Radial scar is an idiopathic entity that represents a diagnostic challenge due to its similarity with breast cancer radiologically. The screening mammography of a 65-year-old female patient revealed asymmetrical parenchymal distortion. Breast ultrasound showed minor cysts and magnetic resonance imaging detected adjacent nodules with no contrast enhancement. Then, the lesion was excised with the help of mammography-guided needle localization method. Pathologic diagnosis was moderate ductal epithelial hyperplasia and radial scar. Although radial scar is a benign breast lesion, it mimics breast cancer mammographically and sonographically.
