Overview

Epidemiology and Demographics

Incidence

  • The incidence of meningioma is approximately 11.97 per 100,000 individuals in the united states.[1]
  • With the advent of modern sophisticated imaging studies the incidence of asymptomatic meningiomas has tripled.[2]

Prevalence

  • The prevalence of meningioma was estimated to be 97.5 cases per 100,000 individuals 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]
  • In 2010, 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]

Epidemiology and Demographics

Incidence

In 1970, tumors causing symptoms were discovered in 2 out of 100,000 people, while tumors discovered without causing symptoms occurred in 5.7 out of 100,000, for a total incidence of 7.7/100,000 With the advent of modern sophisticated imaging systems such as CT scans, the discovery of asymptomatic meningiomas has tripled.

Prevalance

Most common primary brain tumour. Ninety-two percent of meningiomas are benign. Eight percent are either atypical or malignant One to two percent of all autopsies reveal meningiomas that were unknown to the individuals during their lifetime, since there were never any symptoms Meningiomas account for approximately 1 out of 3 primary brain and spinal cord tumours and are the most common brain tumour in adults. Benign meningiomas are low-grade (grade I) tumours that account for approximately 70% of all meningiomas. Atypical meningiomas are low-grade (grade II) tumours that account for approximately 15%–25% of all meningiomas. Anaplastic or malignant meningiomas are high-grade (grade III) tumours that account for about 1%–3% of all meningiomas.


Age

They are uncommon in patients before the age of 40 eningiomas becoming more likely with age. appear in men, they are more likely to be malignant. Meningiomas may appear at any age, but most commonly are noticed in men and women age 50 or older,

Gender

Meningiomas are more common in women, with a ratio of 2:1 intracranially and 4:1 in the spine. Atypical and malignant meningiomas are slightly more common in males They are uncommon in patients before the age of 40 and should raise suspicion of neurofibromatosis type 2 (NF2) when found in young patients
