What Does This MRA Finding Of Posterior Circulation Indicate?
Question: Should I be concerned about my MRA finding of Posterior Circulation: Stenosis of the proximal cervical
nondominant right vertebral artery and distal intradural right
vertebral artery. Left vertebral artery is noted to be dominant. i have already been diagnosed with autonomic neuropathy, small fiber neuropathy, ehlers danlos syndrome, chiari malformation (have had occipital decompression in 2010), and probable CSF leak based on symptoms and MrI. I have a CT myelogram and blood patch scheduled. None of my docs seem too concerned about this but with all of my bizarre symptoms, it seems this could be an issue. There is talk of sending me to a vascular specialist. I am so confused by all of this.

Detailed Answer:
I read your question carefully and I understand your concern.
It seems that there is an asymmetry between your two vertebral arteries. The vertebral arteries supply with blood the posterior part of the brain. It seems the right one is of a small calibre and narrowed in a couple of segments. The good news is that the left one is well developed and compensates for the relative little blood supply coming from the right.
Such variations are common in many people, more so if you have ehlers danlos. The finding on this report doesn't represent any brain lesion, shouldn't cause any symptoms because as I said the left vertebral artery takes charge, that is why your doctors aren't concerned.
As someone with Ehlers Danlos you do have a slightly higher risk than other people for cervical artery dissection or stroke, but there is no indications of that on the MRI.
I remain at your disposal for further questions.
