A late complication following cranial irradiation is the induction of tumors, most of which are intracranial meningiomas. The latency period between radiation exposure and diagnosis of radiation- induced meningioma varies with the timing of the initial radiation exposure and total radiation dose. The authors report two cases of meningiomas as a result of highdose irradiation received for a PNET. Both patients underwent surgical removal of the tumor and immunohistochemical examination revealed a benign meningioma. These cases illustrate the importance of continued follow up after cranial irradiation in the pediatric population.
