Multiple Choice

Polycystic liver disease is most commonly associated with which condition?

Polycystic liver disease most often runs with autosomal dominant polycystic kidney disease. In ADPKD, mutations in PKD1 or PKD2 disrupt polycystin function in biliary epithelial cells, leading to the development of multiple hepatic cysts. These liver cysts are the common extrarenal manifestation in adults with ADPKD and can cause hepatomegaly or discomfort, though many patients remain asymptomatic. By contrast, autosomal recessive polycystic kidney disease usually presents with congenital hepatic fibrosis and portal hypertension rather than widespread liver cysts, so it’s not the typical association. Fatty liver disease and acute viral hepatitis don’t create true polycystic liver changes.
