[Comparative imaging of HIV associated diseases of the hepatobiliary system in computerized tomography and cholangiography].

With the incidence of AIDS being on the rise, diagnostic work-up of hepatobiliary disease in these patients is of increasing interest. 57 x-ray cholangiograms and computed tomographic studies of 13 AIDS-patients with clinical signs of cholangitis were reviewed. Nine patients had abnormal cholangiographic findings. Computed tomography of 8 patients revealed hepatobiliary disease in six cases. Of three patients with cholangiograms reflecting bile duct dilatation of neoplastic aetiology, CT was required in two for definite diagnosis. Cholangiography is the method of choice for diagnosing AIDS-associated cholangitis, whereas computed tomography compares favourably in depicting neoplastic disease of the hepatobiliary system. Follow-up of AIDS-associated cholangitis usually delineates unchanged radiologic findings.
