Polyarteritis nodosa is a necrotizing vasculitis involving predominantly small and medium sized arteries,which may affect various organs, especially heart and kidney. In autopsy series, gallbladder involvement is foundin 10∼40% of cases. Rarely, it presents initially as acute cholecystitis, clinically. We report a case ofpolyarteritis nodosa initially presented as an acute acalculous hemorrhagic cholecystitis, which showed thickenedgallbladder wall and characteristic nondependent and nonlayering intraluminal echoes on ultrasonogram, and waspathologically diagnosed.
