Craniopharyngiomas, like chordomas, develop from cells left over from early fetal development. They often grow at the base of the brain, near the brain's pituitary gland (which releases chemicals important for the body's growth and metabolism), and may also affect the optic nerve and surrounding tissue. Craniopharyngiomas usually affect young children and adolescents.
