Stromal fibrosis. A 55-year-old woman presented for a focal asymmetry detected on screening mammography. Craniocaudal (a) and lateral (b) spot compression mammographic views show an oval non-calcified mass with angular margins (arrows). Grayscale transverse (c) and longitudinal (d) ultrasound show a mixed-echogenicity oval mass correlating with the mammographic finding (arrows). Ultrasound-guided biopsy yielded stromal fibrosis. Six-month follow-up mammography and ultrasound were recommended and demonstrated stability
