0:01

This case, we have a 45-year-old female

0:02

presenting for a screening mammogram. Image

0:07

quality looks appropriate in this case.

0:10

Looking right away, we can tell that

0:11

she has one area of calcifications here.

0:13

Her previous, um, biopsy, uh,

0:16

the upper outer left breast.

0:19

Looking at just the CC views,

0:23

we can see.

0:24

Uh.

0:26

Already there are some focal asymmetries

0:28

or masses probably in both breasts

0:31

as we scroll through the DBT stack.

0:32

We can see these things do look more

0:35

like masses, even though we're only

0:36

looking at them on single view currently.

0:39

We can see at least one here, one here, and one here.

0:44

And I'm sure if we looked further, we'd find

0:46

even more. If we look over on the CC view on

0:49

the left side and we see a similar appearance.

0:53

Several, uh, small masses showing up

0:56

as we scroll through the DBT stack,

0:58

one here.

1:00

This location

1:02

here looks

1:04

like there's probably one coming into being here.

1:06

Uh, and as we scroll through, we can see even

1:08

more of those similar on the, uh, MLO views.

1:14

On this one, again, we can see some corresponding

1:17

areas, uh, that look like they will correspond

1:19

to the masses that we saw on the CC view.

1:22

And as we scroll through those slowly, we can see,

1:24

uh, multiple masses again, uh, come into view.

1:29

This is true on both breasts. Um, as you're aware,

1:34

uh, when we receive multiple bilateral oval

1:37

circumscribed and secure masses, this is benign.

1:42

There's nothing else we need to do here.

1:43

As long as those masses aren't changing, uh, in

1:46

comparison to the prior exam, or one is changing

1:49

and the rest aren't, something like that, um,

1:51

these can, uh, be considered benign. Most likely

1:54

multiple cysts or potentially multiple fibroadenomas.

1:59

And nothing else is needed.

2:01

Now again, to meet that definition,

2:02

you need to have, uh, two masses.

2:04

You need to have at least three masses, and two of

2:06

those have to be on one side and one on the other.

2:09

Um, so sometimes you'll see something where you

2:11

just get two on the one side and never on the other.

2:12

That one wouldn't strictly meet the criteria.

2:14

Again, we need to have two masses on

2:16

one side, at least one on the other.
