Abstract

A 60-year-old man with chronic alcoholism for 30 years was admitted to the hospital for an acute alcoholic syndrome with global confusional state, cognitive disorders, and ataxia. MRI detected bilateral mamillary bodies T 2 hypersignal related to Wernicke encephalopathy. It was treated by oral thiamine supplementation with clinical improvement. Two months later, he was rehospitalized for rapidly progressive dementia symptoms. Brain perfusion scintigraphy revealed pontine hyperperfusion and right hippocampal hypoperfusion. One month after IV thiamine supplementation, brain perfusion scintigraphy showed normalization of perfusion abnormalities in the pons and right hippocampus, leading to the diagnosis of alcoholic-related osmotic demyelination syndrome.
