Spectrum of Various Male Breast Lesions: Pictorial Review with Radiologic-Pathologic Correlation

Most men referred for breast imaging have palpable lumps. Most lesions that are evaluated are benign, and malignancy is less common. Although there are characteristic imaging features of malignancy, substantial overlap is presented between benign and malignancy. Therefore, other imaging modalities are increasingly being used for accurate evaluation. We report on various male breast lesions using ultrasonography, mammography, computed tomography, and positron emission tomography-computed tomography. Pathognomonic histologic findings of each case are also provided.
