MR Imaging of Mucinous Carcinoma of the Breast Associated with Ductal Carcinoma In Situ: Case Report

ABSTRACT

A mucinous carcinoma of the breast is an uncommon carcinoma containing mucin that is associated with a mucocele-like tumor or other malignant tumors. We report the MR imagingfindings of two cases, a mucinous carcinoma and ductal carcinoma in situ (DCIS), associated with mucocele-like tumor. The mucinous carcinoma showed a gradually enhancing kinetic pattern on the dynamic MR and high signal intensity on the T2-weighted images. The MR findings were indistinguishable from a common benign mass of the breast.
