Abstract
Materials and Methods:
The authors retrospectively analyzed 60 cases of stereotactic localization performed for lesions which were mammographically visible but not palpable. Each case was reviewed for chief complaint, indication of localization on a mammograph, location of the lesion, pathological diagnosis, and complications during and after the procedure.
Results:
Most patients(75%) had no specific complaint. Among the 60 cases, microcalcification, mass and combined lesions were found in 34(57%), 12(20%), and 14 cases(23%), respectively. The most common location of the lesion was the upper outer quadrant(29 cases). A histopathologic report was available in 56 of 60 cases. Among 43 benign cases(76.8%), fibrocystic disease was most common(38 cases, 67.9%), while among 13 malignant cases, ductal carcinoma was most common(9 cases, 16.1%). In four of 56 cases(7.1%), failure to remove the target lesion was identified. Retrospective analysis suggests that movement of the patient during the procedure is the most likely cause of failure. There were no major complications.

A. Stereograph shows clustered microcalcifications on right subareolar region. Note symmetry of hyperlucent area(open arrows) and radiopaque strip(arrows) on both sides, which represent fenestration in compression plate and edge of the plate respectively. B. Stereograph obtained after placing the needle with curved-wire. Needle tip is well located to the lesion. C. Specimen radiograph reveals clustered microcalcifications within excised specimen. Pathologic diagnosis was ductal carcinoma.
