A 34-year-old woman with history of bilateral saline implants, invasive ductal carcinoma of the right breast, and suspicious left breast calcifications was referred for left breast lymphoscintigraphy before bilateral mastectomy. A total of 3.2 mCi of 99mTc-filtered sulfur colloid was administered with 3 subdermal injections in the superior, lateral, and inferior periareolar left breast in the late afternoon preceding the day of surgery. Imaging identified radiotracer uptake within a dense, circular area deep to the injection sites within the left breast, compatible with implant puncture and radiotracer administration within the indwelling breast implant.
