Anyone else heard this stat?

I was reading today that 30% of people who go in for unrelated MRI's

show a chiari malformation. They are asymptomatic, but the chiari is

found incidentally. Wow - that means that 30% of people have some sort

of herniation. Actually, probably more, because those are just the

asymptomatic patients. Of course, I know that some patients may

actually be symptomatic and are misdiagnosed - but either way, 30% of

people. Just wondering if anyone else has heard this.
