title: Biliary wall calcification in Langerhans cell histiocytosis: report of two cases.
abstract: Langerhans cell histiocytosis (LCH) is a disorder of unknown pathogenesis affecting one or more organs (unifocal or disseminated form) due to clonal proliferation of Langerhans cells. Liver involvement is more frequent in the disseminated form and the radiological findings of end-stage liver disease due to LCH are similar to those of sclerosing cholangitis. We present the multidetector CT findings in two children with LCH liver involvement and the unique finding of calcification of the biliary wall.
