A meningioma is a tumor that arises from the meninges â the membranes that surround your brain and spinal cord. Most meningiomas are noncancerous (benign), though rarely a meningioma may be cancerous (malignant).Some meningiomas are classified as atypical, meaning they're neither benign nor malignant but, rather, something in between.ost meningiomas are noncancerous (benign), though rarely a meningioma may be cancerous (malignant).

Overview. A meningioma is a type of tumor that grows from the protective membranes, called meninges, which surround the brain and spinal cord. Most meningiomas are benign (not cancerous) and slow growing; however, some can be malignant. Symptoms typically appear gradually and vary depending on the location and brain area affected. Because these are slow growing tumors, not all meningiomas need to be treated immediately.
