Young patient, high risk, 31 years old. a Ultrasound gray scale image that displayed an oval-shaped solid mass with suspicious infiltrative presentation and irregular borders and accordingly was given as BI-RADS 4 category. b Pre-contrast T2-weigthed MR image that displayed lower outer solid breast mass (circle). c Post-contrast subtraction image (taken at 2 min.40 s, post-injection of contrast, circle) that showed suspicious early and heterogeneous contrast uptake of the left breast mass (arrow). According to the morphology descriptors of the MR images, the mass was irregular and showed intense contrast uptake; these criteria rendered the mass to be suspicious of malignancy (BI-RADS 4) and biopsy was requested. d The time/signal intensity curve showed type I pattern presented with early peak of the contrast uptake with a corresponding high signal intensity percentage of 96%. Examination of the removed specimen after surgery revealed an intracanalicular fibroadenoma surrounded with fibrofatty tissue with no evidence of malignancy
