Craniopharyngioma is a rare type of brain tumor that originates from embryonic cells of the pituitary gland and the hypothalamus. The tumor mostly affects children and adolescents and can cause various symptoms such as headaches, vision problems, hormonal imbalances, and cognitive impairment. There are different synonyms that can be used to refer to craniopharyngioma, including Rathke's pouch tumor, adamantinoma of the pituitary gland, and craniopharyngeal duct tumor. Additionally, medical professionals may use terms such as suprasellar tumor, hypothalamic tumor, and infradiaphragmatic intracranial neoplasm to describe craniopharyngioma, depending on its location and its impact on the adjacent tissues and organs.
