Abstract
A patient development deteriorating mental status, quadriparesis, and severe pseudobulbar palsy with the inability to speak or swallow following orthotopic liver transplantation (OLT). Subsequently, abnormalities were found in the pons on MRI that were consistent with central pontine myelinolysis (CPM). Marked recovery occurred following transfer to the rehabilitation medicine service. Seven months following development of CPM, a mild dysarthria has persisted, but full ambulation has returned. Although no significant fluctuations in serum sodium were seen perioperatively, multiple risk factors associated with the development of CPM were present, including end-stage liver disease, a history of alcohol abuse, malnutrition, hypoxia, and use of cyclosporin medication postoperatively. This case demonstrates that the development of CPM may occur following OLT despite meticulous attention to serum sodium concentrations. We conclude that CPM is multifactorial in nature. There can be a great variation in its clinical course.
