Willbur, I'm curious as to why you were tested for NF2? You only mention one AN and no other tumors. Most people with an AN don't have NF2, and most people with NF2 have multiple tumors. Even if someone with mosaic NF2 only has one AN, they almost always have other tumors (tho obviously it is possible to find one before the others appear.) Honestly, I think your chances of having NF2 are very, very, small! Hopefully you are reassured by Kathleen's comments and by the fact that, even with one AN, you will have regular follow up MRIs, so your docs will be able to look for any signs of other tumors.
