RESUMO
Multiple Sclerosis (ME) is a chronic progressive disease characterized by relapses of demyelination that can occur anywhere in the brain stem, spinal cord and optic nerve. Since central diabetes insipidus (DI) is mainly caused by central nervous system damage (such as trauma, surgery, tumor, infection, sarcoidosis), ME is included among its possible etiologies. However, this association is not commonly described. The clinical suspicion must be made in the presence of polyuria and polydipsia or refractory hypernatremia (in patients without free access to water) during the evolution of ME. We will describe a clinical report in which this association occurred and, after the beginning of desmopressin therapy, the clinical findings were reverted.

A esclerose múltipla (EM) é uma doença crônica e progressiva que se caracteriza por surtos de desmielinização que podem atingir qualquer topografia do cérebro, medula espinhal e nervo óptico. Sendo o diabetes insípido (DI) central causado, principalmente, em virtude de danos do sistema nervoso central (tais como trauma, cirurgia, tumor, infecção, sarcoidose), a EM está inclusa entre suas possíveis etiologias. Entretanto, a ocorrência dessa associação não é comumente descrita. A suspeita clínica deve ser feita na presença de poliúria e polidipsia ou hipernatremia refratária (em pacientes privados do acesso à água) durante a evolução da EM. Descreveremos um caso em que essa associação ocorreu e, após o início da terapêutica com desmopressina, a paciente reverteu o quadro clínico.
