I’ve been reviewing my CT scans from 2017 because, while I never ended up getting surgery because my ear pain subsided, my vascular symptoms have been increasing since then. Brain fog, headaches, and primarily a heavy or swimmy sensation, especially in the first half of the day.
Unfortunately, since I don’t know the timing of the contrast flow, I don’t know if I’m looking at arteries or veins. Still, I wanted to ask the opinion of the fine forumers here. (I know…we always say “I’m not a doctor”…so I’ll take it with a grain of salt, haha!)
This is a front view showing the styloid processes and vessels.
In this top-down image, it looks like a large vessel is “squished” between the right styloid process and vertebrae C1. I don’t know if this is a normal amount of squishing.
This bottom-up image shows the same thing. What’s interesting is that while there is a smaller vessel on each side (lime green line), there doesn’t appear to be a match for the large vessel (blue line). Is it so pinched on the left side that contrast can’t flow through it, or is this just an extreme example of single-side vessel dominance?
This is a thin-slice, bottom-up image. It shows the flattened shape of the large vessel (blue dot) on the right side and the absence of a matching vessel on the left side. (In other slices, the vessel is round. It only flattens when between the SP and C1.) The two smaller vessels are indicated with lime green dots.
