Caroli's disease in three siblings

Abstract

Three sisters with cystic dilatation of the intrahepatic bile ducts (Caroli's disease) are reported. The index case, a 41-year-old woman with remittent high fever and right upper quadrant abdominal pain, was diagnosed as Caroli's disease with hepatic lithiasis and cholangitis based on findings of ultrasonography, computed tomography and endoscopic retrograde cholangiography. Her two older sisters were also examined and found to have the same disease without clinical symptoms. Their symptoms, locations of the dilated ducts and complications all varied. The hereditary mode of Caroli's disease in 13 families (32 cases) reported in the world literature including our study was examined. While Caroli's disease is thought to be an autosomal recessive disease, a conclusion on the hereditary mode of transmission could not be made in this study because of an insufficient investigation of family members, especially the parents.
