High-dose radiation-induced meningiomas in elderly.
The authors report 2 cases of cerebral meningiomas following high-dose radiotherapy in elderly patients treated for skull basaloma. These two are the first cases over 65 years old cases reported in the literature. The pathological and clinical characteristics of high-dose radio-induced meningiomas are the following: 1) children appear particularly sensitive to the development of this tumor; 2) there is a female patient predominance, in contrast to the male dominance observed in low-dose meningioma, 3) these tumors present a peak frequency in third decade of life; 4) frequently, these tumors are atypical and recur.
