Imaging the Male Breast

Purpose of Review: In this article, we review the clinical and imaging features of a variety of benign and malignant processes of the male breast, with focus on more common entities and those with specific imaging characteristics that may improve diagnostic accuracy. Recent Findings: We emphasize utilization of appropriate imaging modalities according to the age-based protocols provided by the American College of Radiology Appropriateness Criteria in the evaluation of the symptomatic male breast (Mainiero et al., J Am Coll Radiol 12:678–682, 2015). Summary: Based on review of the current literature, we discuss the risk factors, clinical and imaging features, and treatment of male breast cancer, focusing on any gender differences.
