Craniopharyngioma is a rare type of noncancerous (benign) brain tumor.
Craniopharyngioma begins near the brain's pituitary gland, which secretes hormones that control many body functions. As a craniopharyngioma slowly grows, it can affect the function of the pituitary gland and other nearby structures in the brain.
Craniopharyngioma can occur at any age, but it occurs most often in children and older adults.
