摘　　要：目的探讨乳腺包裹性乳头状癌的超声及MRI影像特点。方法回顾性分析我院经病理证实的4例IMPC患者的临床病理结果及US、MRI影像表现。结果乳腺包裹性乳头状癌最常见的US表现为分叶状3例,卵圆形1例,边界清晰3例,不清1例,内部回声均不均匀,后方回声增强3例,后方回声无改变1例,病灶实性可见到至少1条血管,实性成分边缘不规则。MRI表现为3例均为分叶状,边界清晰(2例),不清(1例),实性成分T1WI呈等高信号,T2WI呈稍高信号,囊性成分T1WI呈高信号,T2WI呈高信号;增强后病灶实性成分明显强化,TIC为平台型(2)和流出型(1),实性成分边缘不规则。结论在超声及MRI影像特点中,征象对诊断乳腺包裹性乳头状癌的诊断更有价值,综合分析2种影像检查方法,有利于提高其诊断准确率。Objective To discuss the imaging features of ultrasonography（US） and MRI（magnetic resonance imaging） for breast encapsulated papillary carcinoma. Methods Retrospective analysis was conducted on the clinicopathologic results and US/MRI imaging findings of 4 IMPC patients pathologically confirmed by our hospital. Results The most common US findings of breast encapsulated papillary carcinoma were lobulation in 3 cases, oval in 1 case, clear border in 3 cases, unclear border in 1 case, uneven internal echoes in all cases, enhanced posterior echoes in 3 cases, unchanged posterior echoes in 1 case, at least 1 blood vessel seen in solid lesions with irregular edge of the solid component. MRI showed lobulation in 3 cases, with clear border in 2 cases and unclear border in 1 case, equal or high signal presented in the solid component by T1 WI, slightly high signal presented by T2 WI, high signal presented in the encapsulated component by T1 WI, high signal presented by T2 WI, after enhancement, solid components of the lesions were significantly intensified, TIC presented platform type（2） and outflow type（1）, and the edge of solid components was irregular. Conclusion In terms of imaging features of ultrasonography and MRI, the signs are more valuable to the diagnosis of breast encapsulated papillary carcinoma. A comprehensive analysis on the two kinds of imaging examination methods will help to improve its diagnostic accuracy.
