We report magnetic resonance (MR) imaging findings of ductal carcinoma in situ (DCIS) within a fibroadenoma in a 42-year-old woman. Dynamic MR imaging revealed the mass to have 2 components with different kinetics. A nodular area within the mass showed faster initial enhancement followed by earlier washout and was histologically proven to be DCIS. Dynamic MR imaging reflected differences in vascularity between the fibroadenoma and DCIS, and parameter color maps generated from the dynamic data clearly demonstrated the extent of the DCIS.
我们报告了一例 42 岁女性纤维腺瘤内导管原位癌（DCIS）的磁共振（MR）成像表现。动态 MR 成像显示肿块有 2 个部分，具有不同的动力学特征。肿块内的一个结节区域表现出更快的初始增强，随后更早的廓清，组织学证实为 DCIS。动态 MR 成像反映了纤维腺瘤和 DCIS 之间的血管差异，并且来自动态数据的参数彩色地图清楚地显示了 DCIS 的范围。
