Architectural Distortion Overview

HIDE
PrevNext

0:00

Our next potential recalled finding is

0:03

architectural distortion, and our protocol for

0:09

looking at these is to do a spot compression

0:12

views in both the CC and MLO projection

0:14

and a full lateral view, and then possible

0:17

ultrasound depending on whether we think

0:19

that there may be an ultrasound correlate.

0:21

And if the screening mammogram was done in

0:23

2D, then we would begin with full CC and MLO.

0:27

Tomosynthesis images with

0:29

additional evaluation as needed.

0:32

And there are some studies that have

0:33

shown that architectural distortion

0:36

is much more commonly identified on

0:38

tomosynthesis compared to 2D and also more

0:41

likely to be malignant if detected on 2D.

0:44

A recent study by Ambinder et al

0:47

showed a 19 percent malignancy rate

0:50

on tomosynthesis-guided biopsy.

0:52

So if you have a distortion on tomosynthesis, uh,

0:56

no ultrasound correlate, you know, just biopsying

1:00

the distortion, the malignancy rate is 19%.

1:03

So really, I think that what that shows

1:06

is that if there's really no explanation

1:08

for the distortion, it requires a biopsy.

1:11

So these are some of the reasons that we can

1:13

see architectural distortion in the breast:

1:16

prior surgery, prior trauma,

1:19

stromal fibrosis, sclerosing adenosis,

1:22

radial scar, complex sclerosing lesion,

1:26

and invasive ductal and invasive lobular carcinomas.
