Abstract

Abstract

Architectural distortion on digital breast tomosynthesis (DBT) can occur due to benign and malignant causes. DBT is a mammographic technique that incorporates multiple angular projections of the breast to enable three-dimensional reconstruction while only compressing the breast once. DBT creates a better detection of distortion compared to a 2D mammography. Architectural distortion is found when the two breasts are compared and one breast has an abnormal tissue pattern. When examining the two breast with each other they should mirror one another, so when there is architectural distortion there could be contour abnormalities, trabecular thickening, and trabecular disorganization. When architectural distortion becomes questionable on diagnostic imaging, MRI may be performed. Along with MRI, ultrasound is another tool used to help in the final diagnosis of benign or malignant. Malignant cases are more noted in 6.8%-50.7% of the cases due to ductal carcinoma. Architectural distortion on DBT is less likely to represent malignancy if there is no sonographic correlate. Few studies have focused on tomosynthesis detected architectural distortions to date, and optimal management of these distortions have yet to be distinct.
