: Central pontin myelinolysis and extra-pontin myelinolysis (CPM/EPM) implies the clinical picture after rapid recovery of hyponatremia or hyponatremia alone. SPM/EPM picture can occur without hyponatremia. Findings such as dysarthria, dysphagia, tetraparesia/plegy accompanies the clinical table. Our case was also diabetic, but there were no electrolyte imbalance in admission. The presence of diarrhea in medical history of the patient might indicate a short-term undetected electrolyte imbalance. In our diabetic case that has borderline metabolic status and lack of any detected electrolyte imbalance, we decided to present SPM/EPM table together with literature information.
