Hello my Saviors :0 :)

Hello, I am a 27-year-old man living in Korea. My symptoms began in 2016 after a whiplash injury, starting with increased intraocular pressure in my left eye, accompanied by a sensation in my neck like sand grinding. At first, it was only elevated eye pressure, but from 2017 I started experiencing symptoms similar to Horner’s syndrome — when reading letters, my eye would tremble, I felt confused, and diplopia (double vision) appeared as well. Since 2017, I’ve also had a symptom where my head feels like it is shaking, which I attributed to high blood pressure.

In 2018, I underwent CTA and MRA scans, but both my doctor and a radiologist found nothing. I gave up and tried to endure the symptoms, but eventually my physical strength declined.

In April 2024, while pressing around the C1–C2 area myself, I suddenly developed breathing difficulty and had to call an ambulance. At a large hospital emergency room, I asked them to focus on my neck, but because of pain near my scapula, they only suspected aortic dissection and did not scan my neck. Since then, my condition has worsened significantly.

After researching, I realized they had not scanned the veins, so I initially suspected Bow Hunter’s syndrome, but later realized that wasn’t the case and felt hopeless. Soon afterward, I learned about Eagle syndrome and jugular vein compression, and last month I underwent CTA and CTV simultaneously.

An ENT doctor told me there was no abnormality, but I think I can see signs of venous compression myself. I also have atrial fibrillation, and when I bend my head downward, it feels like it places a burden on my heart. The symptoms similar to Horner’s syndrome have disappeared, but the diplopia still remains. In the early stages, I also experienced dizziness when turning my head, but that symptom has since resolved.

I don’t know whether my left-sided torticollis is the cause or the result, but it seems that the left C1 is larger and angled more downward. The styloid process is not particularly elongated, but perhaps because of the torticollis, the angle looks problematic.

Last week, an ENT doctor performed a palpation. The right side was fine, but the left side was quite painful, and it is still painful now. and fully feeling my vein compression!
i need instant surgery whatever removal styloid process or c1 lateral mass shaving or both!
What do you think? Thank you for reading.

@NoneElongatedStyloid I can help you better assess whether your styloids are compression your IJVs. Can you go to the original CT imagine, go to the axial view, and go to C1? I’ve attached my own imaging to help you know what to look for. Once you upload the photo I can help.

Thank you tml
Is this ok?

@NoneElongatedStyloid maybe one or two slices higher (towards the head)!

I have no computer now so it will be late

@NoneElongatedStyloid from what I see in the current axial slice is that your right styloid (left side of image) is a fairly healthy distance from your right IJV. And your right IJV doesn’t appear compressed against C1 so that’s good.

Your left side (right side of image) is your more problematic side. Your left styloid is more prominent (thicker) than your right styloid at this level. You can see that your left styloid is in contact with your left IJV, and your left IJV is squishing against your left ICA. The reason why a couple slices higher up will be helpful is that I want to see the left side of your C1 transverse process to fill out more, so I can see how much it’s contributing to the left IJV compression. Hope this helps!

@NoneElongatedStyloid - Based on your symptoms & what @TML has said about what he sees in the image you sent, it seems you may have symptoms of both IJV & ICA compression. The fact you had Horner’s Syndrome symptoms, even though it was a while ago, can suggest you have carotid compression as that can cause Horner’s. Other symptoms like higher than normal ocular pressure can be more related to IJV compression. Your styloids are very thick the left one looks pointed & the right one is angled more steeply inward, so even though they aren’t long, they could still be causing symptoms.

I agree that there’s some IJV compression left side (that can cause raised intracranial pressure & sometimes be enough to put pressure on the optic nerve, some members have had visual issues from this), your styloids are thick & the C1 processes look quite long. Also if you can find the images that @TML has asked for, it would be interesting to look at your hyoid bone too, from some of the images it does look as if the greater horns of the hyoid are pretty long & chunky, which can cause some issues too, but the images don’t show enough to tell for sure…

Thank you Jules, it doesn’t seem like there are any blood vessels compressing the hyoid bone




thank you tml what about this

thank you Isaiah i want a surgery very bad

@NoneElongatedStyloid ser attached your hyoid bone annotated image. I labeled your right side (left side of image), so just mirror it on your left. On your right side, your right greater horn is in direct contact with your right ECA and right ICA, immediately above where they come together to form the carotid sinus. Your left side is nearly the same, but there is some space. Swallowing with your head turned, turning you head in certain positions, yawning, or anything that can cause the horns to shift dramatically can put pressure on your carotid sinus areas. Pain from the friction or rubbing can radiate up and down the lengths of the ICA and ECA. You might feel this in your chest, arms, and jawline.

The time when you pressed against the side of your neck and couldn’t breath, it was probably a blood pressure drop due to putting pressure on your greater horn and carotid sinus area causing a vasovagal response. If you ever feel weak all if a sudden, feint/disorientated/dizzy and have breathing difficulties it could be a vasovagal response. Vagus nerve compression (e.g., from styloid/C1) can also cause vasovagal issues, but the carotid sinuses are particularly sensitive.

I know all of this because I am getting my greater horn removed for this reason. I’m a thinner person too, which can cause exaggerated vasovagal responses. I would refrain putting pressure on the sides of your neck because all you’re doing is pushing your carotids against your greater horns. I had the same emergency episode as you did.

@NoneElongatedStyloid can you get a frame or two higher where the wing of your C1 is fully filled out? I circled the area that needs to be bone.

Just something else to note, I might be wrong though- your mastoid bone looks very different one side compared to the other:

The left side (right in image) looks air filled as it should be, but not on the right side? I don’t know if you’ve had any ear issues or mastoiditis? Might be nothing & perhaps normal, I don’t know much about it but was wondering?

Interesting observation, @Jules ! I didn’t know that about the mastoid. Thank you for teaching me something new today. :blush:

Very interesting about the mastoid piece.

I went back to @NoneElongatedStyloid ‘s 3D models, and it does look like his left mastoid is significantly larger than his right. I haven’t seen this before and I do wonder what symptoms it could be contributing to if any.

You also have a curved neck (convex to left) and I wonder if this has to do with how you were laying, or if there could be some cervical scoliosis happening here or if it’s within normal limits.

The inequity of the mastoid processes is even visible in the axial image @Jules commented on.
