The authors report a case of an extremely rare extraosseous chordoma in the upper cervical spine of a 70-year-old woman, which occupied the intradural and extradural portions, simultaneously. She underwent the operation with C2,3 total laminectomy and grossly total removal and postoperative radiation therapy. Extraosseous chordoma was very rare in the literatures. In addition, it was the first reported case of the extraosseous chordoma occupeid the intradural and extradural portions, simultaneously. And extraosseous chordoma must be distinguished from ecchordosis physaliphora, which is benign nature, usually asymptomatic.
