Abstract

Wernicke encephalopathy (WE)is a rareneurologicaldisorderinducedby vitaminB1 deficiency(thiamine), which is associated with high risks of Korsakoff psychosis and death in case of untimely initiation ofspecific therapy. In addition to clinical and laboratory data, magnetic resonance imaging (MRI) of the brain, which has a fairly high specificity, plays an important role in detecting this pathology. However, a high degree of awareness ofWE by radiologists is necessary for correct interpretation ofMRI data.This publication presents two own clinical observations ofpatients who underwent surgical interventions on the gastrointestinal tract, complicated by Wernicke encephalopathy, MRI and clinical manifestations, the key features ofthe etiology and pathogenesis ofthis pathological process are described.
