Magnetic resonance imaging showed the pituitary gland pushed upward by NPC. Hypopituitarism due to an intracranial tumor and the extracellular volume excess due to chemotherapy caused hyponatremia and polyuria. As the intracranial tumor was diminished by chemotherapy and irradiation, pituitary hormones were normalized. In patients with T4 NPC, pituitary-adreno-cortical function should be endocrinologically evaluated before treatment.<\/jats:p>","DOI":"10.1159\/000276689","type":"journal-article","created":{"date-parts":[[2010,1,15]],"date-time":"2010-01-15T03:25:48Z","timestamp":1263525948000},"page":"347-351","source":"Crossref","is-referenced-by-count":3,"title":["Hypopituitarism and Hyponatremia in a Case with Nasopharyngeal Carcinoma"],"prefix":"10.1159","author":[{"given":"Toshiyuki","family":"Kokatsu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mamoru","family":"Tsukuda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,1,13]]},"container-title":["ORL"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000276689","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T08:28:49Z","timestamp":1777710529000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000276689"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,1,13]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000276689","archive":["Portico"],"relation":{},"ISSN":["0301-1569","1423-0275"],"issn-type":[{"value":"0301-1569","type":"print"},{"value":"1423-0275","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,1,13]]}}}
