GONZALEZ-CARBAJAL PASCUAL, Miguel et al. Imagenología y fasciolasis de vías biliares: reporte de 4 casos. Rev. gastroenterol. Perú [online]. 2001, vol.21, n.3, pp.234-238. ISSN 1022-5129.

Fasciolasis is a cosmopolitan parasitic disease. The development of some diagnostic methods in imaging such as ultrasonography (US) and endoscopic retrograde Cholangio pancrea tography (ERCP),have given the possibility of detecting the presence of the parasite in the gall-bladder and in the extrahepatic biliary tract. Four cases of Fasciolasis in the biliary tract are presented, in which the ultrasonographics findings suggested a diagnosis of Fasciolasis which was later confirmed by a biliary drainage and/or stool culture. When there is no clinical evidence of parasitism, ultrasonography may help to assume the presence of parasite. The ERCP has the possibility to confirm the localization of the trematode in the extrahepatic biliary tract. Biliary tract Fasciolasis may present as a colestatic syndrome.
