If patients present with dysphagia, hoarseness, and\/or dyspnea, they may require surgery.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nOver a 7-month period, a 55-year-old female with a history of cerebral palsy developed a progressive quadriparesis accompanied by diffuse sensory loss (i.e., clumsiness of the hand\/legs and gait disturbance). The cervical spine X-rays showed atlanto-axial subluxation with instability, while the cervical MRI demonstrated \u201cpseudotumor in the retro-odontoid\u201d region. Following an occipital cervical fusion (C0-C2) surgery, her quadriparesis resolved. Nevertheless, she had persistent dysphagia that worsened over 6 months. Video fluoroscopy revealed severe mechanical stenosis of the pharynx, which was attributed to OALL extending from the C3-C6 levels. Following OALL resection through a right anterior approach utilizing diamond burrs and an ultrasonic bone curette, the dysphagia rapidly resolved.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nWe report a rare case of retro-odontoid pseudotumor successfully treated with a posterior C0-C2 cervical fusion. Additional symptomatic C3-C6 OALL, responsible for progressive dysphagia, was later managed with focal anterior OALL resection.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_286_2022","type":"journal-article","created":{"date-parts":[[2022,4,29]],"date-time":"2022-04-29T10:03:07Z","timestamp":1651226587000},"page":"184","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Dysphagia after occipital cervical fusion for retro-odontoid pseudotumor with ossification of the anterior longitudinal ligament"],"prefix":"10.25259","volume":"13","author":[{"given":"Hidenori","family":"Matsuoka","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"So","family":"Ohashi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michihisa","family":"Narikiyo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryo","family":"Nogami","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirokazu","family":"Nagasaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshifumi","family":"Tsuboi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2022,4,29]]},"reference":[{"key":"10.25259\/SNI_286_2022\/ref-1","first-page":"261","article-title":"Ossification of the cervical anterior longitudinal ligament contributing to dysphagia.
