The sonographic findings in four patients with gynecomastia are presented. The sonographic appearance is correlated with previously described pathologic and x-ray mammographic findings. Sonographically, early, focal gynecomastia appears as a triangular, hypoechoic mass in the retroareolar area. As gynecomastia become diffuse, it results in a hyperechoic increase in the glandular parenchyma. Awareness of the various etiologies and variations in appearance is important for the sonographic diagnosis of gynecomastia.
本文展示了4例男性乳腺增生患者的超声检查结果。超声表现与先前描述的病理及乳腺钼靶X线检查结果相关。在超声检查中，早期局灶性男性乳腺增生表现为乳晕后区的三角形低回声肿块。随着男性乳腺增生发展为弥漫性，腺实质会出现高回声增强。了解男性乳腺增生的各种病因及外观变化对于超声诊断至关重要。
