I'm 42 and have a large arachnoid cyst located in the left posterior fossa (bottom left). My cyst was found incidentally during an MRI for something else when I was 27. I never knew I had it. I don't seem to have any real symptoms despite the size. I've been hit in the head during childhood sports, even passed out and hit my head a few years ago, and there were no changes, the cyst stayed as-is.
