Incidental meningiomas in autopsy study

Abstract

Two hundred thirty-one cases of incidental meningiomas found at autopsy at the Montefiore Medical Center during the period from 1950 to 1982 were reviewed. The prevalence of incidental meningiomas increased with age, and was highest in people 80 years of age or older. The male to female ratio was 1 to 3. The relative size of the tumors also increased with age. Multiple meningiomas were found in 8.2% of the cases; none of them had stigmata of neurofibromatosis.
