Three Synchronous Tumors Discovered in SIADH Investigation
Syndrome of Inappropriate Antidiuretic Hormone Secretion (SIADH) is a common cause of euvolemic hyponatremia which has many possible etiologies such as tumors (mainly lung cancers). We present a case of a 79-year old women hospitalized due to microcytic anemia with transfusion need and hyponatremia due to SIADH. Three primary tumors without known metastasis were discovered. The case shows the importance of studying causes of hyponatremia.
