All right. So what we're going to do today is we're going

0:03

to go through some breast Imaging cases. So our first case is

0:06

a 50 year old presenting for an annual screening mammogram.

0:10

This was her mammogram and I'm just going to

0:13

give you a brief moment to look over it because the next slide is much

0:16

more important for the questions. So here's her mammogram.

0:21

And this is what the image you need to look at. So take

0:24

a look at this. This is the image with the part in

0:27

finding.

0:31

All right. Now we'll look at the question.

0:33

and once you know the answer you can feel free to

0:36

fill in your answers

0:40

so it looks like the majority of people answered eggshell

0:43

calcification and byret

0:46

to

0:47

and that is correct.

0:50

And so these are oil sets. So let's go

0:53

back and look at them. So.

0:55

These are benign finding they are caused by fat and acrosis

0:58

and we have the running calcifications

1:01

that go fully around in 3D to

1:04

represent like an eggshell. So the what happens with oil says is

1:07

they are fat necrosis. And so what happens in

1:10

Santa Cruz, this is traumas to the fat the fat liquefied.

1:14

Think of the liquefies fat as the egg yolk and

1:17

the Egg the center of the egg and then calcifications

1:20

form around it just like an eggshell

1:23

would right. And so that's what you're seeing here. These

1:26

are oils that which are a result of fat necrosis. They're described

1:29

classically by viruses HL calcifications

1:32

and they are virus to benign.
