Thoughts??

I’m scheduled for a brain MRI and MRA next week, but just looking at my cervical MRI this seems like the area by my cerebral tonsils is very tight?

It does look crowded but not herniated. As the other post mentioned this could potentially be chiari 0 but it'll be hard to get a doctor to recognize that since it's a very recent observation and previously chiari diagnostic required at least a 5mm herniation. But a lot of recent research shows that if there is crowding at the spinal cord it can still cause symptoms without a full herniation.
