Example of ductal carcinoma in situ after silicone injection in the breast. A 44-year-old woman who received silicone injection had a suspicious lesion in the left breast on magnetic resonance imaging (MRI) screening. (A) Silicone granulomas showing high signal intensities on the inversion recovery MRI with chemically selective water suppression. (B) Sagittal T1-weighted subtracted dynamic image of the left breast showing irregular, speculated, heterogeneous enhancing mass, which was categorized into American College of Radiology Breast Imaging Reporting and Data System category 5. (C) Dynamic time-intensity curves of the lesion showing an initial fast uptake followed by a delayed washout (type III). (D) Sagittal T1-weighted subtracted dynamic image of the left breast showing the obturator tip (arrow) within the mass. Histologic analysis demonstrated ductal carcinoma in situ.
