I sent a message to my neurologist through the hospital portal to inform him of these results (testing done at another facility)...he just said "it could be genetic", which I understand can be. I will be seeing him in person next month for my usual check up. I had a concussion in 2019 which kicked off terrible migraines, never had them before and still have them on occasion today, that's why I see him. To my breast oncologist this finding is new information, she is in a different hospital portal system so she has nothing to compare this finding to. I checked back to my old CT scans and brain MRIs, from 2019 to present ordered by my neurologist...it's never on such reports except once in a 2020 MRI/MRA where it actually says "posterior fossa: no tonsil present."
So, it seems to me since 2020 to the present 2026 - at some point - this happened to my brain? A "tonsil" developed in my cerebellum?
Concerning to me and not sure exactly what this means...
Thank you for your thoughts.

I also have chiari, they said mine could also be genetic when I started to get mild headache and neuropathy. Mine was 11.75mm and they seemed to think it was unlikely that it was causing my symptoms. Have you been checked for IIH (Idiopathic Intercranial Hypertension)? Do you have leaking out of a nostril/ear? You may need to request an LP. The concussion could of cause trauma and triggered this. This can cause tonsils to sag as well.
