UPDATE: February 8, 2017
Today my wife and I went to Keck Medical Center of USC to be advised of the results my my wife's second MRI, the first being done six months ago. We were told the AN has remained the same and not grown, so, the next step is to schedule yearly MRI's to keep an eye on it. If any dizziness, numbness or facial tics appear we are to immediately contact Keck to take the necessary steps.
So, we are thanking God and all Good People at this time. I will keep this thread updated as time moves along.
