This was a 62-year-old gentleman who presented with
0:04
a left hemiparesis, and a study was
0:10
done to evaluate for a stroke.
0:13
So this included the CTA as well as a non-contrast
0:17
CT scan. Let me show you the CTA.
0:20
So here we are looking at the aorta,
0:25
the superior vessels, and for this case,
0:27
since it's a left hemiparesis,
0:30
we'll concentrate on the right side.
0:32
So here's our right common carotid artery leading to the right
0:36
internal carotid artery. It's a little bit tortuous.
0:39
We're just following the right common carotid
0:43
artery. The carotid sheath looks good.
0:45
Here's the jugular vein, which is not opacified.
0:48
So good technique showing just the arterial system.
0:51
And as we follow the right internal carotid artery,
0:56
we come into this contrast-enhancing mass which is
1:01
medial to the right internal carotid artery.
1:05
However,
1:06
you can see that it becomes part and parcel of the
1:10
right internal carotid artery as we
1:13
come to the angle of the mandible.
1:15
So this is indeed a pseudoaneurysm of the right
1:21
internal carotid artery. Extremely large.
1:25
Notice that it's in the prestyloid region of the
1:30
carotid space and it extends to the skull base.
1:36
So this accounted for the patient's source of an
1:41
embolus which led intracranially. Let's continue.
1:45
I'm going to change the window
1:46
here to look at the brain.
1:48
So now we're looking at the brain
1:50
parenchyma at the cerebellum.
1:53
And as you can see, as we come up further superiorly,
1:56
there's a difference in the density of the right
1:59
hemisphere compared to the left hemisphere with
2:03
absence of good middle cerebral
2:05
artery branching pattern.
2:07
Here's the Sylvian fissure, normal vessels in the
2:10
left Sylvian fissure, absence of vessels
2:13
in the right Sylvian fissure.
2:15
This is all infarcted brain tissue within the
2:19
right middle cerebral artery distribution.
2:22
The anterior cerebral arteries you
2:23
actually see not bad over here,
2:26
but you can see that there is diminished caliber to
2:30
the right supraclinoid and cavernous carotid artery
2:34
and then a clot within the middle cerebral artery.
2:38
So this is an example of a patient who had
2:43
a stroke associated with a right internal carotid
2:47
artery pseudoaneurysm extending into the middle
2:49
cerebral artery and leading to the frontal,
2:53
temporal, and parietal lobes.
