A craniopharyngioma is a rare type of brain tumor derived from pituitary gland embryonic tissue[1] that occurs most commonly in children, but also affects adults. It may present at any age, even in the prenatal and neonatal periods, but peak incidence rates are childhood-onset at 5–14 years and adult-onset at 50–74 years.[2] People may present with bitemporal inferior quadrantanopia leading to bitemporal hemianopsia, as the tumor may compress the optic chiasm. It has a point prevalence around two per 1,000,000.[3] Craniopharyngiomas are distinct from Rathke's cleft tumours and intrasellar arachnoid cysts.[4]
