Our next patient is a 54-year-old woman
0:03
with a palpable lump in the left breast.
0:06
So here are the images for our patient.
0:09
We have CC views bilaterally on the top of the
0:12
screen and MLO views on the bottom of the screen.
0:16
And there's a triangular skin marker in the
0:19
left upper outer breast, and you can see it here.
0:22
You can see this oval mass underlying
0:25
the triangular skin marker.
0:28
So we'll take a look at those images closer up.
0:33
So here's our left CC view and then our
0:39
tomosynthesis images of the left CC view.
0:43
Just scrolling through, we can see that
0:46
triangular skin marker here in the lateral breast.
0:49
And then we've got an
0:51
oval mass, but it has microloupulated
0:55
margins, maybe even a little
0:56
irregular in terms of its margins.
0:58
I'm not seeing anything else in
1:00
this breast except that mass.
1:04
And then, uh, looking at the MLO view, we see the
1:09
mass again, but we also see, um, a prominent lymph node
1:13
kind of sticking out of the corner here.
1:16
So we want to keep that in mind as we're
1:18
scrolling through our tomosynthesis images.
1:21
So here's our tomosynthesis, uh, stack.
1:26
We can see that prominent lymph node here
1:28
in the axilla and then, um, this oval mass
1:32
corresponding to the area of palpable concern.
1:35
And nothing else really
1:37
prominent in that, uh, breast.
1:41
And of course, we're looking at, uh, both sides.
1:45
So we want to make sure that we look carefully
1:49
at the other side as well and not fall
1:53
victim to the satisfaction of search error
1:57
because sometimes there may be something
1:59
else that we need to pay attention to.
2:02
So this is the right CC that I'm scrolling through,
2:04
and then we'll go to the right MLO (mediolateral oblique) view
2:14
and we'll look through that one as well.
2:17
So normal-looking tissue.
2:21
And some normal lymph nodes up here in
2:23
the axilla, but nothing surprising there.
2:27
So our next step for this patient is
0:29
going to be to look with ultrasound.
0:32
And here's our ultrasound, uh, for our patient.
0:36
So we're looking at the area
0:37
of palpable concern first.
0:39
And it's at the 1 o'clock position,
0:41
15 centimeters from the nipple.
0:44
And we have this heterogeneous hypoechoic
0:49
mass with those sort of lobulated borders,
0:53
irregular borders, and it's pretty large,
0:57
2.8 centimeters here,
1:00
2.7 centimeters in the other
1:02
direction, some internal vascularity.
1:09
And then, of course, we went to the axilla as
1:11
well because we had that prominent lymph node.
1:15
So here's the lymph node that
1:16
we were seeing on the mammogram
1:18
2.4 centimeters.
1:19
63 00:01:23,140 --> 00:01:25,380 And you can see here, this is a nice
1:25
example of effacement of the fatty hylum.
1:28
So you can see this echogenic.
1:30
Hilum, but it's very much off-center.
1:34
Part of the cortex is thin, but
1:36
the rest of it is very thick.
1:40
And this is an abnormal lymph node.
1:42
So the cortex is up to 1.
1:45
2 centimeters in thickness.
1:47
And normal cortex, we start being concerned
1:51
about a cortex at about 3 millimeters in a
1:54
patient with a suspicious mass in the breast.
1:56
So at 12 millimeters, this is really.
4:00
Abnormal.
4:01
So, our final BI-RADS category for this patient
4:06
was BI-RADS 5, highly suggestive of malignancy.
4:10
We recommended biopsy of both the mass in
4:13
the left breast and the axillary lymph node.
4:17
The mass in the breast was a poorly differentiated
4:19
invasive ductal carcinoma, and there was a
4:23
metastatic disease found in that lymph node.
