A case of contralateral recurrent breast cancer which was not apparent on AB-MRI. A 53-year-old female, who had left total mastectomy with flap reconstruction for IDC 1.5 years ago, underwent post-operative screening MRI. Dynamic contrast-enhanced images (a) consisted of pre-, and two post-contrast sequences showed no abnormal enhancement in right breast. Screening mammography 6 months after the AB-MRI (b) showed grouped coarse heterogeneous microcalcifications (arrow) in right upper outer breast. Stereotactic vacuum-assisted biopsy was performed and the lesion was confirmed as ductal carcinoma in situ. Following surgery revealed intermediate grade invasive ductal carcinoma. AB-MRI, abbreviated protocol of breast MRI; IDC, invasive ductal carcinoma.
