Question

Which is the most common benign tumor that arises from the coverings of the brain (the meninges)?

a) Glioma
b) Meningioma
c) Schwannoma
d) Astrocytoma

Answer 1

The most common benign tumor that arises from the meninges of the brain is meningioma.

Step-by-step explanation:

The most common benign tumor that arises from the coverings of the brain (the meninges) is meningioma. Meningiomas are typically slow-growing tumors that originate from the meningeal cells of the arachnoid mater, one of the three layers of meninges surrounding the brain. They are usually noncancerous and can develop anywhere along the outer surface of the brain. Gliomas (Option a) and astrocytomas (Option D) are tumors that arise from glial cells, which are supportive in the brain, but they do not originate from the meninges. Schwannomas (Option c) arise from Schwann cells, which produce the myelin sheath covering nerves, and they are more commonly associated with peripheral nerves rather than the meninges.

Meningiomas are often detected incidentally or may cause symptoms based on their size and location, and surgical removal is a common treatment approach for symptomatic cases.
