Vanishing Lesion During US-Guided Core Needle Biopsy: Can We Exclude Malignancy?

Abstract

PurposeWe analyzed the pathology of vanishing lesion during core needle biopsy of breast to ascertain whether this finding can be a radiologic clue to exclude malignancy or not.Material & Methods548 women underwent US-guided core needle biopsy between January 2009 and February 2011 and 98 vanishing lesions were detected in 91 patients. Automated gun biopsy with 14G needle (Magnum ®) were used and vanishing lesion was defined as nonvisualization or volume loss more than 90% after needle passage with less than 3 times. Before biopsy, 81 lesions (82.6%) were classified as BIRADS category 4a, 12 lesions (12.2%) showed significant interval change of size and shape on follow-up study and 5 lesions (5.1%) were category 3 with clinical suspicions.Results548 women underwent US-guided core needle biopsy between January 2009 and February 2011 and 98 vanishing lesions were detected in 91 patients.
