title: Extraosseous spinal chordoma: radiographic appearance.
abstract: The authors describe a chordoma arising within the soft tissues of the spinal canal (rather than from a vertebral body) in a 6-year-old boy. The lesion was entirely extradural as shown by CT and MR; this was confirmed at surgery.
