This was a 54-year-old male who had a history

0:05

of known Takayasu's arteritis,

0:09

and he had one week of increasing chest pain.

0:13

These are the thin section axial

0:15

scans through the neck.

0:17

And I'm going to just point out the lower neck

0:20

structures here. So we're at the aortic arch,

0:24

and if we look at the internal...

0:27

the common carotid artery on the left side,

0:30

what you see is tissue which seems to be surrounding

0:35

the proximal left common carotid artery.

0:39

So normally, the fat around here would be this density,

0:43

the dark signal here.

0:45

And what you're seeing is this kind of grey tissue

0:49

around the proximal left common carotid artery,

0:53

which is the manifestation of the inflammation

0:57

of the blood vessel.

1:00

As we scroll further superiorly,

1:04

you note that the blood vessel has a more normal

1:07

appearance and contour to it rather than down here

1:11

where there are some areas of narrowing,

1:14

and that abundance of the intermediate-density tissue

1:18

of the Takayasu's inflammation.

1:21

Here is the innominate artery,

1:24

and the takeoff of the right common carotid artery.

1:29

And again,

1:30

what should be this dark density fat shows posteriorly

1:37

intermediate density, representing the inflammation

1:40

along the posterior wall of the blood vessel.

1:43

And you can see a little bit of the irregularity

1:45

of the lumen of the blood vessel.

1:47

This patient also has a large thyroid nodule,

1:49

but this is a manifestation of the proximal

1:52

involvement of the common carotid artery bilaterally

1:56

in a patient who has Takayasu's arteritis,

2:00

affecting the carotid space.
