The history here is 80-year-old woman
0:02
status post bilateral mastectomy
0:04
presented for implant assessment.
0:06
So this is one case, uh,
0:08
covers, uh, many illustrations.
0:10
So this, we're starting at the top.
0:12
These are the, of course, non-fat sat.
0:14
You see all of her fat.
0:15
And as we're coming down, all of a
0:17
sudden we realize, wait a minute, not
0:18
only do I not see one normal breast,
0:20
uh, I don't even see two normal breasts
0:22
because it is obvious that the right
0:25
breast doesn't have the usual parenchyma.
0:27
There's an odd, um, there's skin thickening,
0:31
and then there's an odd band of hypointensity.
0:35
And then the pack is more pointed than usual.
0:38
There's also this oddity
0:40
of these swirls of vessels.
0:43
And, of course, here's some
0:45
overt post-surgical change.
0:47
And so, of course, by now, and
0:50
then, as we scroll down, you can
0:51
see by now, you're reconciling the
0:55
status post bilateral mastectomies.
0:57
Quote implant, um, uh, integrity indications
1:01
of this MR with the fact that, hey, wait a
1:04
minute, one breast doesn't have an implant.
1:06
That is an autologous, um, reconstruction.
1:10
So that's a, that's a flap and
1:12
the other and the left breast does
1:14
in fact have a silicone implant.
1:16
So, um, anyway, so these are the
1:18
hallmarks actually of a TRAM.
1:20
Um, and, um, just wanted to go through
1:23
that very quickly, and then we'll, we'll
1:26
do a bit more on the silicone as well.
1:28
But this is the, so what happens is the normal
1:30
breast has been removed with the exception.
1:33
And this is important to know, in terms
1:35
of where you might look for recurrence.
1:37
This is actually endogenous
1:40
um, tissue that remains,
1:43
uh, underneath the skin.
1:45
Um, this line is the pulled-through flap, in
1:50
this case, a TRAM flap coming from the abdomen.
1:53
So all of this fat is abdominal fat, whereas
1:56
this fat is the, is the, um, just barely
2:00
beneath the skin, but could theoretically
2:03
still contain some, um, some breast,
2:06
um, breast, breast, epithelial rest.
2:08
So just a little hint there, um, and,
2:12
um, and then this, these structures
2:15
here reflect the actual vascular
2:17
pedicle of the pulled-through flap.
2:20
And then this is, um, this is, um, the,
2:24
atrophied rectus abdominal muscle that.
2:28
That's come to come up with a
2:29
pull through and all of that.
2:31
So that's just a very, very typical anatomy.
2:34
I'm not going to belabor that
2:36
on this one because actually
2:37
the next case is a TRAM as well.
2:38
Just FYI.
2:39
Okay, so we have that information and
2:41
so again, the value, the value, at least
2:44
to me of anatomic assessment, we already
2:47
know that there is no intrinsic amount of.
2:53
Fibroglandular tissue, so
2:54
you get to say not applicable.
2:55
You also know that there's not going
2:56
to be a background enhancement.
2:58
So you get to say not applicable.
3:00
And so also that sequence kind of helps
3:03
you with kinds of kind of helps you with
3:05
that determination and then we're going
3:07
to move on from here to, um, one of the
3:11
things that can be the silicone implant.
3:14
Admittedly, this is a T2, but you can use a
3:16
T2 sequence to at least look at the overall
3:20
anatomy and appearance of the implant.
3:23
So here's that we're starting up
3:24
high coming down low the left.
3:26
breast has been, um, uh, removed as
3:29
well, but it has been reconstructed.
3:31
They were not done at the same time, obviously
3:33
they were done in tandem and the left breast
3:35
was reconstructed with a silicone implant.
3:37
We know it's a silicone implant.
3:39
We wouldn't know so much from this T2 because
3:41
of course T2, uh, salines are bright, but there
3:44
is no valve as you scroll through all of it.
3:46
There's no valve.
3:47
And, um, you can.
3:48
Absolutely.
3:49
Thereby exclude from being a silicone
3:52
saline implant, because there's no,
3:53
there's no apparatus to reinflate it.
3:56
And then remember on the silicone
3:58
implants, we want to always do something.
4:00
That is a silicone only sequence.
4:03
That is silicone hyperintense
4:05
and water hypointense.
4:07
So that, like, teach regular to is not
4:10
going to be that because a regular to is.
4:12
Of course, water bright, it doesn't
4:14
help so much silicone versus saline or
4:17
silicone versus any fluid structure.
4:20
But this is a very nice example of a completely
4:23
intact, smoothly contoured silicone implant.
4:27
And these are the radial
4:29
folds that occur at the perimeter.
4:31
Uh, there's no silicone in the middle of them.
4:34
These are not anything with the keyhole or the
4:38
or the teardrop or the new
4:40
signs and so that's it.
4:43
So the only 2 points that I was going
4:45
to make with this case to reiterate them
4:47
again is what a silicone implant looks
4:50
like when it has not failed and what the
4:53
autologous flaps, notably a TRAM flap, which
4:56
at least in the States is far more common.
