Caroli's disease and congenital hepatic fibrosis associated with polycystic kidney disease. A case presenting with acute focal bacterial nephritis.
Congenital cystic dilatation of the intrahepatic biliary ducts (Caroli's disease), until recently, has been infrequently recognized. It is often associated with autosomal recessive polycystic kidney disease (ARPKD) and congenital hepatic fibrosis (CHF). We hereby report a case with Caroli's disease, polycystic kidney disease (PKD), and CHF: This 24-year-old female patient initially presented with acute bacterial nephritis (ABN). Renal ultrasonography revealed bilateral enlarged kidneys with multiple cysts. Because her parents showed no renal cyst on ultrasonographic examination, she received further studies. Abdominal ultrasonography showed cystic dilatation of the biliary tree. Computed tomography (CT) with meglumine lotroxinate (biliscopin) infusion study and hepatobiliary scintigraphy confirmed the diagnosis of Caroli's disease. Liver biopsy revealed CHF: The radiographic and scintigraphic pictures are hereby illustrated and CT with biliscopin infusion study is emphasized. We conclude that if radiologic evidence of renal cystic lesions is absent in the parents of patients with PKD, the coexistence of Caroli's disease and CHF should be considered. The clinical pictures of ABN in this patient are also discussed. As far as we know, this is the first reported case of ABN in a patient with PKD and Caroli's disease, and it showed good response to antibiotic therapy.
