As we've seen

0:02

in the slide deck, the

0:04

fibromuscular dysplasia and non-inflammatory vasculopathy, and that's what this

0:08

case is. It's important to assess all the vascular beds.

0:13

Renal arteries are particularly important to look at.

0:16

And when I'm looking at all of my arteries, other than looking at the

0:20

patency, I also really like to look at their

0:24

morphology and contour. So as I'm scrolling down here,

0:28

everything does look patent, but if you notice and focus on just

0:32

your left external iliac artery as you're scrolling, you'll see how

0:35

it has this undulating and irregular and corrugated

0:42

luminal appearance about it. And the same holds true

0:46

for the right side. So if you're scrolling here and you're looking at that right

0:49

side, you can see how it has this knobby, irregular, beady

0:53

appearance, and that classic word is beaded appearance.

0:57

I think the more easy way that should be part of our search

1:01

pattern is really looking at these vessels on a MIP and in a coronal image.

1:05

So if I make a MIP of these images, which is another advantage of

1:09

having these thin slice images,

1:12

you can see here this corrugated, beaded appearance of the external

1:16

iliac artery on the right side as well as on the left side right

1:20

here. And then looking back again,

1:24

there's also some irregularity and beaded appearance of that distal left renal

1:28

artery here.

1:30

This undulating, beaded appearance here.

1:33

And this is a very classic appearance of a

1:36

non-inflammatory vasculopathy.

1:39

The classic example for that is fibromuscular dysplasia,

1:43

which typically involves the renals and the carotids and the vertebral arteries.

1:47

But there are other analogs of fibromuscular dysplasia which can also have this

1:51

appearance.
