title: Peribiliary cysts mistaken for a biliary dilatation in a cirrhosis patient.
abstract: Peribiliary cysts are common in patients with chronic liver disease. Ambiguous imaging features and association with cirrhosis-induced hyperbilirubinemia may lead to misdiagnose an obstructive jaundice. Magnetic resonance cholangiopancreatography (MRCP) may be a useful sequence by showing small cystic structures with a specific periportal distribution on both sides of the portal veins, which do not communicate with the biliary ducts. These abnormalities may be recognized in order to avoid unnecessary endoscopic retrograde cholangiography.
