Breast Imaging Clip Migration after 11-gauge Vacuum-assisted Stereotactic Biopsy: Case Report1 Liane E. Philpotts, MD and Carol H. Lee, MD 1 From the Department of Radiology, Yale University School of Medicine, 333 Cedar St, PO Box 208042, New Haven, CT 06520. Address correspondence to L.E.P. (e-mail: philpotts@biomed.med.yale.edu). A 68-year-old woman underwent stereotactic biopsy of a small cluster of calcifications. The postbiopsy mammograms showed the biopsy-marking clip to be located correctly at the biopsy site. Follow-up mammograms 1 year later showed that the clip migrated to another quadrant of the breast. Findings in this case demonstrate that at long-term follow-up a biopsy-marking clip may not be accurately marking the biopsy site. © RSNA, 2002 (Radiology 2002;222:794-796.) © RSNA, 2002 Remember we are NOT Doctors and have NO medical training.
