Why is pituitary adenoma infratentorial in adult tumors but craniopharyngioma is supratentorial in childhood?

Sella Turcica: The tentorium cerebelli separates the cerebellum from the cerebrum. Supratentorial means ABOVE the tentorium and Infratentorial means BELOW.

Craniopharyngioma and pituitary adenoma grow SUPRATENTORIALLY in almost all cases, but rarely invade the clivus into the posterior fossa. ...Read more
