Hyponatremia is commonly seen after pituitary surgery. It generally occurs within the first week after surgery and is usually moderate and asymptomatic. However, it may be severe and prolonged in some cases. Different etiologies can explain this hyponatremia. The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is one of the most common etiologies, but other differential diagnoses must be ruled out before making this diagnosis. In this article, we present a case of prolonged hyponatremia caused by SIADH occurring after transsphenoidal surgery for a non-functioning pituitary macroadenoma. We revise the different etiologies of hyponatremia following pituitary surgery and their treatment.
