Malignant astrocytoma following radiotherapy for craniopharyngioma.

ABSTRACT

Radiation induced gliomas are uncommon. Occurrence of glioma following radiotherapy for craniopharyngiomas is extremely uncommon and only eight case reports have been so far published. We present our experience with one similar case of temporal gliomas occurring twelve years following radiotherapy for a sub totally excised craniopharyngioma. Although the exact mechanism of gliomas formation is unclear, their occurrence following conventional radiotherapy is a distinct possibility and signifies a poor prognosis.
