The age of meningiomas.

Mathematical modeling established the age of benign (n = 12), and atypical (n = 2, red) meningiomas. Benign meningiomas were 22 ± 6.5 SD years of age, whereas atypical meningiomas were 1.5 ± 0.1 SD years of age. Benign fibrous meningiomas (n = 6) were 8.5 years older than menigothelial meningiomas (n = 6) at the time of surgery (t-test,* p < 0.05, **p < 0.001).
