Objective To investigate the imaging features of breast intraductal papilloma without nipple discharge on high-frequency and color doppler ultrasound. Methods This retrospective study evaluated 62 patients (73 lesions) without nipple discharge with pathologically-confirmed intraductal papilloma. According to the characteristics of the ultrasound images, 73 lesions were divided into 5 types. Type I:nodules accompanied with dilated ducts, Type II:cystosolid nodules, Type III:solid nodules, Type IV:cystic nodules, and TypeV:duct dilatation. Results Among the 73 lesions, 27 of them were classified into type I. And 11 lesions showed as cystosolid nodules were classified into type II.30lesionsconsisted of nodules without dilated ducts were classified into type III. 3 lesions showed as cystic nodules alone were classified into type IV. The other 2 lesions presented as dilated ducts only were classified into type V. The correct rates of ultrasound diagnosis of each type were: 88.9%, 90.9%, 40.0%, 0, 0, respectively. Conclusion The imaging features of intraductal papilloma without nipple discharge on ultrasound are diversity, and their typical features on ultrasound images are presented as nodules accompanied with dilated ducts and cystosolid nodules. Analysis of the imaging features on ultrasound may be beneficial to improve the accuracy of diagnosis of intraductal papilloma without nipple discharge.
