The authors present an uncommon case of portal venous gas and contrast opacification that occured during endoscopic retrograde cholangiopancreatography. This report demonstrates that portal vein cannulation may be a source of confusion because the guided wire trajectory inside the portal vein may be similar to that of the biliary, and a contrast washout/opacified portal vein may be misinterpreted as an incompletely filled bile duct.
