What is a Hypo-dense mass?

A hypodense liver mass is an area of the liver that shows up as a different color on ultrasound or CT scan than the liver itself. It is not a diagnosis, but only an observation of the picture the radiologist took. It's often found "accidentally" while looking for something else, and doesn't need treatment but may need a follow-up picture in a few months. Your health care provider will combine this finding with the ohter information gathered from the history, physical, and lab tests to determine what this finding means for you.
