title: Radiological and pathological features of AIDS-related polypoid cholangitis.
abstract: A review of the radiographs obtained at ERCP from 31 patients with AIDS-related sclerosing cholangitis (ARSC) demonstrated intraluminal polypoidal defects within the common bile duct and larger intrahepatic ducts in eight cases (26%). The radiological features from this subgroup are described and correlated with the microbiological and histological findings from biopsy specimens including two patients who underwent post-mortem examination. At microscopy the polypoid lesions were demonstrated to consist of granulation tissue. The presence of these polyps did not adversely affect the prognosis nor were they associated with any particular infective agent. We propose recognizing the existence of this entity by the term AIDS-related polypoid cholangitis (ARPC).
