| Summary: | Methanol is a non-drinking type of alcohol used for industrial and automotive purposes. Methanol itself is not dangerous, but its harmful metabolites may cause the accumulation of acid in the blood, leading to metabolic acidosis, permanent blindness, and death. In this case report study, the case was a 28-year-old Nepalese man who was admitted in a semi-unconscious state to the emergency department. A working diagnosis of methanol poisoning was made. After more than two weeks, he succumbed to death due to a worsening cerebral infarction. At autopsy, extensive hemorrhagic infarction was observed, involving bilateral cerebral hemispheres. Well-defined subcortical hemorrhages leading to laminar necrosis were seen at the frontoparietal lobes. Cystic or lacunar necrosis was present at the basal ganglia. The brainstem showed the presence of duret hemorrhage. The man died approximately three weeks after the methanol ingestion. This case highlights the important pathological changes and accumulating effects of methanol in the brain. © 2023 Shahid Beheshti University of Medical Sciences. All rights reserved.
