What medical term starts with Ch or K and is followed by Malformation?

Chiari malformation sounds like it might be what you’re looking for.

Thanks @CWOTUS.

There is also Budd-Chiari syndrome, but it’s not a “malformation” and it’s not in the brain.

@flo Are you thinking of an AV malformation? A is for arterial. V is for venous.

@Lightlyseared Thank you.

@Rarebear I’m sorry I just got distracted by the 2 not s in your post, thank you too.
@si3tech ?

@flo Granted my answer was awkward, but does it make sense?

@Rarebear Yes, that’s why I thanked you. It’s good to know that something (completely unrelated?) is named that.
