Choledochocele demonstrated on percutaneous cholangiography: a patient with acute fulminant pancreatitis.

A patient with a choledochocele associated with development of acute fulminant pancreatitis is presented. Treatment had been severely compromised by this rare anomaly before it was identified by percutaneous cholangiography. Because it is potentially curable with surgery, identification of the lesion by percutaneous or intravenous cholangiography has important clinical significance.
