Multiple comet tail artifacts in the liver: a case of congenital hepatic fibrosis showing unusual biliary appearance.

Congenital hepatic fibrosis (CHF) is a form of autosomal recessive polycystic kidney disease. Because of the common underlying pathophysiology of ductal plate malformation, CHF can be accompanied by an abnormal biliary appearance, which is characterized by a saccular or fusiform dilatation of the bile ducts. We encountered the case of a 35-year-old man suffering from CHF concomitant with esophageal varices, which were treated by endoscopic sclerotherapy.
