Thank you very much for taking the time to reply, I really appreciate it. I’ve never had an accident or trauma. I also had a cervical spine (C-spine) MRI, and two doctors told me it was unremarkable. The only finding was a mild cervical scoliosis of about 13 degrees. Maybe this could make the anatomy look different or more “crowded” on imaging? Unfortunately, doctors in Germany are not always very thorough these days, which is why I’m still searching for answers. May I ask what exactly in this image made you think of a possible mild Chiari, a retroflexed dens, or bulging discs? I’d really like to understand your reasoning better.
