Well, I said that I lied to you twice early on
0:03
in this presentation, but actually,
0:06
now I'm going to tell you I've lied to you three times.
0:08
Here is an example of a patient who has
0:11
degenerative disease at the C3 and C4 level.
0:19
And you can see that there is severe spinal
0:23
stenosis at C3-C4 and C4-C5, associated with a
0:28
focal area of cord signal abnormality
0:31
opposite the C4-C5 level.
0:34
Now, I told you that the CSF space will expand when you
0:39
have cord atrophy. Well, that's true in general.
0:45
However, if you have spinal stenosis,
0:49
you notice that the canal gets narrowed
0:54
and therefore you will not see the
0:56
CSF expansion when you have spinal stenosis.
1:02
Here's the axial scan.
1:04
You note that the culprit here is something called
1:08
OPLL, Ossification of the Posterior Longitudinal Ligament,
1:11
which is compressing the spinal cord,
1:13
which has abnormal cord signal.
1:20
However, we don't have expansion of the CSF space
1:23
around the narrowed canal because it's narrowed
1:27
and there is no location or place for the CSF to expand to.
1:33
So this is an example again of spondylomyelopathy
1:37
injury to the spinal cord due to spondylosis
1:40
degenerative disease, associated with cord atrophy,
1:44
but no expansion of the CSF space
1:47
because of that spinal stenosis,
1:50
which is demonstrated quite nicely
1:53
at the C3-C4 and C4-C5 level.
