Caroli's Disease Combined with Colon Cancer and Polycystic Kidney Disease / 대한소화기내시경학회지

ABSTRACT

Caroli's disease is defined as a communication between congenital cystic dilatation of the bile duct and the biliary system. Caroli's disease accompanied with autosomal dominant polycystic kidney disease is a very rare finding and the differential diagnosis between Caroli's disease with polycystic kidney disease and a polycystic liver is very important. A 67-year-old male patient was admitted to our hospital for hematochezia, and he underwent hemodialysis for chronic renal failure due to his autosomal dominant polycystic kidney disease. On colonoscopy, ulcero-infiltrative tumor was observed in the sigmoid colon. It was diagnosed as adenocarcinoma on tissue biopsy. On abdominal computerized tomography and magnetic resonance cholangiopancreatography, a number of simple cysts was observed in both kidneys and we were able to identify the communication between the dilated intrahepatic ducts and the intrahepatic cystic lesions, and so we diagnosed this patient as having Caroli's disease.
