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
