title: Altered mental status in a young, healthy female.
abstract: A young previously healthy patient presented with fever and altered mental status. Her evaluation would eventually reveal a profound hyponatremia in the setting of a viral meningoencephalitis. This case report reviews the evaluation of hyponatremia and treatment options for syndrome of inappropriate antidiuretic hormone hypersecretion, her ultimate diagnosis.
