Liver Cyst Prevalence and Characteristics
General Population Prevalence
- Simple hepatic cysts occur in 2.5–18% of the population, making them a frequently encountered incidental finding on abdominal imaging, with prevalence increasing with age and a female predominance 1
- The prevalence of isolated polycystic liver disease (without kidney involvement) is much rarer at 1/10,000–1/158,000 1
Polycystic Liver Disease
- In patients with autosomal dominant polycystic kidney disease (ADPKD), liver cysts are present in >80% by age 30 years, representing the most frequent extrarenal manifestation 2
- Most people with ADPKD will not develop clinically symptomatic polycystic liver disease despite having liver cysts 3, 4
Clinical Significance and Detection
- Mucinous cystic neoplasms (MCNs), which carry malignancy risk, are rare, with an estimated prevalence <5% compared to simple hepatic cysts 1
- The increased detection of liver cysts is largely due to the widespread use of enhanced radiological imaging techniques, particularly ultrasound, CT, and MRI 1
Liver Cyst Prevalence and Characteristics
Cyst Types and Prevalence
- Mucinous Cystic Neoplasms (MCNs) carry a malignancy risk with transformation rates up to 30% 5
