2 m.0:01
This is a companion case, but this
0:03
is sort of the ultrasound companion.
0:05
This is a patient who had had bilateral
0:07
breast reduction and came in with a palpable
0:10
area of concern in the right breast.
0:13
And the image to the left is what we saw initially.
0:16
This was an echogenic oval mass
0:18
with circumscribed margins.
0:21
And it measured just over 2 centimeters, 2.1 centimeters
0:28
by, let's see, it's 2.1 by 0.8 by 2.4 centimeters.
0:34
This was right in the area
0:35
where she had had her reduction.
0:37
It has this echogenic appearance that looks like...
0:41
it's probably fat necrosis, but it was palpable.
0:45
We recommended to do a short-term follow-up,
0:48
a three-month follow-up, to see how this finding
0:51
evolved over time rather than doing a biopsy.
0:54
On the right is her three-month follow-up
0:56
exam, and you can see that this finding
0:58
has decreased in size pretty significantly.
1:00
Now it measures 1.4 by 0.8 by 2.1 centimeters.
1:10
This is quite a bit smaller in size.
1:12
And we know cancer doesn't decrease in size,
1:14
but necrosis will decrease in size over time.
1:17
So given this change over time where it's decreasing
1:21
in size, I feel confident that this is a benign
1:24
finding, and we're able to change it at that follow
1:27
up appointment from the BI-RADS 3 to a BI-RADS 2.
