Sorry no one has posted anything to help you out here. Just wanted to check in and see if you have had the appointment yet and how it went.
My daughter had a large forehead hemangioma that was removed by Dr. Reinisch. I am afraid I do not know much about ultrasounds or other treatments as we went the surgery route. Just wanted you to know there is support here if you need it
. I found this site incredibly helpful and the people on it amazingly supportive when we were going through all of this with our daughter several years ago.
Hope you have a some good news
