A 52-year old woman was admitted to the hospital because of upper abdo
minal pain and hematemesis. Laboratory parameters showed marked choles
tasis. Endoscopic retrograde cholangiopancreatography (ERCP) lead to t
he diagnosis of hemobilia. CT-scan and angiography revealed an aneurys
m of the cystic artery as the cause of hemobilia. Cholecystectomy was
performed because of concomitant cholecystitis. Anatomical examination
confirmed clinical diagnosis.
