benign brain tumor originating from the arachinoid region of the brain; constitute about 15 percent of all primary brain tumors, and are twice as frequent in women as in men.
Hard, usually vascular tumor of the membranes covering the brain and spinal cord. Usually grows slowly. May invade the skull causing bone erosion and pressure on brain tissues. Usually occurs in adults, in some cases following head injury.
a rare noncancerous tumor developing in the protective membranes covering the brain called the meninges; can cause headaches and problems with vision and mental function
Tumour of the meninges, usually benign and slow-growing.
a tumor arising in the meninges which surround the brain and spinal cord; usually slow growing and sometimes malignant
a benign (non-cancerous) tumour that grows out of the meninges, particularly the one known as the arachnoid layer (so called because it looks like a web)
a benign tumour arising from the meninges
a common brain tumor that originates from the meninges, the thin membranes or lining that cover the brain and spinal cord
an extramedullary tumor arising from the meninges surrounding the spinal cord rather from within the cord itself
a non-cancerous tumour that grows out of the meninges, for reasons unknown
a tumor that arises from the membranes that cover the brain and surround the central nervous system (i
a tumor that develops from the membranes that surrounds the brain and spinal cord
a tumor that grows from the meninges, the membrane that surrounds the brain and spinal cord.
A benign, encapsulated tumor usually arising in the arachnoidea layer of the meninges. Most frequently seen in adults.
Benign brain tumors of arachnoid origin.
Benign central nervous tissue tumor (usually) which is derived from meningeal coverings of the brain.
A tumor of the meninges, the membrane that covers the brain and spinal cord. This can cause TN if the tumor pushes a blood vessel against the trigeminal nerve.
Usually benign tumour of the brain and spinal cord.
A firm, often vascular, tumor arising from the meninges of the brain or spinal cord.
A type of tumor that occurs in the meninges, the membranes that cover and protect the brain and spinal cord. Meningiomas usually grow slowly.
A brain tumor arising from the fibrous tissues that cover the brain's surface and spinal cord.
Meningiomas are the most common benign tumors of the brain (95% of benign tumors). However they can also be malignant. They arise from the arachnoidal cap cells of the meninges and represent about 15% of all primary brain tumors.
