Just to let others know I have emailed Mommy B personally about our Hamish and his tufted angioma - she was kind enough to email me. I have only just read this post tonight!
I have recommended that she get an MRI asap for precautionary reasons as much as anything. I wish this had been done with Hamish back when was first diagnosed. Then they can go from there...I don't recommend wait and see with Tufted angiomas - they grow slowly and infiltrate!
