Excerpt
Meningiomas not only occur sporadically or in the context of neurofibromatosis type 2, but can also be induced by radiation [
7]. High-dose radiation-induced meningiomas (Mrad) predominantly arise after radiation for other brain tumors (often in childhood) with doses of 40–60 Gy. Most low-dose Mrad have been detected in patients receiving 3–4 Gy to the scalp for tinea capitis [
6,
9]. Analysis of these tumors is paradigmatic for radiation-induced tumorigenesis, particularly in the absence of a prior tumor and chemotherapy and a model for collateral exposure surrounding the target of high-dose irradiation. So far, little molecular overlap between Mrad and sporadic meningiomas has been detected [
6,
9]. …
