Aims To elucidate whether breast imaging can predict final histologic diagnosis of lesions of uncertain malignant potential diagnosed at ultrasound core needle biopsy (CNB). Methods The imaging characteristics (mammography, ultrasound, and magnetic resonance imaging [MRI]) of lesions of uncertain malignant potential in the breast that were obtained by ultrasound CNB were retrospectively analyzed in 87 women. Radiologic characteristics of lesions were compared to definitive histopathologic findings. Results Out of 87 breast lesions of uncertain malignant potential, 27 (31%) were diagnosed as papillary lesions, 24 (28%) atypical ductal hyperplasia, 19 (22%) lobular intraepithelial neoplasia, 9 (10%) phyllodes tumors, 3 (3%) radial sclerosing lesions, and 5 (6%) unspecified lesions of uncertain malignant potential. The underestimation rate of malignancy at CNB based on the total number of lesions on final follow-up was 22%. Using multivariate logistic regression, Breast Imaging-Reporting and Data System (BI-RADS) score (odds ratio [OR] = 12.29, p = 0.027) and Göttingen MRI scoring system (OR = 8.1, p = 0.008) were found to be independent predictors of malignancy. Receiver operating characteristic analysis showed that Göttingen MRI score >3 provides a plausibly good cutoff value with sensitivity of 100 (95% confidence interval [CI] 74%-100%) and specificity of 76% (95% CI 61%-88%). Conclusions Lesions of uncertain malignant potential classified as BI-RADS 5 and Göttingen score 4 or higher are at significantly higher risk of harboring malignancy and therefore should be recommended for surgical excision.
