Liver Transplantation for Diffuse Form of Caroli Disease with Chronic Hepatitis B: A Case Report

Abstract

Caroli disease (CD) is a congenital disease of the intrahepatic biliary system, which manifests as cystic dilatation of the intrahepatic bile ducts. The disease has a low incidence and atypical clinical manifestations; therefore, it can be easily misdiagnosed. Hepatitis B infection is a viral infection that affects liver cells, leading to degeneration, necrosis, and regeneration of the cells and formation of false lobules, and ultimately nodular cirrhosis, which can lead to liver dysfunction and liver failure. Herein, we report a case of decompensated liver cirrhosis because of a diffuse form of CD, which was misdiagnosed because of long-term hepatitis B virus (HBV) infection. Finally, orthotopic liver transplantation (OLT) was performed, and the patient was cured. We believe that this congenital factor combined with HBV infection accelerated cirrhosis progression in this patient. This transplant was carried out in accordance with the Helsinki Congress and the Declaration of Istanbul.
