What is a craniopharyngioma?
A person with a craniopharyngioma has a benign brain tumor at the base of the brain. Benign tumors can interfere with body functions, but do not spread to distant areas of the body. A benign brain tumor can cause symptoms by placing pressure against parts of the brain, and by increasing pressure inside the skull. Craniopharyngiomas arise from cells left over during development of a fetus. They start to grow near the pituitary gland and the nerves that send signals from the eye to the brain. Craniopharyngiomas are rare and occur most commonly in children. The exact cause of craniopharyngioma is unknown.
