What the difference between schwannoma and meningioma?

Very different: Schwannomas are tumors of the nerve sheaths and are located outside the brain. Meningiomas are tumors of the lining of the brain and the spinal cord and not related to nerves at all. Schwannoimas require intial surgery for management typically while meningiomas can be removed by surgery or given radiation if no surgery is possible. Both are usually not cancerous.

They are diff.tumors: Schwannoma - a neoplasm originating from schwann cells (of the myelin sheath) of peripheral or sympathetic neurons, or from various cranial nerves, particularly the eighth cranial nerve; schwannomas include neurofibromas and neurilemomas. A meningioma is a tumor that arises from the meninges — the membranes that surround your brain.

The cell of origin: Schwannomas are tumors of the nerves, where meningiomas are tumors of the lining of the brain and spinal cord.
