Pictorial Review of Male Breast Disease

Purpose of Review Many processes in the male breast are similar to those encountered in female patients, with a few notable differences. While the majority of male breast pathology is benign, a working knowledge of varying imaging presentations of both benign and malignant pathology is necessary to guide appropriate management. The focus of this review is to highlight the classic mammographic and sonographic appearances of benign and malignant pathologies in the male breast. Recent findings Mammography is the initial modality of choice for symptomatic male patients who are 25 years of age or older. In patients younger than 25, however, ultrasound should be performed first. Screening mammography for the general male population is not currently widely recommended due to the low prevalence of breast cancer in men. Additionally, although no current guidelines exist regarding the utilization of breast magnetic resonance imaging (MRI) in men, it can be used as an adjunct imaging modality for treatment planning in patients with breast cancer. Summary Mammography and ultrasound are the mainstay imaging modalities for evaluating the symptomatic male breast. Core needle biopsy can be performed in cases of suspicious findings.
