Metaplastic carcinoma (MPC), an uncommon but often aggressive breast cancer, can be challenging to differentiate from other types of breast cancer and even benign lesions based on the imaging appearance. These types of tumors are generally rapidly growing palpable masses. MPCs on imaging can present with imaging features similar to invasive ductal carcinoma and probably even benign lesion. Although many clinical and pathological finding have been reported, to the best of our knowledge, few imaging features have described changes in mammography over 4 months, as detailed in this report.
