Typical symptoms include neck pain, torticollis, and neurological deficits, but dizziness has rarely been reported in association with AAD\/AAS. We describe an adolescent girl who presented with non-spinning dizziness, neck pain, and torticollis after prolonged head flexion and extension. Neurological examination showed rightward torticollis without nystagmus. Cervical spine imaging revealed atlantoaxial rotatory dislocation and fixation, while CT angiography confirmed patency of both vertebral arteries. Conservative management with cervical traction was ineffective, and surgical reduction with C1\u2013C2 fixation and fusion was performed. The patient experienced complete resolution of dizziness and torticollis postoperatively without complications. This image-based report describes a rare case of AAD in which dizziness was the main presenting symptom. This case highlights that cervical instability should be considered in the differential diagnosis of dizziness.<\/jats:p>","DOI":"10.3390\/diagnostics16131949","type":"journal-article","created":{"date-parts":[[2026,6,23]],"date-time":"2026-06-23T17:11:49Z","timestamp":1782234709000},"page":"1949","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Atlantoaxial Dislocation Presenting with Dizziness"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2983-8697","authenticated-orcid":false,"given":"Seoyeon","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Neurology, Inha University Hospital, Inha University College of Medicine, Incheon 22332, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1508-2024","authenticated-orcid":false,"given":"Ji-Soo","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Neurology, Seoul National University College of Medicine, Seoul 03080, Republic of Korea"},{"name":"Dizziness Center, Clinical Neuroscience Center, Department of Neurology, Seoul National University Bundang Hospital, Seongnam 13620, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin Sup","family":"Yeom","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Seoul National University College of Medicine, Seoul National University Bundang Hospital, Seoul 13620, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7114-4157","authenticated-orcid":false,"given":"Ngoc Quyen","family":"Nguyen","sequence":"additional","affiliation":[{"name":"Spine Surgery Unit, Polyclinic and Premier Healthcare Center, 108 Military Central Hospital, Hanoi 100000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2491-3544","authenticated-orcid":false,"given":"Beomseok","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of Neurology, BJ Center for Comprehensive Parkinson Care and Rare Movement Disorders, Chung-Ang University Health Care System Hyundae Hospital, Namyangju 12013, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2027-6341","authenticated-orcid":false,"given":"Hyo-Jung","family":"Kim","sequence":"additional","affiliation":[{"name":"Biomedical Research Institute, Seoul National University Bundang Hospital, Seongnam 13620, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"69","DOI":"10.1097\/WCO.0000000000000161","article-title":"Cervicogenic causes of vertigo","volume":"28","author":"Hain","year":"2015","journal-title":"Curr.
