Secondary extradural spinal tumours are very rare, but they comprise m
ost of the extradural neoplasms seen in infancy and childhood. Thirty-
nine patients with this type of secondary tumour were treated in our h
ospital between 1965 and 1991. The diagnosis was proved by biopsy in e
very case. Following surgical decompression, all 35 survivors had radi
otherapy and/or chemotherapy. Their outcome is reported.
