OBJECTIVE: The purpose of our study was to describe the MRI findings of metaplastic carcinoma of the breast and to compare those findings with underlying histopathologic features. CONCLUSION: Metaplastic carcinoma of the breast shows high signal intensity on T2-weighted MRI. This finding is related to the necrotic component of the tumor and may be useful for preoperative diagnosis of metaplastic carcinoma of the breast, although it must be differentiated from mucinous carcinoma and, less frequently, necrotic infiltrating ductal carcinoma.
