These tumors develop near the hypothalamus and the pituitary gland. It is a benign tumor and undergoes a slow growth, but as it gets bigger, it would start pressing on neighboring structures and cause several signs and symptoms.

These tumors usually appear in children under 10 years old, but they may also affect adults in some cases. The reason why craniopharyngiomas appear is poorly understood, but it is suggested they start forming as the embryo develops during pregnancy, and results from an abnormal transformation of brain cells, which is called metaplasia. This type of tumor is not very frequent, and the symptoms depend on how the tumor grows and the affected brain areas.
