Core Tip

Core tip: Osmotic demyelination syndrome (ODS) is a devastating neurologic disorder often associated with a precipitous rise in serum sodium. Here we describe a rare case of extrapontine myelinolysis that developed after a rapid correction of symptomatic hyponatremia induced by pituitrin to treat a patient with massive hemoptysis. Because ODS is mainly an iatrogenic disease, effective prevention is mandatory. Through an analysis of the previous literature, the risk factors, clinical characteristics, and outcomes of vasopressin (pituitrin)-associated ODS are discussed in this article.
