One piece of advice for parents raising a child with cavernous angiomas:
"Actually, I have three pieces of advice. One: When going for MRIs, make sure your child isn't wearing a certain brand of underwear that starts with an "H" and ends with an "S." If you get what I mean. A technician warned us they use metallic thread in some of their waistbands. Not sure it makes a difference, but, hey.
The second is don't let them ever bring in a stuffed Pikachu. I have no clue what inside of it is metal, exactly, but something is. This we learned the hard way. It got sucked right into the machine. They weren't happy with us, either.
The third is be patient. With your kid, your spouse, but most of all yourself. Because you're going to screw up. Every parent does." -S, dad of son with multiple cavernomas.
