A 44-year-old man with chronic alcoholism presented with seizure and loss of consciousness. He was diagnosed with alcoholic hepatic encephalopathy, and his neurologic symptoms recovered after lactulose enema treatment. His initial serum sodium level was 141mEq/L. However, his mental state became confused after treatment with lactulose enema for five days, and his serum sodium level increased to 178mEq/L. After five days of gradual correction of serum sodium level from 178mEq/L to 140mEq/L, the patient's mental state recovered, but motor weakness in both limbs remained. Therefore, magnetic resonance imaging of the brain was performed. T2-weighted brain images showed bilateral symmetrical hyperintensities in the central pons, basal ganglia, thalami, hippocampi and unci, which were consistent with central pontine and extrapontine myelinolysis. We report a rare case of osmotic demyelination syndrome that occurred as a result of a rapid increase from a normal sodium level to hypernatremia caused by lactulose enema administered to treat alcoholic hepatic encephalopathy.
