title: Polyarteritis nodosa presented as a dilatation of the intrahepatic bile duct.
abstract: Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis of small- and medium-sized arteries in multiorgan systems. PAN may affect the gastrointestinal tract in 14%-65% of patients, but rarely involves the biliary tract and liver. We describe a patient without underlying disease who was diagnosed with PAN during resection of the gallbladder and liver.
