1 m.0:00
This is a 43-year-old female presenting,
0:02
uh, for routine screening mammogram.
0:06
We see, uh, heterogeneously dense breast tissue.
0:10
Uh, the image quality is good.
0:12
Pull down images on the right
0:14
breast CC and MLO projection.
0:17
Looking quickly, we don't see anything
0:19
that looks potentially worrisome.
0:24
On the right side, if we look closer and
0:26
really magnify or blow this up, we can see
0:28
some subtle potential calcifications here
0:30
in the lateral aspect of the right breast.
0:34
We don't see, uh, any corresponding
0:36
calcifications, uh, in the posterior
0:39
depth, in the right breast on the MLO view.
0:41
And if we look relatively closely,
0:43
we don't see anything that.
0:49
Stack, we can see these
0:50
calcifications or calcified material.
0:51
Well, there's, looks like it's sort of on the
0:53
inferior aspect of the breast, potentially skin.
0:57
Um, and we don't see anything further as
1:01
we scroll through the entire living stack.
1:05
These calcifications were recalled for
1:06
further evaluation of diagnostic mammogram.
1:10
We performed, uh, magnification views in
1:12
the right breast and the CC projection.
1:14
Again, don't see, uh, those
1:16
calcifications in the right breast.
1:19
And even, uh, if we look in the magnified ML
1:23
view, we again don't see any calcifications
1:26
that correspond to these, uh, areas.
1:29
What this means is these, like calcifications that
1:31
were identified on the screen exam are likely pseudo
1:33
calcifications related to tomosynthesis imaging.
1:37
Um, potentially these ones are close to
1:38
the skin and perhaps that led us astray.
1:40
I think a couple things that, uh, guide us
1:43
in that direction, that these are close to
1:44
the skin and that we really don't see them
1:46
on any of the subsequent DBT, uh, stacks.
1:50
At least not very well.
1:51
The only one we could potentially do is potentially
1:53
here, and maybe that's just a skin finding.
1:56
But anyway, this patient went on to have a
1:58
diagnostic mammogram, which was completely benign
2:00
and negative, and no additional workup was needed.
