I just the results of an MRI and it says that, among other things, I have an 8mm Hemangioma at the T12 vertebral body and also a 7mm hemangioma at T11 vertebral body. What exactly does this mean and how is it treated? I already know that I have to have cervical and thoracic surgeries for other things?
