It is characterised by severe occipital pain and neck stiffness. Acute presentations are typically accompanied by fever and an inflammatory response and hence can be misdiagnosed as polymyalgia rheumatica or meningitis. Chronic relapsing presentations may be misdiagnosed as cervicogenic neck pain or occipital neuralgia. We present a patient who presented with a chronic relapsing form of crowned dens syndrome and discuss the epidemiology, typical presentation and management of this eminently treatable condition.<\/jats:p>","DOI":"10.1136\/practneurol-2017-001793","type":"journal-article","created":{"date-parts":[[2017,11,24]],"date-time":"2017-11-24T20:50:11Z","timestamp":1511556611000},"page":"57-59","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":23,"title":["Crowned dens syndrome"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6474-2666","authenticated-orcid":false,"given":"David","family":"Ledingham","sequence":"first","affiliation":[{"name":"Department of Neurology and Neurophysiology, Liverpool Hospital, Liverpool, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecilia","family":"Cappelen-Smith","sequence":"additional","affiliation":[{"name":"Department of Neurology and Neurophysiology, Liverpool Hospital, Liverpool, New South Wales, Australia"},{"name":"Ingham Institute for Applied Medical Research, South Western Sydney Clinical School, University of New South Wales, Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dennis","family":"Cordato","sequence":"additional","affiliation":[{"name":"Department of Neurology and Neurophysiology, Liverpool Hospital, Liverpool, New South Wales, Australia"},{"name":"Ingham Institute for Applied Medical Research, South Western Sydney Clinical School, University of New South Wales, Sydney, New South Wales, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2017,11,24]]},"reference":[{"key":"2025090410370169000_18.1.57.1","doi-asserted-by":"publisher","DOI":"10.1093\/rheumatology\/keh370"},{"key":"2025090410370169000_18.1.57.2","first-page":"1","article-title":"The prevalence of calcification around odontoid process and the incidence of crowned dens syndrome in the neurosurgical ward: a single institution\u2019s analysis","volume":"25","author":"Sano","year":"2017","journal-title":"Mod Rheumatol"}],"container-title":["Practical Neurology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/practneurol-2017-001793","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,9,4]],"date-time":"2025-09-04T17:37:10Z","timestamp":1757007430000},"score":1,"resource":{"primary":{"URL":"https:\/\/pn.bmj.com\/lookup\/doi\/10.1136\/practneurol-2017-001793"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,11,24]]},"references-count":2,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2018,1,16]]},"published-print":{"date-parts":[[2018,2]]}},"alternative-id":["10.1136\/practneurol-2017-001793"],"URL":"https:\/\/doi.org\/10.1136\/practneurol-2017-001793","relation":{},"ISSN":["1474-7758","1474-7766"],"issn-type":[{"value":"1474-7758","type":"print"},{"value":"1474-7766","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,11,24]]}}}
