Gallbladder ulcer eroding the cystic artery: a rare cause of hemobilia.

We report a hemorrhage from an eroded cystic artery in an ulcer of an inflamed calcolous gallbladder. Bleeding from the papilla was observed at side-view endoscopy. Echo endoscopy and contrast-enhanced computed tomography suggested a gallbladder bleeding. A clear-cut diagnosis was made by selective angiography, followed by embolization of the cystic artery, hence stopping the hemorrhage. Cystic artery bleeding into the gallbladder is rare. The diagnostic and therapeutic implications are discussed.
