乳腺导管内乳头状瘤的乳腺专用磁共振成像表现及其诊断价值

Intraductal papilloma:features on dedicated breast magnetic resonance imaging

目的:探讨乳腺导管内乳头状瘤在乳腺专用磁共振成像(DB-MRI)上的表现及其诊断价值。方法:回顾性分析行乳腺专用磁共振成像并经病理证实的40例导管内乳头状瘤患者的病例资料,探讨其MRI特征及诊断价值。结果:40例中39例显示强化(占97.5%),其中36例表现为结节样强化,3例为条状强化;1例仅见导管扩张(占2.5%),未见明显强化病灶。主要MRI表现可归纳为5种:边缘光滑结节型(55%,22/40)、边缘不光滑结节型(25%,10/40)、囊内结节型(10%,4/40)、条状强化型(7.5%,3/40)和无强化型(2.5%,1/40)。结论:乳腺专用磁共振成像可以很好地显示及诊断乳腺导管内乳头状瘤。

Objective：To investigate the appearances of intraductal papilloma of breast on DBMRI. Methods：A retrospective review of MR images of 40 pathologically proven papillomas of the breast was performed. Results： Thirty-nine cases showed enhancement （97.5%）,including thirty-six cases showed nodular enhancement and three cases showed linear enhancement. The imaging features of the intraductal papillomas in these patients could be divided into five patterns：well-circumscribed nodular （55 %, 22/40）, ill-defined nodular （25 %, 10/40）, intraeystic nodular （10 %, 4/40）, linear enhancement type （7.5% ,3/40） and no enhancement type （2.5%, 1/40）. Conclusion： Intraductal papillomas can be detected and diagnosed accurately by using DBMRI.
