Imaging of benign papillary neoplasm of the breast: mammographic, galactographic and sonographic findings.

We have retrospectively reviewed the mammographic, galactographic and sonographic findings of our 15 patients with histologically proved benign papillary neoplasm of the breast. Ten (67%) of 15 patients had breast masses and central location in 8 cases. We analyzed the mammographic findings in aspect of number, contour, outline, location, density, calcification and associated disease. Mammographic findings showed a mass in 10 cases (67%) and dense breasts in 5 cases (33%). The almost masses were round (6 in 10 cases) and solitary (9 in 10 cases). None of them had calcification. Ten of 15 cases who had nipple discharge had galactogram performed. The galactographic findings showed abnormal intraductal filling defect (s) in all 10 cases, and duct dilatation in 3 cases (30%). Sonography was performed in all cases. Sonographic findings were cystic mass with intramural nodule in 6 cases (40%), solid mass in 4 cases (27%), single duct dilatation at subareolar area with intraechoic nodule in 2 cases (13%) and was negative in 3 cases (20%).
