Background
Stromal fibrosis is a benign histopathologic entity characterized by proliferation of stromal fibrous tissue with obliteration of mammary acini and ducts. It may present as a palpable mass or as a clinically occult imaging-detected abnormality. Collectively, it has been reported to represent as high as 9% of the breast lesions biopsied. The purpose of this exhibit is to present various imaging appearances of stromal fibrosis on mammography, ultrasound, and MRI.

Educational Goals / Teaching Points
On imaging, stromal fibrosis may present with either benign or suspicious for malignancy features. Our goal is to review these imaging features and management of these lesions.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The key points of this exhibit include – histopathology and imaging features on mammograms, ultrasound, and MRI with illustrative cases and short discussion with practical points (i.e., benign, probably benign, suspicious, and management).

Conclusion
Stromal fibrosis may present with either benign or malignancy features on imaging. In case of accurate targeted biopsy, when stromal fibrosis is diagnosed, the result can be considered possible concordant. Such lesions can be followed up by imaging to document stability and confirm benignity.
