The patient was afebrile. There were no visible signs of infection on routine oropharyngeal examination. Initial workup was unremarkable except for elevated erythrocyte sedimentation rate, C-reactive protein and creatinine. CT of the cervical spine ruled out any fracture or cervical spine injury but showed an area of calcification, prevertebral oedema and fluid collection inferior to the anterior arch of C1. MRI of the cervical spine also showed prevertebral oedema and fluid collection in the retropharyngeal space from the skull base to the C3 level without abnormal surrounding enhancement that supported the diagnosis of acute calcific tendonitis of the longus colli muscle rather than an infectious process. There was significant improvement of symptoms 48\u2009hours after initiating treatment with systemic steroids. The patient remains asymptomatic 6\u2009months after treatment.<\/jats:p>","DOI":"10.1136\/bcr-2017-219684","type":"journal-article","created":{"date-parts":[[2017,5,27]],"date-time":"2017-05-27T07:45:13Z","timestamp":1495871113000},"page":"bcr-2017-219684","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["A rare cause of acute dysphagia: acute calcific tendonitis of the longus colli muscle"],"prefix":"10.1136","volume":"2017","author":[{"given":"Hanadi","family":"Abou Dargham","sequence":"first","affiliation":[{"name":"Family Medicine, Sacred Heart Hospital, Allentown, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Faton","family":"Bytyci","sequence":"additional","affiliation":[{"name":"Sacred Heart Hospital, Allentown, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Shuman","sequence":"additional","affiliation":[{"name":"Family Medicine, Sacred Heart Hospital, Allentown, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anton","family":"Stolear","sequence":"additional","affiliation":[{"name":"Sacred Heart Hospital, Allentown, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,5,27]]},"reference":[{"key":"2025082723514467000_2017.may27_1.bcr-2017-219684.1","doi-asserted-by":"crossref","first-page":"1636","DOI":"10.2106\/00004623-199411000-00006","article-title":"Acute calcific retropharyngeal tendinitis. clinical presentation and pathological characterization","volume":"76","author":"Ring","year":"1994","journal-title":"J Bone Joint Surg Am"},{"key":"2025082723514467000_2017.may27_1.bcr-2017-219684.2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1468-2982.1986.0603169.x"},{"key":"2025082723514467000_2017.may27_1.bcr-2017-219684.3","doi-asserted-by":"crossref","first-page":"77","DOI":"10.3171\/spi.2007.6.1.77","article-title":"Calcific retropharyngeal tendinitis: a frequently missed diagnosis.
