What Is a Liver Cyst?

Liver cysts are often detected incidentally on US/CT/MRI. The majority are simple benign fluid-filled structures and need no specific treatment. Some larger cysts cause pain, fullness, nausea or compression symptoms. Hydatid cysts and other more complex cystic lesions require different approaches. This page summarises types, follow-up and surgical indications.

Quick Answer

Liver cysts are fluid-filled, mostly benign structures. Most simple cysts are asymptomatic and only observed. Large, painful, infected or parasitic (hydatid) cysts may require treatment, based on cyst type, size, location, symptoms and overall health.

Types of cysts

  • Simple (congenital) liver cyst
  • Polycystic liver disease
  • Hydatid cyst (parasitic)
  • Rare cysts such as cystadenoma
  • Secondary cysts (e.g. post-traumatic)

Symptoms

  • Usually asymptomatic
  • Right upper abdominal fullness in large cysts
  • Nausea, indigestion
  • Occasional pain
  • Fever and severe pain in infected cysts

Diagnosis

Ultrasound is the most common screening tool. CT or MRI is often needed to characterise the cyst. Serology may be requested when hydatid disease is suspected.

Treatment options

Small simple cysts are observed. Large, painful or infected cysts may need interventional or surgical treatment. Hydatid cysts follow dedicated protocols.

Frequently Asked Questions

Usually not — follow-up is sufficient. Rapid growth, pain or infection prompts re-evaluation.
