MIELINÓLISE OSMÓTICA ASSOCIADA A POLIDIPSIA PSICOGÊNICA: RELATO DE CASO

Abstract

To report a very rare case of extrapontine osmotic myelinolysis with an exclusively cortico subcortical presentation. Case description: Patient with psychogenic polydipsia evolving with hyponatremia, correction of serum sodium levels and consequent episode of alteration in the level of consciousness. Months later, in routine MRI, lesions characteristic of extrapontine OM were evidenced. Conclusion: As the clinical presentation of OM is nonspecific and the radiological aspect can be characteristic, knowing the different imaging patterns is of paramount importance to narrow the differential diagnosis for the various professionals who may face this type of disease.
