The age-adjusted incidence rate for intracranial meningiomas increased from 0.6 patients per 100,000 population in the period 1963-1972 to 1.5 in 1983-1992 for males and correspondingly from 1.0 to 2.8 for females. An incidence fall-off after 70 years of age was evident, presumably because many older patients with small and asymptomatic meningiomas were undiagnosed due to the low autopsy rate in the population. The prognosis for survival in meningioma patients improved over the study period and was related to type of tumor histology and age at diagnosis.
颅内脑膜瘤的年龄调整发病率在男性中从1963 - 1972年期间的每10万人0.6例增加到1983 - 1992年的1.5例，女性相应地从1.0例增加到2.8例。70岁以后发病率明显下降，可能是因为许多患有小的无症状脑膜瘤的老年患者由于人群中尸检率低而未被诊断出来。在研究期间，脑膜瘤患者的生存预后有所改善，并且与肿瘤组织学类型和诊断时的年龄有关。
