Mirizzi syndrome (hepatic duct obstruction).

The Mirizzi syndrome is an uncommon cause of obstructive jaundice. In 1948, Mirizzi characterized a syndrome in which common hepatic duct obstruction occurs because of impacted stones in the gallbladder neck or cystic duct. The authors report a case demonstrating this syndrome. They discuss the radiographic features and report the features found on a computed tomographic cholangiogram that have not been previously described. Computed tomography-cholangiography may be helpful in evaluating patients with suspected Mirizzi syndrome.
