Intradural chordoma without bone involvement. Case report and review of the literature.

Chordomas are most commonly of extradural origin and associated with bone destruction. The authors describe a rare case of an intradural chordoma. To the best of their knowledge, this is the first case in which multiple lesions were found intradurally without bone involvement; the lesions were disseminated through the thoracolumbosacral spinal cord and extended into the paraspinal muscles, and metastatic lesions in the cervical cord were also present.
