Hi @tkeys, I'm tagging @badnaples @smilton and @hyeary into this discussion who may have some tips and experiences to share with you. You may also be interested in this related discussion:

I'm sure it is disconcerting to have made this discovery in your medical records. I'm glad you are being referred to a neurologist to get your questions answered and a plan. Mayo Clinic offers a lot of information about brain aneurysms here: https://www.mayoclinic.org/diseases-conditions/brain-aneurysm/symptoms-causes/syc-20361483

It also includes a list of questions to ask your neurologist like:
- What do you know about the size, location and overall appearance of the aneurysm?
- Do the imaging test results provide evidence of how likely it is to rupture?
- What treatment do you recommend at this time? What are the risks of treatment?
- If I wait, how often will I need to have follow-up tests?
- What steps can I take to lower the risk of an aneurysm rupturing?

I also like your question about "how fast does it grow?"

You might appreciate this video from one of my fav neuro surgeons at Mayo Clinic, Dr. Bendok.
