Reprint requests to: publications@acr.org Evaluation of the Symptomatic Male Breast mammography may obviate further unnecessary interventions for falsely presumed gynecomastia (eg, altering medications) [12]. Gynecomastia may be incidentally identified on chest CT [13]. Men with characteristic imaging findings of gynecomastia on CT do not benefit from further evaluation with mammography unless there is a suspicious clinical finding (eg, eccentric breast mass, nipple discharge, or axillary adenopathy) [13]. DBT In men with clinical findings consistent with gynecomastia or pseudogynecomastia, digital breast tomosynthesis (DBT) is not routinely indicated. When performed, gynecomastia demonstrates similar imaging characteristics on DBT compared to mammography [14,15]. US Breast In men with clinical findings consistent with gynecomastia or pseudogynecomastia, ultrasound (US) is not routinely indicated. When US is performed, gynecomastia may appear mass-like and demonstrate vascularity on color Doppler [16-18]. Comparison with the contralateral side may be helpful on real-time imaging, as synchronous bilateral breast carcinoma in males is rare.
