Craniopharyngiomas usually develop near the pituitary gland
A craniopharyngioma usually develops near the pituitary gland at the base of the brain.

A craniopharyngioma is a relatively rare, benign tumor that develops near the pituitary gland at the base of the brain. Craniopharyngiomas occur in both adults and children and affect males and females equally.

Although they’re benign, craniopharyngiomas can behave a bit like malignancies — when they grow they can press on and sometimes invade nearby healthy brain tissue. They can press on the optic nerves and cause problems with vision or invade the hypothalamus and pituitary gland and cause problems with hormones. (see Symptoms of Craniopharyngioma). The tumor can usually be successfully removed surgically, but it sometimes recurs and so patients must be monitored carefully in the years after surgery (see Surgery for a Craniopharyngioma). However, with complete surgical removal, craniopharyngiomas can be cured and the goal of treatment is either cure or lifelong tumor control.

What Causes Craniopharyngiomas?
Researchers don’t know exactly how or why these tumors occur, but they are thought to develop out of cells left over during fetal development — possibly from a structure called the Rathke pouch. There does not seem to be any genetic cause, and the tumors don’t run in families. There is no known way to prevent a craniopharyngioma.
