Hi all.

I would like to ask a question. I have many lesions in my brain, most of them periventricular or in the corpus callosum. A very typical "Dawson's finger" image that could be a perfect example for a book, according to my neuro.

In addition, I have some small lesions in my spinal cord, at the cervical region. Finally, I have 2 very tiny at the level of T4 - T5 that are 100% asymptomatic and have been there for more than 10 years without ever noticing them.

My azygos vein had no stenoses, despite I don't really trust the radiologist that examined me. My lesion load is ABOVE the level of the heart.

Does no azygos involvement mean no lower spinal cord involvement? Where can this be found? I didn't see it clearly in Zamboni's studies. Were there people with juggular stenoses that had lesions in the lower spinal cord?

Thank you all!

I do not think we are proven enough to say 'this' means 'that' we do not know all the ins and outs of it yet...
however using the model that stenoses are causing these then there'd need to be an azygos issue for the spinal area to be impacted because that is the vein that drains that area.

Other questions come to mind, let's say for example you have jugular issues and that is all that Dr Zamboni found and you felt sure your test was well done and well interpreted. are those 10 year old never expanding lesions actually MS lesions or is it possible they could be something else? Is it possible that you could have had a stenosis before that has resolved, and the lesion stopped in its tracks when that happened? I do not know but over time answers to these questions will be clear. There is a lot of research to be done yet.

Also since you don't have a definitive answer yet, what is your plan about that?

Hi.

I am convinced that reflux is the culprit, not stenoses. Stenoses add to the problem as far as they cause reflux.

I am planning to have doplers done to look specifically for reflux. One step at a time. At first, my radiologist and I checked if we could display the veins. We plan to do the actual examination this week, or the next. He is very busy these days and wants to have his time to avoid mistakes.

MRV in the azygos did not show any stenoses, but, like I said, I question the method used. Marie, you had IJV stenoses. Where is your lesion load?

Thank you for your answer!

Dawsons fingers large and periventricular. 4 of them with 2 small barely visible one somewhere else that I do not see myself. All of these are old as the hills. Mine stenoses were bilateral jugs high up in the angle of the jaw. THe pressure across the stenosis was decreased by about 3 points after stent placement and the collateral disappeared. My dopplers were normal......... except for a higher than expected flow in the vertebral veins that should have tipped off the sonographer. My first dopplers done locally did note the VV turbulence or reflux, but noted nothing unusual in the jugs
