I cannot comment on brain MRI, unless you had lesions, then it could be MS possibly. But you need Dr Corenman to talk to you about that. I know very little.

Good luck!!

I would guess that your C6 and C7 are the problem, There is extrinsic compression of the spinal cord centrally and in the subarticular area, your MRI says. From what I have googled this can cause compression of the Vertebral artery
It could be a tumour pressing on the artery or some other neighboring space‐occupying lesion, or a disc prolapse.
I’m sure Dr Corenman will tell me whether I’m right or wrong when he comes on, and he will let you know what is wrong, and advise what to do.

I’m just pointing you in the right direction hopefully?

Copy and paste this link into your browser, it explains Bowhunters.

Sorry to hear you are going through this, I have had similar over past 20 years. Neck CAN cause loss of balance if you search this: https://www.gmjournal.co.uk/cervical-spondylosis-a-cause-of-dizziness
it is great article telling you how it does this.

Bowhunters syndrome is another thing Dr Corenman told me about, so look that up on net too, neck can be trapping Vertebral arteries on turning of your head.

Upright mri scanners are lower quality and can sometimes give false readings, the proper mri is best for quality of images. but if like me you are needing scans in certain positions then Transcranial CAT scan is best, it will pick up vascular problems, i.e. blocked/trapping arteries, blood flow etc. they put a contrast/dye in your vein to highlight anything wrong like a blockage
