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
