摘要
目的:探讨乳腺小叶原位癌的X线摄影(MG)、超声(US)及MRI表现。方法:运用美国放射学会提出的乳腺影像报告和数据系统(BI-RADS)分析手术病理证实为小叶原位癌14例患者的MG、US及MRI表现。结果:乳腺小叶原位癌最常见的X线表现为成簇多形性微钙化(7例)。最常见的超声表现为肿块(11例)、不规则形(8例)、低回声(9例)、水平位生长(10例)。最常见的MRI表现为非肿块样强化(9例)、流出型曲线(8例)。结论:乳腺小叶原位癌的影像学表现具有一定的特征,但与导管原位癌存在一定重叠,确诊需依靠病理、免疫组织化学检查。
Objective：To investigate the mammographic,ultrasonographic,and MRI features of lobular carcinoma in situ （LCIS）.Methods：We analyzed 14 cases of LCIS proved by pathology in our hospital.Mammographic,ultrasonographic and MRI features were retrospectively reviewed according to the American College of Radiology （ACR）Breast Imaging Re-porting and Data System （BI-RADS）.Results：The most common mammographic finding was clustered pleomorphic micro-calcifications.The most common ultrasonographic findings were irregular mass,circumscribed margin,hypoecho,and parallel orientation.At MRI,the most common findings were non-mass enhancement,and the time-signal intensity curve appeared as type Ⅲ.Conclusion：LCIS of the breast has certain MRI features;however,there＇s an overlap between LCIS and DCIS.The pathological and immunohistochemical results are required to establish the final diagnosis.
