- A -
A glioma that arises most frequently in the cerebrum of adults. Arises in the brain stem, cerebrum, and cerebellum of children. Astrocytomas can be classified as low-grade well-differentiated, anaplastic, pilocytic, and glioblastoma multiforme.
- B -
Occurs in the lowest portion of brain.
- C -
Spinal cord tumor that develops from remnants of early fetal spine-like structure, which is later replaced by the spinal cord.
Occurs near hypothalamus, in the pituitary gland region. Usually benign, but can be considered malignant because of potential damage to the hypothalamus from pressure, affecting vital functions.
- E -
Commonly develops in the lining of the ventricles; can also develop in spinal cord.
- G -
Occurs in the brain or spinal cord.
Arises from developing sex cells.
Germ cell tumor
Also called grade 4 astrocytoma; originates in glial cells.
- H -
Arises from blood vessels of the brain and spinal cord.
- M -
Usually develops in the cerebellum, but may occur in other areas as well.
Develops in the medulla and can spread to the spine or to other parts of the body.
Comprised of oligodendrocytes and astrocytes; originates in glial cells.
- O -
Usually arises in the cerebrum; fewer than 10% are malignant.
Occurs on or near the nerves that travel between the eye and brain vision centers.
Optic nerve glioma
- P -
Occurs in the pineal gland region.
Pineal region tumor
Occurs in the pituitary gland, generally arising in adenohypophysis.
- S -
May originate from a peripheral or sympathetic nerve, or from various cranial nerves, particularly the eighth nerve.
