As someone who suffers from post-traumatic SM, I have often looked to find more info on how tethered cord is diagnosed from MRI images. If anyone has a good link to something that shows the typical imaging that illustrates TC on an MRI image, I'd be glad to know what it is.
Some argue that any PTSM is likely to have some degree of TC, almost by definition. I think the jury is still out on that, butit does make some sense that an injury will often cause scar tissue to form, frequently leading to TC.
I've yet to be seen by any doctor with the specialization to properly assess my spinal issues. I am being tended to by several people who at least understand that SM is nothing to be dismissed as inconsequential. A recent change in meds has helped me more than anything else in almost a year since my SM diagnosis after decades of seeing docs who were either clueless or who put the interests of others ahead of my health. I'll write more about the med change soon, but I wanted to fully assess the help it's been and the limitations of that help, so that the info is helpful to others.
In general, the central nervous system pain that suffused my spinal cord has been considerably alleviated. I've been able to almost do without the hydrocodone that was messing up my digestive system with constipation, but which provided only partial relief for my CNS pain. The only thing I take it for is when I can't get to sleep at night.
This is caused by my tailbone hurting, as if someone has stepped on it or kicked me right above what would be my plumber's butt, if I wasn't careful to wear a suitable shirt.
This pain would have been a mystery to me if the NL I recently started seeing hadn't pointed out some issues way down at the tail end of my spine. I thought little of it, until the recent med change. Trying to quit the hydrocodone was very easy with the new med, except that I started getting that darn pain down there once I laid down and tried to get to sleep. It's very disconcerting to have a pretty good day, then to try to get to sleep only to have this problem crop up.
The other day, we had a thread that asked people to show some representative MRI images. I posted several, but I'll only repeat two of them here. The first is one that shows where my syrinx is located, centered around T7-8. It extends upwards a couple of vertebrae. Depending on the image, it can extend downward a couple of vertebrae, in some images, or even much further, as in this image:
Then there is the image of the funky tailbone:
The first seems to show my spinal cord "pulled toward the front" of the intraspinal space. The second seems to show my spinal cord "pulled toward the back" of the intraspinal space. It also has a twisted braided look to it. I realize that this is not the spinal cord itself down that low, but the terminal attachment that those who have TC surgery mention as releasing pressure when it is cut to allow their spinal cord to float freely in the intraspinal space.
Does TC show up in images as this "pulling" toward the front or the back of the intraspinal space?
Is the twisted, braided look in the second image, along with the fact that it seems to run along the backside of the intraspinal space another indication of TC?
In both cases, it looks like my spinal cord is trying to take the shortest path between two points, perhaps because of the tension created by TC. Is this how it's diagnosed or am I mistaken?
Finally can anyone direct us to something that shows how TC looks in MRI images, presuming that maybe my images do not show TC?
