[Radiologic aspects of noncalculous inflammation of the biliary tract in AIDS].

Six cases of non-lithiasic cholecystitis and 7 cases of inflammatory cholangitis caused by cryptosporidium and/or cytomegalovirus infections have been studied in HIV-1 + patients. All patients were examined with ultrasound and 5 with computed tomography (CT). The appearance is the same as that described for non-lithiasic cholecystitis (pain when the ultrasound probe is applied, thickened gallbladder wall) and sclerosing cholangitis (dilatation and/or stenosis of the bile duct, thickened gallbladder wall). The ultrasound or CT examination of HIV + patients with gallbladder involvement is sufficient to guide treatment when a thickened gallbladder wall is demonstrated. On the other hand, bile duct opacification is the only method allowing the accurate assessment of the extent of lesions in cholangitis, on which the indication for eventual sphincterotomy is based.
