Daughters Large AVM in motor strip

My soon to be 16 year old daughter as an unbleed AVM in her left frontoparietal region, mostly centered in the postcentral sulcus, so close to her motor strup. It measures 1.9 x 2.8 x 4.0.

Does anyone have experience or advice they could share on this? We will be meeting with her Dr in a couple of weeks to go over her tests, and want to be prepared. I’ve seen a some info on Linac radiation instead of Gamma Knife for larger AVM, so I’m especially interested in any advice or warnings about that.

Just did a search on linac radiation for you…
