摘要

目的：

分析乳腺包被性乳头状癌（encapsulated papillary carcinoma，EPC）的磁共振成像（magnetic resonance imaging，MRI）特征，并探讨与良性囊实性乳腺导管内乳头状瘤（breast intraductal papillomatosis，BIDP）的鉴别。

方法：

回顾并分析广东省人民医院2014年6月2019年10月经病理学检查证实并在术前行MRI检查的10例乳腺EPC患者及10例囊实性BIDP患者的临床病理学资料。分析乳腺EPC的MRI形态学特征、时间-信号强度曲线（time-signal intensity curve，TIC）类型及表观扩散系数（apparent diffusion coefficient，ADC）的特点，并探究其与囊实性BIDP的临床及影像学表现差异。

结果：

10例EPC均为结节/肿块型，其中8例为囊实性肿块，3例出现液平，2例合并导管扩张。乳腺EPC患者的平均年龄［（65.5011.64）岁］显著大于囊实性BIDP的患者，差异有统计学意义（

=0.018）。两组患者在实性部分抑脂T2WI信号之间的差异有统计学意义（

=0.019），其余MRI特征差异无统计学意义。

结论：

乳腺EPC在MRI上常表现为囊实性结构，实性部分在T2WI抑脂相常呈高或等信号，结合患者的年龄及MRI表现有助于与囊实性BIDP鉴别。

Abstract

Objective:

To explore magnetic resonance imaging (MRI) features of encapsulated papillary carcinoma (EPC) and differential diagnosis of solid and cystic breast intraductal papillomatosis (BIDP).

Methods:

The clinical and pathological data of 10 breast EPC patients and 10 solid and cystic BIDP p

atients confirmed by pathology from Jun. 2014 to Oct. 2019 in Guangdong Provincial Peoples Hospital were retrospectively analyzed. The differences in MRI features

time-signal intensity curve (TIC) types

and apparent diffusion coefficient (ADC) between the two groups were analyzed and compared.

Results:

Average age of EPC patients was (65.5011.64) years old

which was significantly greater than that of solid and cystic BIDP patients. The difference was of statistical significance (

=0.018). All 10 EPCs presented as masses

of which 8 cases were cystic solid masses

3 showed fluid levels and breast duct dilatation was found in 2 cases. There was statistically significant difference between the two groups of cases in the signal of fat-saturated T2WI (

=0.019)

and there was no significant difference in the other MRI features.

Conclusion:

The breast EPC often presented as a solid and cystic mass and the solid part often manifested high or equal signal on fat-saturated T2WI. Combining the patients age and MRI findings could contribute to distinguish breast EPC from solid and cystic BIDP.
