Overview
The incidence of meningioma is approximately 12 per 100,000 individuals in the united states.[1] The prevalence of meningioma was estimated to be 97.5 cases per 100,000 individuals in the United States.[1] Meningiomas may appear at any age, but are most commonly noticed among patients older than 50 years of age.[2] Females are more commonly affected with meningiomas than males.[1] Meningioma usually affects individuals of the african american race. Caucasian and latin american individuals are less likely to develop meningioma.[1]
Epidemiology and Demographics
Incidence
- The incidence of meningioma is approximately 12 per 100,000 individuals in the united states.[1]
- The advent of modern sophisticated imaging studies tripled the incidence of asymptomatic meningiomas.[2]
Prevalence
- The prevalence of meningioma was estimated to be 97.5 cases per 100,000 individuals in the United States.[1]
- Meningioma is the second most common primary brain tumor worldwide.[3]
- Meningioma accounts for approximately 1 out of 3 primary brain and spinal cord tumors.[4]
- The prevalence of meningioma was estimated to be around 170,000 individuals in the United States.[1]
- Benign meningiomas account for approximately 70% of all meningioma cases.[4]
- Atypical meningiomas account for approximately 15%–25% of all meningioma cases.[4]
- Anaplastic or malignant meningiomas account for about 1%–3% of all meningioma cases.[4]
Age
- Meningiomas may appear at any age, but are most commonly noticed among patients older than 50 years of age.[2]
- Meningiomas are uncommon among patients before the age of 40 and should raise suspicion of neurofibromatosis type 2 (NF2) when found among young patients.[5]
Gender
- Females are more commonly affected with meningiomas than males.[1]
- The female to male ratio is approximately 2 to 1.[1]
- The incidence of meningioma among females is approximately 8.36 per 100,000 individuals in the united states[1].
- The incidence of meningioma among males is approximately 3.61 per 100,000 individuals in the united states.[1]
- The female to male ratio of meningiomas may be inverted among patients who are younger than 15 years of age.[1]
Race
- Meningioma usually affects individuals of the african american race. Caucasian and latin american individuals are less likely to develop meningioma.[1]
