Our purpose is to describe typical computed tomography and magnetic resonance imaging findings in encephalopathies in the emergency. The focus of this article are the most frequent toxic and acquired metabolic diseases and their preferential sites of involvement, such as hepatic encephalopathy, hypoglicemia, nonketotic hyperglycemia, osmotic demyelination, posterior reversible encephalopathy syndrome, uremia, illegal drug abuse, carbon monoxide poisoning, and hypoxic-ischemic encephalopathy. The radiologist must be able to identify the most usual patterns of lesion in computed tomography and magnetic resonance imaging in these settings.
