Secretory carcinoma of the breast is an extremely rare, clinically and histologically distinct variant of invasive ductal carcinoma, with an indolent growth pattern and a more favorable prognosis than that of typical ductal carcinoma. Few studies have described its imaging features. Herein, we report on a secretory breast carcinoma with findings from various imaging modalities, especially including the MRI findings, which appears a well-defined complex cystic mass. Awareness of its imaging features using various modalities will be helpful for the differential diagnosis.
