VEGA, Jorge et al. Hyponatremia associated to pituitary adenomas: Report of three patients. Rev. méd. Chile [online]. 2009, vol.137, n.12, pp.1607-1612. ISSN 0034-9887.

Severe hyponatremia occurring as the presenting feature of hypopituitarism secondary to pituitary adenomas is rare. We report three patients with this condition: Two elderly males (74 and 78 year-old) presenting with impaired consciousness and low plasma sodium after an episode of diarrhea and a 56-year-old male presenting with impaired consciousness after an episode of vomiting. All had clinical features of hypopituitarism and pituitary adenomas were found on imaging studies. Two were subjected to a trans sphenoidal resection of the adenoma.

Keywords : Hyponatremia; Hypopituitarism; Pituitary neoplasms.
