The cholangiographic and pancreatographic appearances of the acquired
immunodeficiency syndrome (AIDS) associated cholangitis were evaluated
in 26 patients. Twenty-four patients were diagnosed by retrograde cho
langiography or endoscopic cholangiopancreatography (ERC or ERCP). One
patient was diagnosed by T-tube cholangiography and another patient b
y transhepatic cholangiography. The radiographic findings ranged from
intrahepatic ductal abnormalities with or without involvement of the e
xtrahepatic biliary tree (eight patients) to irregularities and strict
ures involving the ampulla of Vater or the intrapancreatic portion of
the common bile duct (CBD) with proximal dilatation (18 patients). Sig
nificant strictures involving the juxta-ampullary pancreatic duct were
identified in six of 12 patients. Twenty-one of the 26 patients had a
ssociated infections which included: Cryptosporidium (CS), Mycobacteri
um avium intracellulare (MAI), cytomegalovirus (CMV), Microsporidium (
MSP), and Isospora (ISP). Three patients were operated upon for acute
acalculous cholecystitis. In each instance, organisms were identified
in both the bile duct and the inflamed gall bladder.
