1 m.0:00
Okay, in this case we have a 71-year-old
0:02
female presenting for a screening mammogram.
0:06
In terms of image quality, I think
0:07
we have good image quality here.
0:09
Um, good amount of pectoralis
0:10
muscle and posterior tissue.
0:12
You see nipple in profile in both views.
0:16
We focus on just the MLO views of this patient.
0:19
Uh, we can see on these SMV that there are a few,
0:23
um, round, uh, calcifications up here in the left.
0:28
Of course, we'd wanna investigate this a little bit
0:30
further and look at prior exams to see if they're new.
0:33
If they are new, we'd wanna make sure we
0:35
look through, uh, try to determine a little
0:37
bit more about morphology if we can.
0:39
Of course, this is screening environment that we
0:41
aren't the highest resolution images that we can
0:43
acquire, but we wanna make sure we evaluate whether
0:45
this is something that we need to call back or not.
0:48
So if we look at just this left MLO view, um.
0:53
You can see our calcifications and
0:54
we'll switch over to the DBT stack.
0:56
Now, one thing we noticed right away is that, uh,
0:58
some of these calcifications or whatever we're
1:00
looking at here, um, shows up in the very first
1:03
imaging stack on the lateral aspect of the breast.
1:05
We can see this is probably related to, uh, skin.
1:08
We see some skin folds and skin findings here.
1:11
We see those subcutaneous, uh, fat deposits.
1:14
Um, and it's just, and the area that we're seeing
1:17
is really in that first slice to scroll through.
1:19
We don't see anything in the breast
1:21
parenchyma, or even as we scroll
1:22
all the way over to the medial side.
1:25
So because it's in the first, uh, few slices
1:28
on this lateral side, we know therefore these
1:30
are, um, calcifications in or on the skin,
1:33
potentially on, since this is the axilla, and
1:36
this is very likely to be, um, some focal, um,
1:39
deodorant artifact or sometimes, uh, some sort of
1:42
sort of artifact we see.
1:44
So because we see it here, uh, even if this is
1:46
new, we really don't need to do anything about it.
1:48
We just call this a normal and benign and.
