Hi AlliKC .....
As the others have said, you need to take a deep breath and stop reading all of the "what ifs" ..... OK, I will have to be honest, I had my own moment of panic, as well.
Truthfully, until you have that MRI with contrast for a definitive diagnosis (and insist on it when you go to the doctor this week), reading more right now will only increase your fear.
Regarding hearing loss in both ears and the possibility of ANs on both sides ..... that is very rare indeed. There is a condition called Neurofibromatosis Type 2 (NF2), that is normally an inherited condition, in which patients can have bilateral ANs. However, only around 5% of people with ANs are NF2. Since ANs occur in only 1 or 2 per 100,000, 5% of those is a very, very tiny number.
Praying for peace for you until you have the MRI and have some answers. Be sure to let us know.
