Multiple findings in this breast ultrasound

Another strange case. There are multiple findings in the breasts in this sonographic study. 

1st:

Both breasts showed prominent mammary ducts. Without proper history, the sonographic appearances are bizarre 😳 to say the least 🙄. 

The reason for dilated mammary ducts is:

She's lactating. 

2nd finding:

The above ultrasound image showed what looked like a hypoechoic mass. But it's pretty much posteriorly placed. Also rotate the transducer. It's elongated. 

Answer: it's a costal cartilage. A normal finding. 

3rd finding: this is not normal 😐:

The ultrasound images above show an anechoic mass lesion and it's pretty large. 

A large simple cyst. 

Here's another ultrasound image:

A simple cyst is no big deal. So long as it doesn't get complicated with hemorrhagic changes or infection 😕. Now infection can cause a breast abscess. 

The prominent mammary ducts are also seen to the right of the ultrasound image. 

4th finding:

A moderately large mass, but this one is hypoechoic and not anechoic. That means it is a solid mass. It's oval and well defined. 

Non vascular. These are typical of only one lesion: fibroadenoma breast 🙄. 

Final diagnosis:

Fibroadenoma breast with breast cyst in lactating breasts.
