Acute Osmotic Central Pontine Demyelination in an Alcoholic Patient With Normal Sodium Levels and a Vitamin B6 Deficiency.

Abstract

We report a Native American male in his 50s with a complex medical history including alcohol use disorder and seizure disorder who presented with complaints of generalized weakness and multiple falls. The patient was admitted for altered mental status, community acquired pneumonia, sepsis, and bacteremia. On hospital day 23, the patient reported a sudden onset of sensation of food stuck in his upper chest. Brain MRI confirmed osmotic demyelination syndrome (ODS) within the central pons. Further workup revealed this finding was likely due to malnutrition, alcoholism, hypoalbuminemia, and vitamin B6 deficiency. However, the patient presented with normonatremia throughout his entire hospital stay. After acute onset of ODS, the patient was transferred to the ICU where he continued to decline. After 68 days from initial presentation, the patient died in hospice care from myelinolysis complications. This case demonstrates a case of ODS of the central pons in a patient with normonatremia, hypoalbuminemia, and severe vitamin B6 deficiency.
