摘要
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.
