2015年12月17日 · 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 does not correlate with a subsequent targeted ultrasound exam.

2023年3月23日 · 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.

2024年8月30日 · Architectural distortion. Architectural distortion is a term most often seen with inflammatory breast cancer (IBC) and lobular carcinoma. As the name suggests, it indicates a change in the actual structure of the breast. On imaging, it looks like someone is pinching a napkin or pulling down a curtain.

2022年11月30日 · Architectural distortion describes a distorted shape or pattern of breast tissue on a mammogram. However, no mass is seen. Although the breast tissue may be normal, this finding usually needs follow-up testing because it may be a sign of a benign (not cancer) breast condition or breast cancer.

Figure 1 shows a classic mammogram appearance of architectural distortion. As denoted by the red circle, abnormal, fine tissue lines can be seen emanating in a radial pattern and appear to originate from a central focal region.

2019年5月5日 · An architectural distortion on a mammogram is basically a disruption of the normal ‘random‘ pattern of curvilinear and fine linear radiopaque structures normally seen on a breast X-ray. There is no visible mass, but the distortion often appears as a ‘ stellate ‘ shape or with radiating speculations.

2013年10月22日 · Architectural distortion is present on up to 80% of mammograms at 6 months after excisional biopsy, decreasing to 35% at 2 years. Ultrasound rarely shows frank distortion after benign breast biopsy but can reveal an irregular hypoechoic mass with posterior shadowing.

2015年11月20日 · Architectural distortion on mammography, defined as distortion of the breast parenchymal architecture without a definable mass, can be due to malignant lesions, such as invasive cancer or ductal carcinoma in situ (DCIS), or to benign lesions, such as a radial scar or complex sclerosing lesion [1–6].

A post-biopsy mammogram confirmed accurate positioning of the biopsy microclip at the site of architectural distortion. Pathology revealed invasive ductal carcinoma, grade 1 estrogen receptor negative, progesterone receptor negative, and HER2 positive.

2023年5月12日 · Architectural distortion (AD) on mammography (MG) is defined as an altered appearance of normal breast parenchyma in the absence of a visible mass. The appearance can manifest as focal parenchymal distortion or retraction, radiating straight lines or spiculations, straightening of parenchymal edges, or blurring of normal tissue planes ( 1 ).
