Figure 3: 55-year-old with left bloody nipple discharge status postductal excision which revealed a 1 cm noninvasive papillary carcinoma with positive margins. Postoperative MRI demonstrated a suspicious 5 mm focus of enhancement close to the excision site which needed to be included in the surgical re-excision. Due to small size of lesion, and lack of correlate on mammogram and ultrasound, an magnetic resonance imaging guided clip placement was performed. (a) Postcontrast axial sequence from the postoperative diagnostic breast magnetic resonance imaging demonstrating a suspicious 5 mm focus of enhancement (arrow) close to the excision site in the medial inferior left breast. (b) Sagittal image from the precontrast sequence demonstrates the grid to be well positioned with the postsurgical region (arrow) included in the field of view and within the grid. (c) Axial postcontrast sequence with a medial grid in place demonstrates the enhancing mass (arrow) abutting the skin to be well positioned within the grid. The mass appears closer to the skin compared to the diagnostic magnetic resonance imaging due to compression from the medial grid. (d) Postprocedure magnetic resonance imaging demonstrating the clip (arrow) to be well positioned within the enhancing mass. (e) The clip was subsequently localized with a radioactive seed using a digital technique. Postlocalization mammogram demonstrating the seed to be in close proximity to the biopsy clip.
