摘要

目的：

探讨乳腺包裹性乳头状癌(encapsulated papillary carcinoma，EPC)的影像学表现特点。

方法：

回顾性分析13例乳腺EPC的影像学资料。11例行乳腺X线摄影、超声检查及MRI检查，2例行乳腺X线及超声检查。

结果：

13例EPC均为Luminal A型乳腺癌，无淋巴结转移。9例EPC位于乳晕后方，4例位于外周。11例EPC最大径2 cm，2例＜2 cm。X线显示12例EPC为单发肿块，1例阴性。13例EPC均测得彩色多普勒血流信号，10例测得动脉频谱。MRI图像中，时间-强度曲线(time-intensity curve，TIC) Ⅱ型4例，Ⅲ型7例。扩散加权成像(diffusion weighted imaging，DWI)呈高信号3例，稍高信号8例；9例表观扩散系数(apparent diffusion coefficient，ADC)＜1.3110

结论：

乳腺X线难以发现EPC的特异性征象，超声检查测得动脉频谱时提示恶性，MRI表现强化方式、ADC值1.1310

Abstract

Objective:

To observe the imaging features of encapsulated papillary carcinoma (EPC).

Methods:

Imaging results of 13 women with EPC were retrospectively analyzed. Eleven patients underwent mammography

ultrasound and MRI examinations

and 2 young cases were examined by mammography and ultrasound.

Results:

Nine lesions were located behind the areola

and 4 in peripheral. Eleven lesions diameter 2 cm

and 2 2 cm. X-ray showed 12 cases with single lesion

and 1 negative. Color Doppler flo

w imaging (CDFI) showed blood flow signals in 13 lesions

and arterial spectrum appeared in 10 lesions. The timeintensity curve (TIC) appeared as type III in 7 cases and type II in 4 cases. Diffusion weighted imaging (DWI) showed high signal in 3 cases

slightly high signal in 8 cases. Apparent diffusion coefficient (ADC) value in 9 case was 1.3110

-3

and in 2 cases 1.3110

-3

/s. All EPC lesions belonged to Luminal A.

Conclusion:

It is difficult for mammography to find the specific signs of EPC. The appearance of arterial Doppler spectrum indicates the possibility of malignancy. Breast MRI shows great advantages in finding of EPC

especially the TIC pattern and ADC value 1.3110

-3

which are correlated with the pathological findings.
