Wk 1, Case 3 - Review

0:00

So this patient's history of surgery in the

0:04

right breast and, um, screening exam, right?

0:08

So we see this commonly that if you have

0:10

a screening MRI screening program in

0:12

your institution, you might have patients

0:14

coming in for high-risk sort of screening.

0:17

And, um, you know, the first thing, uh, to

0:21

mention here, this one, you always want to look,

0:24

of course, at the, of everything, but, um, but

0:27

things you'll notice in, for surgery, right?

0:29

Um, you might see some distortion

0:31

related to her surgery.

0:33

You might see surgical clips.

0:34

And I think both of those things are,

0:36

um, easily evaluated on the, um, T1

0:41

non-fat set, um, pre-contrast images.

0:44

Um, so, you know, in this case here, right, we

0:47

see the right breast looks a little bit smaller.

0:48

Um, probably has some distortion here.

0:50

It's a little bit hard to tell

0:51

in this case, maybe right here.

0:53

Oops.

0:54

Um, I don't

0:56

See the surgical clips too well here.

1:00

I don't have any big ones.

1:01

Of course, you could always

1:02

verify on our mammogram.

1:03

That'd be a lot easier.

1:04

But, um, so that's stuff for surgical.

1:07

So relatively subtle surgical findings

1:10

here, but we know that history.

1:12

Um, in the left breast,

1:15

we've got two, uh, masses.

1:17

Um, so we will look at her pre here and um,

1:23

we can see some inherent, uh, T1 signal

1:27

in those masses too, um, but what we want

1:30

to look at are the post-contrast images

1:34

here, and we can see one mass here, right

1:36

has very smooth rim enhancement around

1:40

that mass, and the other one is right here.

1:44

Um, same sort of very smooth rim contrast.

1:48

So think about that in distinction

1:50

to the first case we had where

1:53

we had rim enhancement, but it

1:54

was very nodular, very irregular.

1:56

That would be a much more suspicious finding.

1:58

So, um, I think in this case, if we pull up

2:02

the T2, we can see that those are T2 bright.

2:06

This, this one, not as much, but I think

2:09

we can be confident in calling those,

2:11

um, cysts that have some inflammatory,

2:14

inflammatory cysts that have some

2:15

surrounding, um, smooth rim enhancement.

2:19

Relatively straightforward case, but, um,

2:21

but important to be able to confidently

2:24

identify those, those inflammatory cysts.

Report

HISTORY: 44 year old woman with history of treated T2N1 right breast cancer status post lumpectomy, known ataxia telangiectasia-mutated (ATM) gene, and heterogeneously dense breasts presented for high risk screening.

Summary of prior imaging:

Mammography: Breast conserving therapy (BCT) changes right breast, postoperative changes in the right axilla and stable benign appearing 0.9 mass left breast 3:00 middle depth.

Ultrasound: None applicable

Breast MRI: No evidence of malignancy, BCT changes right breast and benign cysts with rim enhancement left breast

FINDINGS

Quality control issues: ☒None ☐Poor/lack contrast bolus ☐Poor fat suppression
☐Susceptibility ☐Movement ☐Other

Background Parenchymal Enhancement: Minimal

Amount of Fibroglandular Tissue: Heterogenous glandular tissue

LEFT BREAST

Narrative
There are two inflammatory cysts in the left breast laterally. There are no suspicious enhancing masses. No axillary or internal mammary lymphadenopathy is seen. There is no abnormal skin or pectoralis muscle enhancement.

Left breast lesion 1

Lesion type: Mass
1.4 cm. Lower outer Quadrant. 3:30 Radian. 4.5 cm from the nipple.

Mass/post-surgical change: Shape:Round. Margins:Circumscribed. Enhancement: Rim.

Lymph nodes LEFT: ☒Normal axilla

RIGHT BREAST

Narrative
The right breast is smaller is size, with architectural distortion in the central breast. Postoperative changes are present in the breast and axilla and the nipple is absent. There are no suspicious enhancing masses. No axillary or internal mammary lymphadenopathy is seen. There is no abnormal skin or pectoralis muscle enhancement.
