Okay case number three. So 71 year
0:04
old female presenting for annual screening mammogram.
0:08
so this is her mammogram in 2016,
0:11
and it's
0:14
kind of a subtle finding so I'm going to draw your attention
0:17
to it, but
0:20
It's in the right upper breath. So you really
0:23
see it up here. This is here from 2010
0:26
you something in between that is from
0:29
2012?
0:31
So you can see that.
0:35
Well, let's see what you see. So the Salient finding so
0:38
we see it on one View and it's been
0:42
kind of growing or becoming more conspicuous over
0:45
time.
0:48
So would that be an evolving asymmetry focal asymmetry
0:51
mass, or architectural distortion?
0:54
Good good, so, I'm
0:57
glad somebody got this wrong because you guys were doing too well
1:00
and you didn't even need to lecture. But yeah, so in a
1:03
symmetry is something that you're gonna see on one of you and it's
1:06
not a math a mass has convex borders.
1:09
So if we go back to just look at that that lesion
1:12
you could see we only saw it
1:15
on the we really didn't know where it was on the CC view.
1:18
We saw it in the right ever breast.
1:20
And you can't really call it mask because
1:23
the mass you have to see on two views and you can't really call a focal
1:26
asymmetry also because you have to see that on two views so really it
1:29
meets the criteria for developing a symmetry like we
1:33
said, so the appropriate buyer ads.
1:37
here
1:40
good. Yeah, so developing asymmetries are
1:43
suspicious and you would want to call her back
1:46
to kind of work that
1:49
up further, you know by red one is negative. So
1:52
it certainly not negative Pirates 2 is benign thyroids 3
1:56
is probably benign you really can't give that office screener. There are
1:59
certain circumstances where you can but this is not one of them. So
2:02
in terms of what you want to bring the
2:05
patient back for all we really know is that there is an
2:08
asymmetry. We know it's in the upper breast.
2:10
Um, I like to do tomosynthesis, I mean
2:13
you could do this by compression as well. But really we
2:16
don't know where it is except that it's in the upper breasts and it's
2:19
really small. So if we need to kind of know what quadrant is
2:22
in so it's almost emphasis is going to give that a set location
2:25
information that's going to be really helpful to determine, you
2:28
know, where it is in the breast. Can we buy it to get
2:31
under ultrasound if necessary, so
2:34
Almost synthesis. So this is an ML. And actually
2:38
sorry, this is the mlo and this is actually an image from
2:41
an mlo tomosynthesis.
2:43
And I don't know if you've ever paid attention to this
2:46
as you scroll
2:49
through a Tomo you're going to see something that looks like this
2:52
clock and the line and so this is a
2:55
really helpful tool to help triangulate where
2:58
you are in the breast.
2:59
So in this case, where is
3:02
the abnormality located?
3:05
So I want you to tell me which quadrant this is the right
3:08
breast.
3:09
But now what quadrant is it? What are you going to tell the
3:12
tax to look for?
3:16
Okay good. So, I'm glad some people got this wrong. So.
3:20
What this is telling us is that we know it's in the upper
3:23
breath, right? So the correct answer is actually 9 to 12.
3:27
So actually I don't think I don't think anyone got that right? So it's
3:30
good that we're getting something wrong. So we're going
3:33
to learn something so we know what's in the upper breath, right? Here's her
3:36
nipple. If we go straight back then we know it's in the upper breast. So
3:39
already we either know it's in this quadrant
3:42
or this quadrant and this line is telling you that this
3:45
is where we are in the upper rest. So it's you know, it's not a straight
3:48
up and down line and oblique because the mlo is oblique. So
3:51
what this is telling us that it's in this quadrant the nine o'clock
3:54
to 12 o'clock. It's in the upper breast and we know it's in
3:57
the outer breast if it was in the lower breath.
4:00
Like let's say it was below the nipple that it would actually begin
4:03
the three to six o'clock range. So this is a really
4:06
helpful tool. If you see something on one view, you know in the
4:09
past we would get true lateral to see if it
4:12
drops or if it rises to see if it's in the medial or
4:15
lateral breath, but this is a great tool that so tomosynthesis
4:18
is really helpful for triangulation. So now
4:21
we're going to tell the tech to look in the nine o'clock to 12
4:24
o'clock.
4:25
Range, so the tech
4:28
goes in you know, really she shows me a negative picture, but I'm
4:31
worried so I go back in and I find this very
4:34
very subtle thing at 10 o'clock 10 centimeters
4:37
from the nipple. It's slightly irregular, but it's
4:40
really the right location and
4:45
We think of corresponds to the mass again.
4:48
We always look in the lymph node. That looks
4:51
fine. So that would be a buyer ads for.
4:54
And you know, it was suspicious and it ended
4:57
up being invasive ductiles.
4:59
So evolving focal or evolving a
5:02
symmetries?
5:04
Are a new or in our new
5:07
or increasing in consequute insides or
5:10
conspicuity compared to Prior mammograms? So in
5:13
this case it was developing. You
5:16
know, it got more conspicuous over time. The risk
5:19
of malignancy is high for developing asymmetry certainly over
5:23
the two percent that would warrant a biopsy. So this would certainly be
5:26
a buyer and for and if you didn't see it
5:29
on ultrasound
5:31
Then you would buy up see it under stereotactic biopsy.
5:34
I don't want you recommending an MRI really you
5:38
should be able to biopsies you don't you see it well enough
5:41
on a mammogram that you go by see under
5:44
the mammogram, but developing a symmetries have a very high risk
5:47
of malignancy certainly well over the 2% that
5:50
we would you know accept for probably benign.
