A CT scan of the neck showed right longus colli tendinitis and partially calcified excrescences from the right thyroid cartilage which raised suspicion of a cartilaginous tumour. He underwent an MRI scan of the neck to better evaluate the thyroid cartilage findings, which showed a heterogeneous mass suspicious for a chondroid tumour. He then underwent a positron-emission tomography-CT scan which showed a fluorodeoxyglucose-avid mass containing foci of calcification involving the right thyroid cartilage and adjacent strap muscle, with high standardised uptake value of 7.7. He subsequently underwent a CT-guided biopsy and an open biopsy of the right thyroid cartilage, and the results revealed gouty tophi. To our knowledge, this is the first reported case of laryngeal gout with longus coli tendinitis, both of which are rare conditions.<\/jats:p>","DOI":"10.1136\/bcr-2019-231070","type":"journal-article","created":{"date-parts":[[2019,10,25]],"date-time":"2019-10-25T12:34:30Z","timestamp":1572006870000},"page":"e231070","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Laryngeal gout mimicking chondrosarcoma with concurrent longus colli tendinitis"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8709-1694","authenticated-orcid":false,"given":"Si Ying Chrisanda","family":"Lee","sequence":"first","affiliation":[{"name":"Otorhinolaryngology, Tan Tock Seng Hospital, Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6877-2347","authenticated-orcid":false,"given":"Yijin Jereme","family":"Gan","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Tan Tock Seng Hospital, Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julian Park Nam","family":"Goh","sequence":"additional","affiliation":[{"name":"Diagnostic Radiology, Tan Tock Seng Hospital, Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yong Howe","family":"Ho","sequence":"additional","affiliation":[{"name":"Department of Pathology, Tan Tock Seng Hospital, Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ming Yann","family":"Lim","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Tan Tock Seng Hospital, Singapore, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,10,25]]},"reference":[{"key":"2025082711133784000_12.10.e231070.1","doi-asserted-by":"crossref","first-page":"140","DOI":"10.1258\/0022215021909890","article-title":"Laryngeal gout","volume":"116","author":"Tsikoudas","year":"2002","journal-title":"J Laryngol Otol"},{"key":"2025082711133784000_12.10.e231070.2","doi-asserted-by":"crossref","first-page":"343","DOI":"10.1016\/j.ijscr.2017.10.063","article-title":"Acute calcific tendinitis of the longus colli muscle masquerading as a retropharyngeal abscess: a case report and review of the literature","volume":"41","author":"Alamoudi","year":"2017","journal-title":"Int J Surg Case Rep"},{"key":"2025082711133784000_12.10.e231070.3","doi-asserted-by":"crossref","DOI":"10.4055\/cios.2018.10.2.204","article-title":"Clinical and imaging features of longus colli calcific tendinitis: an analysis of ten cases","volume":"10","author":"Suh","year":"2018","journal-title":"Clin Orthop Surg"},{"key":"2025082711133784000_12.10.e231070.4","doi-asserted-by":"publisher","DOI":"10.1177\/0194599813482289"},{"key":"2025082711133784000_12.10.e231070.5","doi-asserted-by":"crossref","first-page":"685","DOI":"10.2214\/ajr.152.4.685","article-title":"Crystal-associated arthropathies","volume":"152","author":"Rubenstein","year":"1989","journal-title":"AJR Am J Roentgenol"},{"key":"2025082711133784000_12.10.e231070.6","doi-asserted-by":"crossref","first-page":"359","DOI":"10.1016\/S0033-8389(22)00473-0","article-title":"Imaging of arthropathies. crystal disease","volume":"34","author":"Uri","year":"1996","journal-title":"Radiol Clin North Am"},{"key":"2025082711133784000_12.10.e231070.7","doi-asserted-by":"publisher","DOI":"10.1016\/S0033-8389(03)00160-X"},{"key":"2025082711133784000_12.10.e231070.8","doi-asserted-by":"publisher","DOI":"10.1055\/s-2003-43229"},{"key":"2025082711133784000_12.10.e231070.9","doi-asserted-by":"publisher","DOI":"10.1007\/s00330-005-2776-z"},{"key":"2025082711133784000_12.10.e231070.10","doi-asserted-by":"crossref","DOI":"10.1186\/s40064-016-1782-8","article-title":"Is PET-CT an accurate method for the differential diagnosis between chondroma and chondrosarcoma?","volume":"5","author":"Jesus-Garcia","year":"2016","journal-title":"Springerplus"},{"key":"2025082711133784000_12.10.e231070.11","doi-asserted-by":"publisher","DOI":"10.1177\/1759720X14542960"},{"key":"2025082711133784000_12.10.e231070.12","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1177\/000348948409300305","article-title":"Calcific tendinitis of the longus colli muscle","volume":"93","author":"Kaplan","year":"1984","journal-title":"Ann Otol Rhinol Laryngol"},{"key":"2025082711133784000_12.10.e231070.13","article-title":"Retropharyngeal calcific tendinitis mimicking a retropharyngeal phlegmon","volume":"2013","author":"Gabra","year":"2013","journal-title":"Case Rep Otolaryngol"},{"key":"2025082711133784000_12.10.e231070.14","doi-asserted-by":"crossref","unstructured":"Wesolowski JR , Mukherji SK .
