Epidemiology
Meningiomas are the most common primary tumour of the central nervous system (CNS). Data from the Central Brain Tumor Registry of the United States (CBTRUS) indicate that it accounts for 40.8% of primary brain and other CNS tumours in the US.[1][5] Tumours of the cerebral meninges are significantly more common than those of the spinal meninges (33.7% vs. 1.7%) and a higher age-adjusted incidence of meningioma has been shown to occur in black people than in white people.
Meningioma may be up to three times more likely to occur in females than males and incidence has also been shown to increase with age.[6] One population-based study from Germany reported mean age at diagnosis of 63 years.[7] The majority of patients had World Health Organization (WHO) grade 1 (benign) meningiomas (70%). WHO grade 2 (atypical) meningiomas were less common (28%) and WHO grade 3 (malignant meningiomas) were rare (3%).
