Background:Chordomas must be considered among the differential diagnoses for extradural spinal tumors, especially involving the clival or sacrococcygeal regions. They are often locally invasive and destructive to the osseous structures from which they arise, but rarely extend intradurally. Here, we report a unique chordoma that was intradural and spanned nearly four subaxial cervical vertebral levels.Case Description:We report the case of an atypical intradural chordoma that spanned four subaxial levels of the cervical spine in an 81-year-old female. It also extended through multiple neural foramina but did not invade or destroy the bony elements of the cervical vertebrae. Notably, it demonstrated sizable extension into the deep carotid triangle abutting the internal jugular vein.Conclusion:This case involved an extraosseous, intradural, four-level subaxial cervical chordoma that demonstrated significant extraspinal extension into the anterior soft tissues of the neck.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
