Liver Disease — Liver Cysts
Most simple cysts are benign — surveillance is often enough
Simple liver cysts are common and usually benign. Most cause no symptoms and are found incidentally on ultrasound or CT. Large, bleeding, infected, or complex (suspicious) cysts may need further tests and rarely intervention.

Figure summary
This educational figure shows: Liver cysts.
Key points
Simple cyst
Thin-walled, clear-fluid cyst. Asymptomatic lesions are observed. Very large cysts may cause fullness or pain.
- Key note inside
Complex / suspicious cyst
Thick wall, septa, solid areas, bleeding, or infection suspicion lead to MRI and further work-up. Distinguishing cystadenoma from cystadenocarcinoma can be critical.
When intervention is discussed
Symptomatic large cysts, infection, bleeding, or diagnostic uncertainty may lead to drainage or surgery options.
- Key note inside
Hydatid is different
Thick wall, septa, daughter cysts, or endemic exposure raise hydatid disease. “Just watch like a simple cyst” may be wrong — see the hydatid chapter. Blind aspiration is dangerous when hydatid is possible.
Frequently asked questions
Does a liver cyst mean cancer?
Most simple cysts do not. Complex features need proper imaging characterization first.
Should every cyst be drained?
No. Asymptomatic simple cysts are usually observed.
