ABSTRACT

Extrapontine myelinolysis is a rare entity that is related to sodium fluctuations, mainly hyponatremia, although it is also linked to other metabolic conditions such as diabetes mellitus. We present the case of a 48-year-old woman who suffers from diabetes insipidus treated with adiuretin, which was temporarily suspended and presented hypernatremia that was treated; During this metabolic correction process, he presented a picture of obtundation associated with flaccid quadriparesis. Magnetic resonance imaging was performed with 1.5 Tesla Siemens equipment, observing hyperintense lesions with a demyelinating appearance on T2 and FLAIR sequences at the level of the body and splenium of the corpus callosum and the base nuclei. The clinical evolution of the patient is described and the pathophysiology of this entity is discussed.
