Purpose: To evaluate the upgrade rate of ultrasonography (US)-guided core-needle biopsy(CNB) of the breast for a pure mucocele-like lesion (MLL), to evaluate the clinical and radiologicfeatures, and to correlate the image-pathologic features further on to guide the management ofMLL. Methods: Between January 2003 and February 2013, 14-gauge US-guided CNB was performedin 18,111 cases. Thirty-two cases associated with MLL were identified, and five cases of MLLsassociated with breast carcinoma or with other high-risk breast lesions (i.e., atypical ductalhyperplasia [ADH], papillary lesions, lobular carcinoma in situ , and radial scar complex) wereexcluded. Among these 27 pure MLLs, 21 cases with surgical or vacuum-assisted excision (VAE)pathology were included in our study. Medical records, mammograms, and ultrasonograms werereviewed for the clinical and radiologic features of the cases. Results: Among the 21 cases with pure MLLs at CNB, the final pathology showed a 0%proportion of cases upgraded to malignancy. All the 21 cases with either surgical or VAEpathology were benign MLLs including three cases of focal involvement of ADH (14.3%). Thecommon features were mammographic features of microcalcifications that were round in shapeand had a grouped distribution. The US features included oval shape, circumscribed margin,parallel orientation, complex solid and cystic echo pattern, no posterior feature, and complexsolid and cystic echoic masses. The predominant Breast Imaging Reporting and Data System (BIRADS)category was 4A. All the lesions showed image-pathologic concordance. Conclusion: For pure MLL on US-guided CNB with image-pathologic concordance, close imagingfollow-up might be considered instead of surgical excision.
