Chordomas are rare congenital tumors which develop from remnants of the flexible spine-like structure that forms and dissolves early in fetal development (and is later replaced by the bones of the spine). Chordomas often occur near the top or the bottom of the spine, outside the dura mater, and can invade the spinal canal and skull cavity.
