Radiation-induced cerebellar glioblastoma multiforme subsequent to treatment of an astrocytoma of the cervical spinal cord.

This originated in the zone adjacent to a field irradiated 14 years earlier after the removal of a noncontiguous astrocytoma of the spinal cord. The accepted criteria for radiation-induced tumors of the central nervous system are discussed.
