MLO and CC views of left breast mammogram show an oval shape homogeneous mass in upper inner quadrant which has relatively smooth and well-defined border. There is no microcalcification or architectural distortion. On ultrasound images the lesion is homogeneously hypoechoic with lobulated but distinct margins, measuring approximately 19*14mm.

Fibroadenomas are the most common well-defined solid masses seen on mammography. They are homogenous but frequently show large, coarse calcifications. They may have a lobulated contour, but there are usually only a few large lobulations. If a fibroadenoma is not calcified, it cannot be distinguished from a cyst by mammography. Sonography will allow characterization of fibroadenomas as solid hypoechoic masses. The peak age of patients with clinically detected fibroadenomas is 20 to 30 years; however, fibroadenomas are seen into the eighth decade. They rarely appear or grow after menopause.
