We describe a rare case of GCTTS in an adolescent in the upper cervical spine.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case Presentation:<\/jats:title>\n                    <jats:p>A previously healthy 16-year-old boy presented with a 6-month history of numbness of right upper extremity, and had experienced a neck pain 4 months ago. Spinal MRI demonstrated a small syrinx at C2 level and a well-circumscribed extradural mass with contrast enhancement extending from the posterior arch of C1 to C2. The extradural mass was totally resected, and the syrinx underwent clinical and imaging surveillance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion:<\/jats:title>\n                    <jats:p>GCTTS should be considered in the differential diagnosis of the axial skeletal lesion although very rare. Gross-total resection is advocated in GCTTS of the upper cervical spine, and subtotal resection with meticulous lesion monitoring should be performed in unresectable cases.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/0028-3886.344600","type":"journal-article","created":{"date-parts":[[2023,8,24]],"date-time":"2023-08-24T04:05:56Z","timestamp":1692849956000},"page":"764-766","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Localized Giant Cell Tumor of the Tendon Sheath of the Upper Cervical Spine: A Case Report"],"prefix":"10.4103","volume":"70","author":[{"given":"Yu","family":"Hu","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, West China Hospital, Sichuan University, Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pathology, West China Hospital, Sichuan University, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seidu A","family":"Richard","sequence":"additional","affiliation":[{"name":"Department of Medicine, Princefield University, Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siqing","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, West China Hospital, Sichuan University, Ghana"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2022,5,3]]},"reference":[{"key":"R1-20260803","doi-asserted-by":"crossref","first-page":"e250","DOI":"10.1200\/JCO.2011.36.7482","article-title":"Giant-cell tumor of the tendon sheath in the upper cervical spine","volume":"30","author":"Teixeira","year":"2012","journal-title":"J Clin Oncol"},{"key":"R2-20260803","doi-asserted-by":"crossref","first-page":"248","DOI":"10.3171\/SPI-07\/08\/248","article-title":"Pigmented villonodular synovitis associated with pathological fracture of the odontoid and atlantoaxial instability.
