| 摘 要： | 目的探讨乳腺实性原位乳头状癌(SPC)的MR影像表现。方法回顾性分析5例经手术病理证实的乳腺原位SPC患者的资料,观察其术前常规MR平扫、动态增强扫描及DWI表现。结果原位SPC病灶T1WI脂肪抑制梯度回波(FSPGR)序列平扫表现为等和/或稍低信号,FSE T2WI、短时反转恢复(STIR)序列平扫表现为等和/或稍高信号;动态增强MRI表现为边界清楚的椭圆形或不规则形强化,病灶内部强化均匀或不均匀。时间信号强度曲线早期快速上升,晚期呈平台型或流出型。DWI病灶均表现为高信号,ADC值1.34×10~(-3)~1.96×10~(-3) mm~2/s。结论原位SPC的MRI表现具有一定特征,可为其诊断及与其他浸润性乳腺癌的鉴别提供参考信息。

| Abstract: | Objective To evaluate MRI characteristics of solid papillary carcinomas (SPCs) in situ of the breast.Methods A retrospective study included 5 patients with pathologically confirmed SPC in situ was performed. MRI data before operation including conventional MRI, dynamic contrast enhanced MRI (DCE-MRI) and DWI were analyzed.Results All the lesions showed iso/hypointensity on T1 FSPGR sequence, iso/hyperintensity on FSE T2WI sequence and STIR sequence. Mass enhancements were observed for all lesions with oval or irregular shapes on DCE-MRI. The margin of lesions were circumscribed, and internal enhancements were homogeneous or heterogeneous. Time intensity curve appeared a rapid increase in initial contrast phases and platform or outflow types in delayed phases. All the lesions on DWI showed slightly hyperintensity with the ADC value range from 1.34×10-3 mm2/s to 1.96×10-3 mm2/s.Conclusion MRI manifestations of SPC are characteristics, which may provide valuable information to distinguish SPC in situ from other invasive breast carcinomas. |
