The patient presented with tachycardia, anterior neck pain and thyroid function tests revealing hyperthyroidism together with consistent ultrasonographic evidence suggesting subacute thyroiditis. Treatment with corticosteroids resulted in rapid clinical resolution. This case illustrates that subacute thyroiditis associated with viruses such as SARS-CoV-2 should be recognised as a complication of COVID-19 and considered as a differential diagnosis when infected patients present with tachycardia without evidence of progression of COVID-19 illness.<\/jats:p>","DOI":"10.1136\/bcr-2020-237336","type":"journal-article","created":{"date-parts":[[2020,8,26]],"date-time":"2020-08-26T01:35:34Z","timestamp":1598405734000},"page":"e237336","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":97,"title":["Subacute thyroiditis associated with COVID-19"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1184-4263","authenticated-orcid":false,"given":"Shaikh Abdul Matin","family":"Mattar","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Samuel Ji Quan","family":"Koh","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suresh","family":"Rama Chandran","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin Pei Zhi","family":"Cherng","sequence":"additional","affiliation":[{"name":"Department of Infectious Diseases, Singapore General Hospital, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,8,25]]},"reference":[{"key":"2025082803413351000_13.8.e237336.1","unstructured":"Ministry of Health Singapore .
