摘要
背景与目的:乳腺导管原位癌(ductal carcinoma in situ,DCIS)属于乳腺浸润性癌的前驱病变,是一类非全身性的导管内局部病变,与其他导管内病变在影像上存在相似之处。本研究旨在探讨乳腺MRI鉴别诊断DCIS与其他乳腺导管内病变的价值。方法:回顾性分析2011年7月—2012年2月于复旦大学附属肿瘤医院行乳腺MRI检查并经手术病理证实的DCIS患者24例、DCIS伴微浸润(breast ductal carcinoma in situ with microinvasion,DCIS-MI)9例、乳腺导管内乳头状瘤(breast intraductal papilloma,BIDP)20例临床资料。以DCIS为研究主体,分析3种病变MRI及动态增强表现。结果:DCIS与DCIS-MI的病灶强化形态、强化方式、时间-信号强度曲线(TIC)、病灶伪彩图像间差异均无统计学意义(P>0.05),而DCIS与BIDP的病灶强化形态、强化方式、TIC、病灶伪彩图像间差异均有统计学意义(P<0.05)。DCIS以导管样(8/24)及段样强化(6/24)为主、病灶伪彩图像为红色(22/24)、TIC以Ⅲ型(12/24)为主要特征性表现;BIDP以乳头后局灶性强化为主(13/20)、病灶伪彩图像为非红色(14/20)、TIC以Ⅱ型(11/20)为主要特征性表现。结论:MRI较难鉴别DCIS与DCIS-MI,但具有鉴别诊断DCIS与BIDP的价值。
Background and purpose： Ductal carcinoma in situ （DCIS）, is precursor lesions of invasive breast cancer, belongs to non-systemic ductal lesions, which is similar to other ductal lesions on imaging. This study aimed to investigate the differential diagnostic value of MRI in DCIS between DCIS with microinvasion （DCIS-MI） and breast intraductal papilloma （BIDP）. Methods：All the cases were surgico-pathologically conifrmed. Twenty-four patients were DCIS, 9 patients were DCIS-MI, and 20 patients were BIDP. The MRI charateristics of DCIS, DCIS-MI and BIDP were analyzed and compared. Results：DCIS and DCIS-MI’s performance in the form of MRI is dififcult to differentiate （P〈0.05）. Compared with BIDP, the ductal and segmental enhancement, typeⅢtime-signal intensity curve （TIC）, and the red pseudo-color image were associated with the DCIS. The local area enhancement, typeⅡTIC, and no-red pseudo-color image were associated with BIDP. Conclusion：MRI is a useful for differentiate between DCIS and BIDP, but is dififcult for DCIS and DCIS-MI.
