title: Metastatic adenocarcinoma presenting with central diabetes insipidus.
abstract: The case of a previously healthy 63-year-old female with metastatic adenocarcinoma to the hypothalamus presenting with central diabetes insipidus is presented. The patient was found to have metastatic disease isolated to her hypothalamus on brain magnetic resonance imaging as well as a water deprivation test consistent with central diabetes insipidus. The patient had a decrease in symptoms of polyuria and polydypsia as well as a decrease in urine volumes after treatment with intranasal vasopressin. Even though a rare occurrence, physicians should consider metastatic adenocarcinoma in patients with recent-onset polyuria and polydypsia.
