Bilateral CC diagnostic mammogram. Images (A) and (B) demonstrate retro-areolar, flame-shaped, bilateral densities (yellow arrows), diagnostic of gynecomastia. However, in the outer left breast (B), there is a palpable triangular marker (orange arrow) overlaying a high density, irregular mass (red outline), eccentric to the nipple and atypical of gynecomastia, warranting further evaluation.CC, Craniocaudal.
