So I want to talk about some associated
0:03
features that we can see on MRI, and these
0:06
include things like nipple retraction, nipple
0:09
inversion, skin retraction, and skin thickening.
0:12
We may see skin invasion, where the breast
0:17
tumor directly invades the skin, or there's
0:20
inflammatory breast cancer where there's
0:23
actually metastatic disease within the skin.
0:26
We can see axillary adenopathy, pectoralis
0:29
muscle invasion, chest wall invasion,
0:32
and associated architectural distortion.
0:35
I wanted to show you a few of these features
0:38
and then we'll go over a case that has a
0:40
lot of these features associated with it.
0:43
So this is a patient
0:44
who has inflammatory breast cancer and
0:47
her breast skin is diffusely thick, and
0:52
her nipple is actually retracted here.
0:54
So the nipple, the shape of the
0:56
front of the breast is a little bit
0:57
deformed and her nipple is pulled in.
1:00
This is a patient who has a breast cancer
1:03
that's involving her pectoralis directly, almost
1:08
extending to the back of the pectoralis muscle.
1:11
So pectoralis involvement.
1:14
And here's a patient who
1:16
has a large breast cancer.
1:19
It actually extends from the skin to the
1:23
pectoralis muscle, but it doesn't stop there.
1:25
It goes to the chest wall.
1:29
So that yellow arrow is
1:30
indicating chest wall enhancement.
1:34
You can see that that's pretty diffuse.
1:37
So sometimes we'll have a request to look at
1:40
breast MRI when we have kind of a larger mass
1:43
or a fixed mass, it's already been biopsied,
1:46
we know it's a breast cancer, but we're trying
1:48
to figure out what structures are involved
1:52
and how can we help the surgery team and
1:55
treatment team better plan for treatment.
