What does it mean when a mammogram shows architectural distortion?

Breast architectural distortion is a descriptive term in breast imaging (mammography, ultrasound, and MRI) to indicate that the breast parenchyma is tethered or indented. The finding per se is not a mass.

What percentage of architectural distortion is cancer?

Because architectural distortion may mimic the appearance of normal breast tissue overlapped in the projected mammographic image, its detection could be difficult. Specifically, architectural distortion accounts for 12% to 45% of breast cancer cases overlooked or misinterpreted in screening mammography.

What stage of cancer is architectural distortion?

Architectural distortion is one such localized mammographic sign of possibly early stages of breast cancer that is difficult to detect 5,6. The associated patterns are vaguely described as distortion of the normal architecture of the breast with no definite mass visible.

What type of breast cancer causes architectural distortion?

The two most common types of invasive breast cancers that can produce architectur- al distortion on mammography are invasive ductal carcinoma (IDC) and invasive lobu- lar carcinoma (ILC), which represent about 70–90% and 5–10% of invasive breast ma- lignancies, respectively.

Should I worry about architectural distortion?

Architectural distortion, the non-mass but potentially ominous clinical feature observed in many breast imaging procedures, is less likely to signal malignancy when it’s detected on screening mammography rather than diagnostic mammography or when it doesn’t correlate with a subsequent targeted ultrasound exam.

What causes architectural distortion in breast?

An architectural distortion may be caused by sclerosing adenosis, or a thing called radial scar, both of which are benign and both quite rare. Breast cancer commonly causes architectural distortion. Architectural distortion uncommonly indicates cancer.

How often is architectural distortion malignant?

Conclusion: The PPV of architectural distortion for malignancy is 74.5%. Architectural distortion is less likely to represent malignancy if detected on screening mammography than on diagnostic mammography or if there is no sonographic correlate.

What causes architectural distortion in breasts?

Can fibrocystic breast cause architectural distortion?

Sclerosing adenosis is a benign form of fibrocystic change. The mammographic appearance may include a discrete mass or focal architectural distortion29 and involve calcifications that appear similar to those seen in carcinoma.

Is architectural distortion cancerous?

What does architectural distortion mean in a mammogram report?

Architectural distortion is a somewhat vague phrase used by radiologists, when the mammogram shows a region where the breasts normal appearance, looks like an abnormal arrangement of tissue strands, often a radial or perhaps a somewhat random pattern, but without any associated mass as the apparent cause of this distortion.

What is breast architectural distortion?

Breast architectural distortion is a descriptive term in breast imaging ( mammography , ultrasound, and MRI ) to indicate that the breast parenchyma is tethered or indented. The finding per se is not a mass. Article:

Does architectural distortion mean cancer?

Breast cancer commonly causes architectural distortion. Architectural distortion uncommonly indicates cancer. More common is for architectural distortion to be ‘imaginary’ in the perception of the radiologist.

What does distortion in breast mean in a mammogram?

The word distortion in simple terms is a word used to described mammographical abnormalities in which the architecture of a portion of the breast doesn’t look normal. Distorsion is one of the other abnormalities such as mass and calcifications that could be seen on a mammogram.
