Localization of non palpable breast lesions

Eighty patients underwent localization for non-palpable breast lesions. The indication for performing a localizing procedure before the excision biopsy were suspicious or grouped microcalcifications, stellate shadows with or without microcalcifications, rounded opacities larger than 1 cm of distorted breast parenchyma. The highest incidence of malignancy was found in patients with grouped microcalcifications. The procedure for localization of a non-palpable breast lesion is well-described and the various localizing needles were far also described. The advantages and disadvantages of the different needles were discussed. The only complication was a vasovagal attack which was of no clinical significance
