A liver cyst is a fluid-filled sac that forms on or within the liver. Also known as a hepatic cyst, most are simple cysts that leave surrounding tissue normal. They're typically benign and are discovered incidentally during imaging tests like ultrasound, CT or MRI.
Small liver cysts often cause no symptoms. When symptoms do occur, they may include:
Liver cysts can arise from several factors:

Most liver cysts are benign and cause no symptoms. However, parasitic cysts (e.g., from Echinococcus) or very large cysts can lead to complications and require prompt evaluation.
The term "hepatic cyst" refers to a fluid-filled sac within the liver tissue, commonly identified on imaging studies like ultrasound, CT, or MRI.
Diagnosis involves blood tests and imaging exams-ultrasound, CT scan, or MRI-to confirm the cyst's size, type (simple, parasitic, etc.), and any associated issues.
The ICD-10 code for a non-parasitic liver cyst is K76.89.
Small simple cysts typically don't cause pain. If a cyst grows large enough to stretch the liver capsule or press on adjacent organs, you may experience mild discomfort, bloating, or fullness.
Liver cysts can arise from developmental ductal abnormalities, parasitic infections (like Echinococcus), prior liver trauma, or inherited conditions such as polycystic liver disease. Often, the exact cause remains unknown.
Most simple hepatic cysts require no treatment and are monitored with periodic imaging. Intervention-drainage, sclerotherapy, or surgery-is reserved for cysts that grow, become painful, or cause complications.
Up to 5% of adults have simple liver cysts by age 50. Most are discovered incidentally during imaging for other reasons and remain asymptomatic.
Treatment options include:
Consult a gastroenterologist if you have persistent right-upper quadrant pain, bloating, or if follow-up imaging shows cyst enlargement or unusual features. Early assessment ensures proper management and peace of mind.
