Craniopharyngioma is a common embryonic residual tissue tumor developed from the residual epithelial cells of the craniopharyngeal duct formed by the ectoderm. It is the most common congenital tumor in the brain. It ranks second among sellar tumors. It is more common in children and less common in adults. It is more common in the sella turcica, accounting for 5-7% of all intracranial tumors and 12-13% of intracranial tumors in children. Its main clinical features include hypothalamic-pituitary dysfunction, increased intracranial pressure, visual and visual field disorders, diabetes insipidus, and neurological and psychiatric symptoms. CT scan can confirm the diagnosis. The main treatment is surgical removal of the tumor.
