However, here, we present an 82-year-old female in whom stabilization for 6 months in a soft cervical collar results in mass and symptom regression.<\/jats:p>\n <\/jats:sec>\n \n Case Description:<\/jats:title>\n An 82-year-old female developed a right hemiparesis. Her deficit was attributed to a cervical magnetic resonance imaging (MRI) that demonstrated a T2-hypointense retro-odontoid mass compressing the spinal cord, causing intramedullary T2 hyperintensity. Posterior surgical stabilization\/decompression was recommended, but she declined surgery. She was treated with a soft cervical collar and gradually improved. Over 6 months, the right incomplete hemiparesis resolved. The follow-up MRI demonstrated spontaneous regression of the retro-odontoid mass, resolution of cord compression, and no residual hyperintense T2 cord signal. She remains stable and asymptomatic 2 years later.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Although surgery remains the standard for symptomatic ROP, strict cervical immobilization \u2013 even with a soft collar \u2013 may be a reasonable option in selected (i.e., particularly elderly) patients.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_1391_2025","type":"journal-article","created":{"date-parts":[[2026,2,20]],"date-time":"2026-02-20T06:53:05Z","timestamp":1771570385000},"page":"102","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Symptomatic retro-odontoid pseudotumor regressing after strict immobilization with a soft cervical collar: A case report"],"prefix":"10.25259","volume":"17","author":[{"given":"Masahiro","family":"Kawanishi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naokado","family":"Ikeda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yutaka","family":"Ito","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kunio","family":"Yokoyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makoto","family":"Yamada","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akira","family":"Sugie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hidekazu","family":"Tanaka","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2026,2,20]]},"reference":[{"key":"10.25259\/SNI_1391_2025\/ref-1","doi-asserted-by":"crossref","first-page":"760","DOI":"10.1177\/0961203314567752","article-title":"Unusual case of tetraparesis in a patient with systemic lupus erythematosus","volume":"24","author":"Ishchenko","year":"2015","journal-title":"Lupus"},{"key":"10.25259\/SNI_1391_2025\/ref-2","doi-asserted-by":"crossref","first-page":"599","DOI":"10.1017\/cjn.2018.319","article-title":"Regression of degenerative retro-odontoid pseudotumour treated in a collar","volume":"45","author":"Klas","year":"2018","journal-title":"Can J Neurol Sci"},{"key":"10.25259\/SNI_1391_2025\/ref-3","doi-asserted-by":"crossref","first-page":"e0329","DOI":"10.2106\/JBJS.CC.18.00329","article-title":"Regression of retro-odontoid pseudotumor using external orthosis without atlantoaxial fusion: A case report","volume":"9","author":"Nakazawa","year":"2019","journal-title":"JBJS Case Connect"},{"key":"10.25259\/SNI_1391_2025\/ref-4","doi-asserted-by":"crossref","first-page":"687","DOI":"10.7196\/SAMJ.2016.v106i7.9861","article-title":"Resolution of a periodontoid rheumatoid pannus mass in an elderly patient treated with a rigid cervical collar: A case report and literature review","volume":"106","author":"Oseni","year":"2016","journal-title":"S Afr Med J"},{"key":"10.25259\/SNI_1391_2025\/ref-5","doi-asserted-by":"crossref","first-page":"100","DOI":"10.1016\/j.wneu.2018.10.011","article-title":"Retro-odontoid pseudotumor without radiologic atlantoaxial instability: A systematic review","volume":"121","author":"Robles","year":"2019","journal-title":"World Neurosurg"}],"container-title":["Surgical Neurology International"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/surgicalneurologyint.com\/symptomatic-retro-odontoid-pseudotumor-regressing-after-strict-immobilization-with-a-soft-cervical-collar-a-case-report\/","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/symptomatic-retro-odontoid-pseudotumor-regressing-after-strict-immobilization-with-a-soft-cervical-collar-a-case-report\/","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,20]],"date-time":"2026-02-20T06:53:06Z","timestamp":1771570386000},"score":1,"resource":{"primary":{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/symptomatic-retro-odontoid-pseudotumor-regressing-after-strict-immobilization-with-a-soft-cervical-collar-a-case-report\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,2,20]]},"references-count":5,"alternative-id":["10.25259\/SNI_1391_2025"],"URL":"https:\/\/doi.org\/10.25259\/sni_1391_2025","relation":{},"ISSN":["2152-7806","2229-5097"],"issn-type":[{"value":"2152-7806","type":"electronic"},{"value":"2229-5097","type":"print"}],"subject":[],"published":{"date-parts":[[2026,2,20]]},"article-number":"102"}}
