ABSTRACT
<p><b>OBJECTIVE</b>To investigate the features of intraductal papilloma of the breast in mammography and magnetic resonance imaging (MRI) and assess the diagnostic values of the two imaging modalities.</p><p><b>METHODS</b>Fifteen patients with intraductal papilloma of the breast confirmed surgically and pathologically underwent X-ray examination of the breast, and 11 of them also received enhanced MRI. The imaging findings by mammography and MRI were compared.</p><p><b>RESULTS</b>Enhanced MRI clearly displayed the location and morphology of the intraductal papilloma, and 7 patients showed smooth tumor margins and 2 showed irregular margins. On T(1)WI, the lesions were isointense or slightly hypointense, and appeared isointense or slightly hyperintense on T(2)WI. Some of the intraductal papillomas were seen encapsulated in the dilated ductal. The varying enhancement features of the lesions increased the difficulty in distinguishing from carcinoma. Mammography identified intraductal papillomas only in 2 of the 15 cases (13%) with lesion feature similar to that found by MRI. Fine cluster calcification was found in 1 case.</p><p><b>CONCLUSION</b>MRI can more accurately define the location of the lesion than X-ray. In spite of some resemblance in the MRI findings between intraductal papillomas and breast carcinoma, MRI still serves as a useful diagnostic modality for intraductal papilloma that shows some characteristic findings.</p>
