title: Mirizzi syndrome associated with hepatic artery pseudoaneurysm: a case report.
abstract: BACKGROUND
  This is the first case report of Mirizzi syndrome associated with hepatic artery pseudoaneurysm.
  
  
  METHODS
  A 54-year-old man presented with painful obstructive jaundice and weight loss. Computed tomography showed a hilar mass in the liver. Following an episode of haemobilia, angiography demonstrated a pseudoaneurysm of a branch of the right hepatic artery that was embolised. At surgery, a gallstone causing Mirizzi type II syndrome was found to be responsible for the biliary obstruction and a necrotic inflammatory mass and haematoma were found to be extending into the liver. The mass was debrided and drained, the obstructing stones removed and the bile duct drained with a t-tube. The patient made a full recovery.
  
  
  CONCLUSIONS
  This case highlights another situation where there may be difficulty in differentiating Mirizzi syndrome from biliary tract cancer.
