Our next case is a 34-year-old

0:03

woman for high-risk screening.

0:05

This was her baseline MRI, and she had

0:08

a history of right breast biopsy and a

0:10

strong family history of breast cancer.

0:13

So to start with, this is the patient's

0:15

MIP, and this is a case we saw earlier

0:18

in this Mastery Series, but I think

0:20

it's a good example of, uh, BI-RADS 3.

0:24

So she has asymmetric background

0:26

parenchymal enhancement, lots of

0:28

enhancement here on the right side,

0:31

less on the left, but the enhancement she

0:34

has on the left is a little bit more focal.

0:36

And

0:39

we're going to pull in her T1 and

0:44

her first post-contrast images.

0:48

So she has heterogeneous

0:52

or extremely fibroglandular tissue.

0:55

She's had a biopsy on the right, so you see the

0:58

susceptibility artifact from her biopsy clip.

1:00

And then you can see all this enhancement

1:03

here, mostly on the right side.

1:10

And in her case, we felt that since this

1:12

was a baseline and the enhancement looked

1:15

like it might be, um, mostly at the edges of

1:19

her tissue, kind of a very typical pattern

1:22

of background parenchymal enhancement,

1:26

we elected to do a six-month follow-up.

1:28

And mostly that was because this

1:29

wasn't symmetric bilaterally.

1:32

And she did have some more focal

1:35

enhancement here on the left.

1:38

So we considered this to be BI-RADS 3, and

1:41

we saw her in six months, at which time the

1:45

enhancement had almost completely resolved.
