Autosomal dominant polycystic liver disease(ADPLD)refers to a condition characterized by the presence of numerous cholangiocytes-lined and fluid-filled cysts in the liver and the absence of polycystic kidney disease.1 Although patients with ADPLD may be asymptomatic,some patients suffer from abdominal pain,gastroesophageal reflux,and nausea,because of hepatomegaly.
