Ultrasound mammography for male breast enlargement.

Fourteen men referred for ultrasound evaluation of breast enlargement had ultrasound mammography using water path techniques. Gynecomastia, both the localized type and the diffuse type, could be differentiated from the normal soft tissues of the chest wall on the B-scans. Among nine cases of men who underwent excision, there were six cases of gynecomastia, two lipomas, and one biopsy revealed normal subcutaneous tissue. The ultrasound B-scan images are correlated with the histologic findings in these nine cases. Ultrasound mammography using water path techniques is a useful imaging examination for male breast enlargement.
