Meningiomas are extra-axial tumors and represent the most common tumor of the meninges.They are a non-glial neoplasm that originates from the meningocytes or arachnoid cap cells of the meninges and are located anywhere that meninges are found, and in some places where only rest cells are presumed to be located

56. Meningiomas can be graded in various ways - eg, site of origin, encroachment of surrounding tissues and histological grading
Definition of meningioma. : a slow-growing encapsulated typically benign tumor arising from the meninges and often causing damage by pressing upon the brain and adjacent parts.
The prognosis for individuals with grade I meningiomas is very favorable . Five to seven percent of meningiomas are a grade II tumor . These brain tumors grow a little faster and may recur within five years after removal.
Meningiomas grow on the surface of the brain (or spinal cord), and therefore push the brain away rather than growing from within it. Most are considered “benign” because they are slow-growing with low potential to spread. Meningioma tumors can become quite large. Diameters of 2 inches (5 cm.) are not uncommon.
Grade one meningiomas are the most common and what most people call benign. They are slow-growing tumors that are meningo-filial, fibrous and transitional.
