Cavitating Osmotic Demyelination Syndrome Following Correction of Chronic Hyponatremia in Sheehan's Syndrome: A Novel Case Report.

Introduction: Rapid correction of hyponatremia can result in osmotic demyelination syndrome (ODS). Sheehan's syndrome, a rare pituitary disorder caused by severe postpartum hemorrhage, is a potential cause of chronic hyponatremia. This case report describes a rare progression of extrapontine myelinolysis to central pontine myelinolysis, ultimately leading to ODS, following the correction of chronic hyponatremia associated with Sheehan's syndrome.
