Osmotic demyelination syndrome (ODS) is characterized by widespread degeneration of myelin within the central nervous system and has no established treatment. A limited number of cases have reported positive outcomes with plasma exchange in the treatment of ODS associated with chronic alcohol abuse or liver transplantation. We report the case of a 23-year-old female presenting with ODS following rapid correction of hyponatremia, which was attributed to hypoalbuminemia, volume overload, and malnutrition secondary to ulcerative colitis. Our patient received four plasma exchange sessions over the course of five days for a total plasma exchange of 15,500 mL. Unfortunately, the patient did not achieve significant neurologic recovery following completion of the plasma exchange regimen. This is the first report of the failure of this novel approach in the management of a patient with ODS, suggesting benefit in a limited patient population. We describe the proposed mechanism of plasma exchange in the treatment of ODS and provide a review of existing literature.
