Mucinous Carcinoma of the Breast: MRI Features of Pure and Mixed Forms with Histopathologic Correlation Shuichi Monzawa et al AJR March 2009, VOLUME 192 NUMBER 3 乳腺粘液腺癌：纯粘液型、混合型粘液腺癌MRI特征与病理的关系 杨景震 编译 Fig. 1A —70-year-old woman with pure mucinous carcinoma. Coronal fat-saturated T2-weighted MR image shows hyperintense mass (arrow) with oval shape and smooth margin. Fig. 1B —70-year-old woman with pure mucinous carcinoma. Oblique axial early phase MR image shows mild heterogeneous enhancement predominantly at periphery of mass (arrow). Fig. 1C —70-year-old woman with pure mucinous carcinoma. Coronal delayed phase MR image shows strong heterogeneous enhancement in mass (arrow). Fig. 1D —70-year-old woman with pure mucinous carcinoma. Photomicrograph shows scattered clusters of tumor cells (grade 1 cellularity) in mucous lakes. (H and E, ×1) 纯粘液腺癌 A B C D Fig. 2 —58 year-old woman with pure mucinous carcinoma. Coronal fat-saturated T2-weighted MR image shows hyperintense mass (arrow) with irregular shape and irregular margin. 纯粘液腺癌 Fig. 3A —48-year-old woman with large pure mucinous carcinoma. Coronal fat-saturated T2-weighted MR image shows hyperintense mass (arrow) with lobulated shape and irregular margin. Dark internal septations appear as isointense lines in mass. Fig. 3B —48-year-old woman with large pure mucinous carcinoma. Oblique axial early phase MR image shows mass (arrow) with strong heterogeneous enhancement and dark internal septations. Fig. 3C —48-year-old woman with large pure mucinous carcinoma. Sagittal delayed phase MR image shows mass (arrow) with strong heterogeneous enhancement. Dark internal septations are less evident than in A and B. 巨大纯粘液腺癌MRI Fig. 3D —48-year-old woman with large pure mucinous carcinoma. Photomicrograph shows marked proliferation of tumor cells with mucin collection (grade 3 cellularity). Thick fibrous septa (arrows) are evident between tumor cell clusters. (H and E, ×1) 巨大纯粘液腺癌病理图 Fig. 4A —45-year-old woman with pure mucinous carcinoma. Coronal early phase MR image shows irregularly shaped mass (arrow) with strong rim enhancement. Fig. 4B —45-year-old woman with pure mucinous carcinoma. Photomicrograph shows marked proliferation of tumor cells at periphery and mucous lake (asterisk) interspersed with small clusters of tumor cells in center of mass (grade 2 cellularity).
