Breast Circumscribed Mass - Simple cyst

0:00

Okay, these are images from another baseline screening mammogram. We'll

0:04

see that this is really a theme of BI RADS 3 is that

0:08

we're really wanting BI RADS 3 to almost always be on baseline exams.

0:14

This is a 44 year old woman coming in for her first baseline screening

0:18

mammogram. And we saw this mass in the upper outer

0:24

right breast. When the patient comes back for additional imaging, we start

0:30

with spot compression views to better evaluate that

0:36

finding. So here's the CC spot view. This is the C view. And

0:40

again, we see this finding. It's in the upper breast. Let me just

0:45

show you the tomo here. We see this is on the CC view,

0:53

but it looks like a circumscribed mass. It's a single mass. She doesn't

0:57

have multiple masses in both breasts. And on the MLO view, we see

1:04

the finding here. And we scroll through it on the tomosynthesis slices,

1:10

which really gives us a much better view of the margin.

1:16

We see here, this is an oval mass with circumscribed

1:22

margins. We would then recommend doing an ultrasound. If we did not have

1:27

an ultrasound correlate for this finding, this would be the third indication

1:31

for a BI RADS 3 on mammogram. And that's a oval circumscribed mass

1:36

on a baseline exam. However, we always wanna do a targeted ultrasound to

1:41

see if we can, instead of giving this a BI RADS 3 and

1:44

having that patient come back for those follow up exams at six months,

1:49

12 months and 24 months, if instead we can clear this patient and

1:53

say that actually this is a benign finding.

1:56

In this case, we did a targeted ultrasound. We see this in the

2:01

right breast, 11 o'clock position, five centimeters from the nipple. So

2:05

that matches the location of this finding in the upper outer right breast

2:09

that we saw on mammogram. And here we see this simple cyst.

2:14

So that oval circumscribed mass on mammogram may have met criteria for a

2:20

BI RADS 3, but we know that since it correlates to this benign finding on

2:23

ultrasound, we can give this a BI RADS 2, instead.
