[Pseudotumor of the bile duct: its diagnosis by fine-needle percutaneous transhepatic cholangiography].

Three patients with jaundice are presented. One was erroneously diagnosed as a biliary tumor because of the image in the percutaneous transhepatic cholangiography. When he was operated upon, it was found a chronic pancreatitis. Two other patients exhibited in the first sequences of the percutaneous transhepatic cholangiography an obstruction of the common hepatic duct; this diagnosis was corrected rotating the patients 360 degrees on the X-ray table. With this procedure the existence of choledocolithiasis was demonstrated. Finally, the author presents the case of a patient in whom some cholangiographic sequences induced a diagnostic error, because of the scant opaque media injected.
