Craniopharyngioma is a benign congenital tumor arising from the participating tissues of the craniopharyngeal canal during embryonic life, also known as enamel cell tumor or enameloblastoma or suprasellar epithelioid cyst. Most craniopharyngiomas grow intermittently, so overall the growth of the tumor is slow and the development of early symptoms of craniopharyngioma is also slow, while a few craniopharyngiomas grow rapidly and their disease progresses faster. Early symptoms of craniopharyngioma: 1) high cranial pressure caused by tumor occupying effect and obstruction of interventricular foramen; 2) visual impairment caused by tumor compression of optic cross and optic nerve; 3) hypothalamic-pituitary dysfunction caused by tumor compression of hypothalamus and pituitary gland; 4) neurological and psychiatric symptoms caused by tumor invasion and other brain tissues. Craniopharyngioma should be considered and examined in the following cases: 1. Patients of any age with high cranial pressure, neuro-ophthalmologic symptoms and hypothalamic-pituitary dysfunction should consider the possibility of craniopharyngioma. It is not difficult to diagnose craniopharyngioma according to the prevalent site, clinical manifestation and auxiliary examination. 2.The early symptoms of craniopharyngioma in adolescent children are endocrine dysfunction, such as short growth, polyuria, obesity, genital dysplasia, etc. This disease should be considered first. 3.Adult craniopharyngioma with early symptoms of sexual dysfunction or headache and visual field disorder should also be considered. The diagnosis is not easy for a few people with atypical clinical manifestations and mild clinical symptoms, and it is crucial to raise the vigilance to this disease.
