Hepatic Cysts in Korea: Prevalence, Incidence, and Risk Factors Based on a 5.8-Year Follow-up Health Screening Cohort

Background

Hepatic cysts are fluid-filled liver lesions that are mostly asymptomatic, but fewer than 15% of patients present clinically significant symptoms. Reported prevalence ranges from 2.5% to 71%, yet prior studies have been limited by small populations and incomplete assessment of risk factors. This study aimed to determine the prevalence, incidence, and risk factors using data from a large health screening cohort in Korea.
