As tomosynthesis use becomes more widespread, appropriate management of tomosynthesis-detected architectural distortion will be needed. Workup should be directed towards sampling the lesion, and usually involves the use of another modality such as US or MRI. The pathology of lesions that present as tomosynthesis-detected architectural distortion is variable and includes benign etiologies such as radial scars and proliferative fibrocystic changes, as well as malignant invasive ductal and invasive lobular cancers.

I Architectural Distortions Detected by Tomosynthesis   a. Appearance of architectural distortions   b. Optimizing visualization of architectural distortions II Management of Tomosynthesis-detected Architectural Distortion   a. Ultrasound Correlation and Biopsy     - Imaging and pathology correlation of benign and malignant cases     - Morphologic features and histologic diagnoses of distortions that more consistently have an ultrasound correlate.   b. MRI Correlation and Biopsy     - Imaging and pathology correlation of benign and malignant cases     - Morphologic features and histologic diagnoses of distortions that more consistently have an MRI correlate c. Architectural distortions with no US or MRI correlate     - Stereotactic Biopsy     - Needle Localization III Summary of Management Algorithm
