EC Clinical and Medical Case Reports

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

We report the case of a patient operated for gastric tumor in whom the post-operative assessment finds a deep hyponatremia quickly corrected causing an apyretic conscience disorder related to osmotic demyelination syndrome confirmed on MRI.
