High dose radiation-induced meningiomas are a rare, severe and late complication 
of craniospinal radiotherapy for brain tumors. Radiation-induced meningiomas 
are, according to the literature, several times more frequent than radiogenic 
gliomas and sarcomas. It is suggested that every new case of radiogenic 
meningioma has to be reported to elucidate this particular pathologic entity 
with its many grey areas. In addition to high dose radiation-induced 
meningiomas, intracranial meningiomas were observed in patients who underwent 
low-dose radiation for tinea capitis in childhood, applied en mass to immigrants 
coming to Israel from the North Africa and the Middle East during the 1950. 
Authors summarize the data on radiogenic meningiomas from the literature and, as 
the previous radiotherapy may confer a low, but life-long risk for meningioma 
occurrence, they suggest that surveillance MRI after high dose cerebrospinal 
radiotherapy should be extended to several (3-5) decades after radiotherapy.
