Why craniopharyngioma in childhood?

?why not in adult? From the ? I assume you wonder why it shows up in kids.Early rapid infant growth slows to a 5lb & 2-3 in /yr rate in the late toddler years. Over time this slow growing tumor slows the output of growth factors & other agents leading to symptoms like short stature, easy dehydration, vision changes, etc. Leading to dx. Puberty would not progress as expected in with this tumor in place.
