Pseudoangiomatous stromal hyperplasia. A 41-year-old woman presented with a palpable breast mass. Mediolateral oblique mammogram (a) shows a high-density well-circumscribed mass (arrow). Longitudinal grayscale ultrasound (b) shows a large, oval circumscribed mass. Core needle biopsy showed pseudoangiomatous stromal hyperplasia (PASH). A different patient, a 40-year-old woman, was found to have a new breast mass (arrow) on mammography, craniocaudal spot view (c). Transverse grayscale (d) ultrasound reveals a corresponding oval isoechoic circumscribed mass. Core needle biopsy showed PASH