5:54
So that would need to be biased.
5:56
Um a folk asymmetry
5:59
on a baseline is a different situation. So if you have a focal asymmetry
6:02
on a Baseline and you do the appropriate workup, you
6:05
get stock impression views and you do an ultrasound. There's
6:08
nothing there then you could say it's probably benign by Red 3, but if
6:11
it's a growing or new focal asymmetry or asymmetry that
6:14
needs to be addressed so that is suspicious and
6:17
should be biased one way or another.
6:20
And this is actually a great article and Radiology
6:23
the developing asymmetry. We're visiting a perceptual
6:26
and diagnostic challenge. So if you need some nighttime
6:29
reading I recommend this.
6:31
So she goes on to have breast conservation therapy,
6:34
right? It's one small little area. What
6:37
can we do in Radiology to take
6:40
out the tumor?
6:43
And I'm going to give you a minute to
6:46
answer this
6:49
so I will give you a hint. This is what it would look like if you
6:52
do this procedure.
6:56
Good.
6:58
Glad some people got this wrong. So.
7:01
And you know on the board they can certainly show you something
7:04
that looks like this alphanumeric. Grid when you
7:07
see an alphanumeric red, you know, it's a needle localization.
7:10
So need a localizations are done before surgery to
7:13
help localize something that we can't see that the
7:16
surgeon can't see or feel stereotactic biopsy
7:19
on the other hand. I wish I put a
7:22
picture of my lecture but it looks different. It's going
7:25
to have a little box. You
7:28
know what I should I'll add that for the next time but when
7:31
you see an alphanumeric grid, you know, what's a needle look and that
7:35
is what we do in mammogram and
7:38
breast Imaging to help localize it
7:41
something before surgery. You could do an or mammogram.
7:44
You can do it under ultrasound. You can do it under MRI. If you have the capability you
7:47
can put a tag in and then they take it out later. So
7:50
be familiar with those procedures because
7:53
it's something we do often.
7:57
and my question to you is
8:01
I I want people actually this is
8:04
very interactive. So I want people to jump in and if they have any questions about anything
8:07
I'm talking about. I don't know if you
8:10
guys are in practice or your residents, but certainly if
8:13
there's something I talk about you're not familiar with and you want
8:16
more information. Please let me know feel free
8:19
to ask so we want to know what size needle
8:22
are we using and what approach?
8:24
for our needle localization
8:30
good. All right, so we have things all over the
8:33
board. So I'm so happy about that and let me take a minute to explain
8:36
what is going on here. So this is the ml this
8:39
is her cliff and this is the CC view.
8:43
So what you're trying to do when you're planning for a needle Locus
8:46
you want to find the shortest skin surface.
8:49
So, you know certainly is in the upper outer breast. So
8:52
if we measure from the from the superior breast it's about seven
8:55
centimeters. If you measure from the lateral breasts, it's
8:58
4.2. So already we know we want to come from
9:01
lateral. That's just the closest skin surface. Now you
9:04
want to talk about what size Mutual you need for a needle
9:07
Loop. Typically they come in three five
9:10
seven and a half or 10, but the the real
9:13
underlying theme is that you need something that's long enough
9:16
to reach the I'm sorry. The answer
9:19
is five centimeters from lateral. It needs to be long enough that
9:22
you reach the lesion. It's okay to go past it,
9:25
but you don't want to be too short. So a three
9:28
would be too short seven and a half would be really
9:30
on you would need to pull it back because really you're
9:33
going to want the hook right kind of at the tip. So we're
9:36
going to come from Lateral with the five.
9:39
This always trips up patients residents. But
9:42
if you're coming from lateral, you're going
9:45
to be positioning the patient LM. Okay. So for
9:48
some reason it didn't show up well, but let's say that the
9:51
the clip is right here. So
9:54
you would go in at e
9:58
0.5. So that would be right here and you
10:01
basically go in straight straight with
10:05
your needle at one. Sorry. It's 0.5
10:08
in E. And then you're going to take a picture to see
10:11
that it looks like it's straight and right on top of your lesion. So
10:14
in this case it is
10:16
so all we know is is in the same plane as our
10:19
lesion, but we don't really know how deep it is
10:22
yet until we take the patient out of LM and then
10:25
put her in CC.
10:26
Okay, and so you can see that the needle goes right
10:29
to where we want it to so it's the five centimeter
10:32
is just perfect. You know, if we went
10:35
seven and a half it would be a little too deep. So once you confirm
10:38
that the needle looks good, then you're gonna put the wire through
10:41
that needle and it's going to look something like this. Okay.
10:44
So it's at our institution the
10:47
patient will go to surgery with both the needle and wire into
10:50
in their breasts. They put a little Dixie cup
10:53
and they wheel them over they usually go to same day surgery they go
10:57
to surgery and then they're going to send you a post after surgery.
11:01
They'll send you a post surgical specimen. So you're gonna you're
11:04
when you do a specimen you're making sure that you have the mass
11:07
and the clip and the whole needle and wire sometimes
11:10
make a break in the breast.
11:13
So you want to make sure that you don't leave any fragments of
11:16
that and yeah any
11:19
questions about this, this is a really important concept.
11:22
I would love you to understand so
11:26
Take a minute to look at this.
11:30
Okay, if anyone has
11:33
any questions, like I said, please feel free to ask okay?
