Hi, Joan:
Jan is right to say we're not doctors and can't diagnose. Having said that, however, I want to alert you to a possible explanation for your MRI results. If you truly have an AN now on each side, your doctor should explore the possibility of neurofibromatosis, or NF-2, an inherited disease. I cannot stress enough that it is way premature to worry about NF-2 or any other possible diagnosis before a specialist sees your films and advises you. But I mention NF-2 so you can mention it to your specialist. If they are not up to speed about NF-2 and you do actually have two ANs (the MRI could look misleading to even some professionals), you should seek out the opinion of an AN specialist who has treated patients with NF-2.
In the meantime, try not to get too wound up over this. It may be a lot less worrisome than you fear.
Best wishes,
Tumbleweed
