CaseA 43-year-old female with left-sided mastodynia was referred to our department for magnetic resonance imaging (MRI). Her surgical history included an excisional biopsy of a fibroadenoma in the left breast.On MRI, no explanation for the clinical complaints could be found. However, an enhancing stellate lesion (7 mm) at 9 o'clock in the contralateral right breast was noted (Figure 1B, arrowhead). The lesion had a homogeneously low signal on T1-weighted images (Figure 1A, arrow) and rapid early enhancement with plateau kinetics on dynamic contrast imaging. There was no diffusion restriction. Because of the discrepancy between the suspicious morphological findings and the rather reassuring dynamic characteristics, further mammography and breast ultrasound evaluation were recommended.On mammography of the right breast, a focal asymmetric density with spiculated margins was seen in the superolateral quadrant (Figure 2, arrow). There were no
