Benign Fibroadenoma on Ultrasound

IMAGING FINDINGS: ​

​Single ultrasound image demonstrates an oval, circumscribed hypoechoic mass. The mass is wider than tall and does not demonstrate any suspicious features.

WHY IT MATTERS:

1. Benign fibroadenomas are the most common solid mass within the breast. As a radiologist you need to be familiar with the imaging characteristics.
2. Benign features on ultrasound include oval shape, circumscribed margins, wider than tall or parallel orientation.
