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

0:06

Takayasu's arteritis, and he had one

0:10

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

0:19

lower neck structures here.

0:21

So we're at the aortic arch 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 of the

0:58

blood vessel. As we scroll further superiorly,

1:03

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 is some areas of narrowing and that

1:14

abundance of the intermediate density tissue of the

1:19

Takayasu's inflammation. 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 common carotid artery bilaterally

1:56

in a patient who has Takayasu's arteritis

2:00

affecting the carotid space.
