Next, I'd like to talk about
0:01
two inflammatory conditions.
0:04
The first is Takayasu's Arteritis.
0:05
It's seen in young women,
0:07
particularly Asian females under 30.
0:10
It's an idiopathic inflammatory disease
0:12
involving the aortic arch and branches.
0:15
Patients present with neck pain.
0:18
and strokes.
0:19
They usually have constitutional syndromes such
0:21
as fatigue, malaise, and fever, and the patients
0:26
have smooth concentric wall thickening of their
0:29
proximal, carotid, and vertebral arteries, and
0:31
not infrequently have occlusion in strokes.
0:34
Here's an example.
0:35
These are images of a 19-year-old female who
0:38
had right facial droop and hemiplegia, and you
0:40
can see a pointed, occluded appearance of the
0:43
left common and right common carotid arteries.
0:47
And on the left, she threw an embolus
0:49
to her left MCA, seen here on this MIP.
0:52
And she had a left MCA stroke
0:55
involving the left lentiform nucleus.
0:57
On the axial images, you can see non
0:59
opacification of the internal carotid arteries.
1:01
They're not opacified.
1:02
Um, there's obviously normal pacification of
1:05
the jugular veins and of the vertebral arteries.
1:09
And this is another case of Takayasu's,
1:13
and you can see basically all the major,
1:15
um, vessels from the arch, the proximal
1:18
subclavian artery, the parietal artery,
1:19
brachycephalic artery, the common carotid artery
1:22
are all occluded and there are collaterals.
1:25
which basically supply
1:28
the vessels more distally.
1:30
Here's the MRA and you can see
1:31
the left vertebral artery and the
1:32
right vertebral artery are patent.
1:35
The bilateral internal carotid arteries are
1:37
patent and the circle of Willis looks normal.
1:40
And again, all the major vessels
1:42
coming off the arch are occluded and
1:44
there's a network of collaterals.
1:48
collateralization, she only has these tiny.
1:51
intracranial strokes that you
1:52
can see on this flare image.
1:56
This is a vessel wall imaging where you have
1:59
smooth enhancement in the vessel wall, um, which
2:02
is typically seen with inflammatory diseases.
2:06
And then carotidynia or TIPIC syndrome,
2:09
which stands for transient perivascular
2:11
inflammation of the carotid artery,
2:13
is another inflammatory condition.
2:16
The patients present with unilateral
2:18
neck pain near the carotid bulb.
2:19
They frequently have a history of migraines.
2:22
They'll have elevated inflammatory
2:24
markers, such as a sed rate and CRP.
2:27
And on imaging, what you see is eccentric
2:31
thickening of the carotid wall and
2:33
the perivascular tissues and stools.
2:36
fat stranding.
2:38
Resolves with nonsteroidals and steroids.
2:42
So this is a patient who had neck pain and you
2:45
can see there's abnormality in the carotid bulb.
2:48
It should be filled out, but
2:50
there's a convexity there.
2:52
And when you look at the axial images,
2:53
you can see this inflammatory tissue
2:56
along the posterior wall of the.
2:59
Proximal internal carotid artery
3:01
and also there's fat stranding.
3:03
Um, on the right you can see all this normal fat
3:05
around the vessels, but on the left there's this
3:06
fat stranding and you can see it as you go up.
3:09
Uh, one more cut, more superiorly again,
3:13
stranding surrounding the proximal internal
3:15
carotid artery that you don't see on the right.
3:18
So that's TIPIC syndrome.
