CLINICAL SCENARIO 6
Ventriculoperitoneal Shunt with New Lethargy
4 topics, 14 min.
0:01
This was a 35-year-old who presented with right
0:04
hemiparesis, and the concern was for a stroke.
0:07
What we saw on the FLAIR scan and the T1
0:11
post-gadolinium scan was a white matter region that
0:16
did not extend all the way to the gray matter.
0:19
It was not wedge-shaped, and it had an
0:21
unusual open ring enhancement pattern.
0:25
This open ring enhancement
0:26
pattern is pretty characteristic
0:29
of tumefactive multiple sclerosis,
0:32
and that's what this patient had.
0:34
So remember that in young patients, new
0:37
neurologic deficits may be a manifestation of
0:41
demyelinating disorders, and I refer you to my
0:44
previous mastery course on white matter disease.
0:49
Here is another patient who had what was
0:52
thought to be a TIA, a new neurologic deficit.
0:55
Same age, 35 years of age, and look at this patient.
0:59
New diagnosis: multiple white matter regions that
1:03
are in the periventricular, as well as in the
1:06
subcortical regions, as well as in the posterior
1:09
fossa, some of which showed gadolinium enhancement,
1:14
and some of which did not show contrast enhancement.
1:19
We have now defined the McDonald
1:21
criteria for multiple sclerosis.
1:24
Lesions that are disseminated in space.
1:27
We have three out of four locations:
1:30
periventricular, subcortical, and posterior fossa,
1:33
the fourth being the spine.
1:35
And we have dissemination in time by virtue of the
1:39
fact that we have some of the demyelinating lesions
1:43
that are enhancing and some up here in the frontal
1:46
region, which are not showing contrast enhancement.
1:49
So, fulfillment of McDonald
1:51
criteria for multiple sclerosis.
