All right, here we have another case of

0:03

inflammatory bowel disease involving the colon.

0:06

In this case, what we see is clear

0:08

hyperenhancement in the sigmoid colon.

0:10

And you can look at this colon and you can

0:13

compare it to the ascending colon and you

0:15

can see how much more enhancement there is.

0:17

So it's clearly inflamed.

0:19

We also notice that the whole bowel wall is

0:21

enhancing, so there's no sparing of the outer wall.

0:24

Importantly, it looks like the rectum is spared.

0:27

So, with rectal sparing like this, you're

0:30

immediately thinking this should not be

0:31

UC, unless they've had rectal steroids,

0:35

there's no reason why it would

0:36

spare the rectum to that degree.

0:38

And so we're thinking probably

0:40

Crohn's disease in this case.

0:42

We also see that the descending colon looks

0:44

relatively okay, but as we get up here, kind of

0:46

splenic flexure of the colon up into the

0:49

mid transverse, we can again see enhancement.

0:52

So that indicates that there's some sort of skip

0:54

lesion involving the sigmoid colon as well as

0:57

the splenic flexure of the colon with sparing

1:00

of this portion, at least, of the transverse, maybe some

1:03

more involvement here and then sparing of the cecum.

1:06

No small bowel disease interestingly.

1:08

So this would be Crohn's disease with skip

1:11

lesions, but isolated to the colon and not

1:15

ulcerative colitis, which is the important

1:17

differential that they're going to want to exclude.

1:20

Here you can see really nicely how

1:21

you have this lesion here, nothing here

1:25

and down here, and nothing here.

1:27

And so this is Crohn's disease with

1:30

colon involvement and skipped lesions.
