stromal fibrosis of the breast

Mimickers of

breast malignancy: imaging findings, pathologic concordance and clinical management. 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

Mimickers of

breast malignancy: imaging findings, pathologic concordance and clinical management. Stromal fibrosis. A 48-year-old female presented with a palpable breast mass. Spot compression tangential (a), mediolateral (b), and craniocaudal (c) mammographic views did not show a corresponding abnormality. Grayscale (d) and power Doppler (f) ultrasound images reveal an irregular mass with posterior acoustic shadowing corresponding to the palpable area. Core needle biopsy of the mass showed stromal fibrosis without evidence of malignancy
