[Acalculous cholangitis and cholecystitis in two AIDS patients].

Acalculous cholangitis and cholecystitis may occur in the course of AIDS. The symptoms are always the same: pain in the right upper quadrant, fever, nausea, vomiting, anorexia and diarrhoea, associated with biochemical signs of cholestasis, often without jaundice. Morphological explorations show thickening of the gallbladder wall and dilatation of the extrahepatic bile ducts, sometimes associated with stenosis of the major duodenal papilla and dilatation of the intrahepatic bile ducts.
