Cryptosporidial infection is one of the recognised causes of diarrhoea in AIDS patients. It may also produce biliary tract disease. Fifteen out of 250 (6%) AIDS patients seen at our hospital had Cryptosporidial enteritis and five of the 15 (2% total) had clinical evidence of biliary tract disease. The radiological findings in these five patients are presented. Ultrasound examination of all five patients showed abnormalities in the biliary tree; five had dilatation and irregularity of the intra- and extrahepatic bile ducts with focal strictures, four had gall-bladder wall thickening, two had thickening of the common bile duct wall, two patients showed areas of increased reflectivity in the periductal regions of the liver and two had pancreatic duct dilatation. ERCP in one patient confirmed the ultrasound findings and Cryptosporidium oocytes were isolated from the collected bile. We conclude that Cryptosporidial infection in the biliary tree can produce distinctive appearances on ultrasound which may well obviate the need for more invasive investigations such as ERCP.
