Question: 1 / 400

What is a common imaging characteristic of liver cysts?

Hyperechoic and well-defined

Anechoic with thin walls

Liver cysts typically present as anechoic lesions, meaning they do not produce any echoes on ultrasound. This characteristic arises from the fluid-filled nature of cysts, which allows ultrasound waves to pass through without reflection. The walls of these cysts are usually thin and well-defined, making them appear as clear, smooth boundaries within the liver tissue. This well-defined and anechoic appearance is crucial for distinguishing liver cysts from other potential liver lesions, such as tumors or abscesses, which often demonstrate different echogenic properties.

The clarity of anechoic cysts in ultrasound imaging helps in confirming their benign nature and in making accurate diagnoses, facilitating proper management and follow-up.
