Central pontine myelinolysis: a rare finding in hyperosmolar hyperglycemia.

Central pontine myelinolysis (CPM) is a heterogeneous nervous system disease of pontine demyelination, usually caused by rapid correction of hyponatremia. In the present study, we report a unique case of a 46-year-old man with a hyperglycemic state complicated with CPM. MRI demonstrated a high signal on T2 and symmetric restricted diffusion in the pontine. In conclusion, the clinical case described confirmed that the hyperosmolar state inherent in hyperglycemia was a likely cause of CPM.
