a Mammography. b Ultrasound. cf MRI images. c Subtraction. d Post-contrast. e T2 WI. f STIR WI. g Time/signal intensity curve. Mammography showing heterogeneous dense breast (ACR C). Right axillary tail pleomorphic clustered microcalcifications are seen (circle) with parenchymal distortion. Ultrasound showing ill-defined hypoehoic soft tissue lesion at the axillary tail of the right breast, with surrounding echogenic halo denoting desmoplastic reaction and parenchymal distortion with right pathologically enlarged axillary lymph nodes. MRI images show right UOQ large irregular speculated mass with surrounding area of architecture distortion, eliciting intermediate SI with areas of high T2 and STIR signal intensity, and displaying rim enhancement in dynamic post-contrast series. MRI time/signal intensity curve of right UOQ mass lesion shows delayed peak of contrast uptake and plateau (type II). The pathology revealed TN invasive ductal carcinoma.
