A 18-year-old pregnant woman noted a palpable mass in her left breast. On targeted ultrasonography, a circumscribed mass with low-level internal echoes and posterior enhancement was noted, as well as a focal echogenic area representing a fat plug (arrow) in this galactocele, which was aspirated to resolution.
