Extrapontine myelinolysis (EPM) is one of the complications occurring secondary to rapid correction of hyponatremia, and is, along with central pontine myelinolysis encompassed by the more recent term osmotic demyelination syndrome.

In the vast majority of cases, it is associated with central pontine myelinolysis but it can also (rarely) occur as an isolated entity.
