Abstract
- Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited renal disease. Polycystic liver disease is commonly observed in ADPKD but rarely has it been associated with a choledochal cyst. We report a case of a choledochal cyst with ADPKD in a 60-year-old female patient with ADPKD and concomitant chronic renal failure who was admitted because of acute deterioration of kidney function due to poor oral intake. There was no history of a biliary disorder and her kidney function recovered promptly after fluid replacement. Non-enhanced computed tomography was performed to evaluate ADPKD and revealed numerous cysts in both kidneys and liver. It also showed fusiform dilatation of the extrahepatic bile ducts, a finding indicative of a choledochal cyst. Liver function was within the normal range and there was no evidence of extrahepatic biliary obstruction. Magnetic resonance cholangiopancreatography confirmed the diagnosis of a type I choledochal cyst combined with ADPKD.
