Right hepatic artery pseudoaneurysm ruptured into the gallbladder demonstrated by magnetic resonance angiography.
Rupture of a right hepatic artery pseudoaneurysm into the gallbladder is very rare. We demonstrated a 20-mm dumbbell-shaped pseudoaneurysm in the gallbladder lumen by using contrast-enhanced magnetic resonance angiography in a 73-year-old man with acute right upper abdominal pain. Inflammation of the gallbladder caused by calculous cholecystitis, which leads to biliary leakage and erodes the right hepatic artery, could have been the cause.
