Abstract
Objective To evaluated the value of a dedicated breast MRI (DBMRI) on diagnosis of breast intraductal papillomas. Methods A retrospective review of the breast MRI images of 31 cases of solitary/multiple intraductal papilloma with pathological diagnosis was performed. All the cases underwent breast DBMRI screening, as well as mammography and breast ultrasonography. The morphological analysis of papillomas included the size, shape, location, margin of the lesions, multiplicity and ductal relation, the pattern of enhancement and associated findings were evaluated. The MRI findings were categorized according to breast imaging reporting and data system (BI-RADS) lexicon. The MRI findings with mammography and breast ultrasonography was compared. Results Thirty lesions were found on MRI images in 31 cases. Among them, 23 patients had solitary intraductal papilloma and 8 patients had multiple intraductal papillomas. There were 2 cases of solitary intraductal papilloma with no positive rinding on MRI appearance, and bilateral breast multiple intraductal papilloma reviewed in 1 case. Dynamic enhanced images showed frequently multiple small nodulars or ring-like enhancement distributing along the ducts of the breast (38.7%), followed by solitary/ multiple nodular (22.6%) or ductal (12.9%) enhancement with or without ductal ectasia in the retroareolar region. Most cases had a plateau and wash-out type curve on MRI time-intensity curve. There were 4 cases (12.9%) mimicked invasive breast cancer on MRI appearance which was difficult to distinguished from malignancy. Conclusions The DBMRI shows great advantage on finding of breast papillomas compared with mammography and breast ultrosonography, which plays a valuable role in the preoperative diagnosis and localization.关键词
