Background

Meningiomas are the most common primary tumours of the central nervous system. As the majority of meningiomas are benign, initial management often consists of observation only. Consequently, estimates on meningioma incidence are generally considered too low, with many registries mainly depending on pathology notifications. With additional notification sources, this study provides more complete population-based estimates on the incidence, prevalence, and prognostic impact of meningioma diagnosis in the Netherlands.
