Following thorough investigations, occult malignancy was ruled out. Hyponatraemia was a consistent finding which needed further classification. Additional workup including cerebral imaging and neurophysiological studies excluded cerebral vascular events and myopathies. Vasculitis screening was undertaken, and the diagnostic dilemma was revealed by the temporal arteries Doppler ultrasound which showed classical \u2018halo sign\u2019. Diagnosis of temporal arteritis was made and linked with syndrome of inappropriate antidiuretic hormone secretion, which appears to be a rare association with few instances on record. Patient was treated with high dose of prednisolone with marked improvement of clinical features.<\/jats:p>","DOI":"10.1136\/bcr-2021-246187","type":"journal-article","created":{"date-parts":[[2021,12,31]],"date-time":"2021-12-31T05:25:45Z","timestamp":1640928345000},"page":"e246187","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Atypical presentation of giant cell arteritis associated with SIADH: a rare association"],"prefix":"10.1136","volume":"14","author":[{"given":"Sadia","family":"Tariq","sequence":"first","affiliation":[{"name":"General Internal Medicine, East Surrey Hospital, Redhill, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sameh","family":"Jonny","sequence":"additional","affiliation":[{"name":"General Internal Medicine, East Surrey Hospital, Redhill, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanadi","family":"Asalieh","sequence":"additional","affiliation":[{"name":"General Internal Medicine, East Surrey Hospital, Redhill, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,12,31]]},"reference":[{"key":"2025082708073148000_14.12.e246187.1","unstructured":"NICE .
