A 16-year-old teenager was referred by an endocrinologist to a public clinic for an ultrasound scan, including of the mammary glands, with complaints of enlargement of one of the glands.
According to the teenager, he had previously had a similar situation with another gland, which then returned to normal.
On ultrasound in the projection of the enlarged mammary gland, a pronounced layer of glandular tissue (gynecomastia) is visualized, without increased blood flow at CFM.
"Gynecomastia refers to an enlargement of the male breast caused by benign proliferation of the glands ducts and stromal components including fat. It is the most common form of breast swelling seen in adolescent males. During pubertal development, gynecomastia can develop as a result of transient relative imbalances between androgens and estrogens. Pubertal gynecomastia is self-limited in 75 to 90% of adolescents and regresses over 1 to 3 years."
