[Hyponatremia: an unusual case report]

Abstract

Hyponatremia is a frequent finding and asks for a rapid diagnostic evaluation. We report a case of recurrent hyponatremia secondary to an adrenal insufficiency of medicamentous and tuberculous origin. This case illustrates the importance of a rapid etiologic diagnosis of hyponatremia and allows us to review adrenal insufficiency of tuberculous origin. It also stresses the danger of potential drug interactions in case of corticosteroid substitution.
