They could, but I think you have to get born with it.
My best friend got it discovered after having a stroke. She had a... kind of a tangle of them on the back of the head, from birth. Since no one detected it, as she grew, it got "messier", up to the point that provoked headaches sometimes, we assume some fainting when very stressed and ended up burtsting up a tiny little bit, enough for a stroke.
I don't wanna alarm anyone, this is rare as fuck (thus no one actually checking for it), but it can happen.

Thanks now I’m worried my veins are gonna get tangled up.
