Epidemiology

Craniopharyngioma is a common intracranial tumor constituting 6% to 13% of all childhood brain tumors and 1% to 3% of all adult brain tumors.[13] It is the most common sellar region tumor in childhood, and the most common nonglial intracranial tumor.[14] Although it may present at any age, a bimodal age distribution is reported with a peak between 5 and 14 years of age and between 50 and 70 years of age.[12][15][16][17]

Craniopharyngioma is found worldwide. The age-adjusted incidence rate in the US is around 1.7 cases per 1 million person-years.[16] Global incidence rates have been estimated at 1.34 cases per million per year in all ages, and 1.44 cases per million per year among children.[15] There is no sex difference in incidence.[4][17]
