Rationale and Objectives To propose grid coordinate marker placement for patients with suspicious ductogram findings occult on routine workup. To compare the success of marker placement and wire localization (WL) with ductogram-guided WL. Materials and Methods A retrospective search of radiology records identified all patients referred for ductography between January 2001 and May 2008. Results for 16 patients referred for ductogram-guided WL and 5 patients with grid coordinate marker placement at the time of ductography and subsequent WL were reviewed. Surgical pathology results and clinical follow-up were reviewed for concordance. Results Nine of 16 patients (56.3%) underwent successful ductogram-guided WL. Eight of nine patients had papillomas, one of which also had atypical ductal hyperplasia (ADH). One of nine patients had ectatic ducts with inspisated debris. Seven patients who failed ductogram-guided WL eventually underwent open surgical biopsy. Four of seven patients had papillomas, one of which also had lobular carcinoma in situ. Remaining patients had ADH (1/7) and fibrocystic changes with chronic inflammation (3/7). All five (100%) patients with grid coordinate marker placement underwent successful WL and marker excision. Pathology results included three papillomas, papillary intraductal hyperplasia, and fibrocystic change. Conclusion Grid coordinate marker placement at the time of abnormal ductogram provided an accurate method of localizing ductal abnormalities that are occult on routine workup, thus facilitating future WL. Marker placement obviated the need for repeat ductogram on the day of surgery and ensured surgical removal of the ductogram abnormality.
