⋯ MR images on Day 15 showed findings caused by white matter encephalopathy, and signal intensity in the left temporal lobe was decreased. To our best knowledge, it is very rare to see abnormal signal changes in the temporal lobe on radiological imaging of the patients who is suspected CO poisoning in acute phase because it has been reported that white matter encephalopathy after CO poisoning is commonly seen in delayed timing.
