We present the case of a 20-year-old male who experienced the triphasic response of pituitary stalk injury (central diabetes insipidus, syndrome of inappropriate antidiuretic hormone and central diabetes insipidus again) after striking his head on a concrete curb. His history and presentation highlight the importance of recognising the distinctive symptoms of each individual stage of pituitary stalk injury, and using the appropriate diagnostic tools and therapies to guide further management.<\/jats:p>","DOI":"10.1136\/bcr-2018-226725","type":"journal-article","created":{"date-parts":[[2018,10,25]],"date-time":"2018-10-25T02:35:17Z","timestamp":1540434917000},"page":"bcr-2018-226725","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Triphasic response of pituitary stalk injury following TBI: a relevant yet uncommonly recognised endocrine phenomenon"],"prefix":"10.1136","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8918-1327","authenticated-orcid":false,"given":"Ansha","family":"Goel","sequence":"first","affiliation":[{"name":"Department of Medicine, Inova Health System, Falls Church, Virginia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Freba","family":"Farhat","sequence":"additional","affiliation":[{"name":"Department of Medicine, Inova Health System, Falls Church, Virginia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chad","family":"Zik","sequence":"additional","affiliation":[{"name":"Department of Medicine, Inova Health System, Falls Church, Virginia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Jeffery","sequence":"additional","affiliation":[{"name":"Department of Medicine, Inova Health System, Falls Church, Virginia, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2018,10,24]]},"reference":[{"key":"2025082804023445000_2018.oct24_1.bcr-2018-226725.1","unstructured":"Centers for Disease Control and Prevention, 2016.
