No neurological impairment of the extremities was noted. Computed tomography revealed a C2\u2013C7 osteophyte formation, mainly in front of the vertebral bodies. Moreover, magnetic resonance imaging showed cervical spinal cord compression by a soft tissue mass posterior to the odontoid process of the axis. Therefore, we diagnosed a cervical spine injury with an isolated symptom of C2\u2013C3 dysesthesia due to a retro\u2010odontoid pseudotumor. He did not undergo surgical intervention and was transferred to a rehabilitation hospital on day 11 for pain control.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our report could be useful to emergency physicians dealing with similar cases of cervical symptoms following trauma.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ams2.685","type":"journal-article","created":{"date-parts":[[2021,7,24]],"date-time":"2021-07-24T01:56:00Z","timestamp":1627091760000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Retro\u2010odontoid pseudotumor with uncommon presentation of cervical spine injury"],"prefix":"10.1002","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4219-1728","authenticated-orcid":false,"given":"Shota","family":"Kikuta","sequence":"first","affiliation":[{"name":"Department of Emergency and Critical Care Medicine Hyogo Emergency Medical Center Kobe City Hyogo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Ishihara","sequence":"additional","affiliation":[{"name":"Department of Emergency and Critical Care Medicine Hyogo Emergency Medical Center Kobe City Hyogo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yukihisa","family":"Yagata","sequence":"additional","affiliation":[{"name":"Department of Emergency and Critical Care Medicine Hyogo Emergency Medical Center Kobe City Hyogo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1503-7864","authenticated-orcid":false,"given":"Shigenari","family":"Matsuyama","sequence":"additional","affiliation":[{"name":"Department of Emergency and Critical Care Medicine Hyogo Emergency Medical Center Kobe City Hyogo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinichi","family":"Nakayama","sequence":"additional","affiliation":[{"name":"Department of Emergency and Critical Care Medicine Hyogo Emergency Medical Center Kobe City Hyogo Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,7,23]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2018.10.011"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00586-013-2681-0"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.1780331015"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-019-03187-z"},{"key":"e_1_2_6_6_1","first-page":"1658129","article-title":"Retroodontoid pseudotumor related to development of myelopathy secondary to atlantoaxial instability on Os Odontoideum","volume":"2018","author":"Hamard M","year":"2018","journal-title":"Case Rep.
