Images of a 4-mm benign intraductal papilloma in a 46-year-old woman with recent onset of reproducible dark sanguinous discharge from the right nipple. The mammogram and US image (not shown) were unremarkable. (a) Craniocaudal digital galactogram obtained with the patient in a prone position shows a 4-mm rectangular filling defect (arrow) with a smaller round bubble (arrowhead) immediately inferior to it. (b) Paired craniocaudal stereotactic images show the filling defect (arrows) and bubble (arrowheads); targeting was performed by using these paired images.
