CT findings of human Fasciola hepatica infection: case reports and review of the literature

Due to increasing rates of international travel, hepatic fascioliasis is appearing in nonendemic areas, where diagnosis can be difficult. We present two confirmed cases of hepatic fascioliasis in a nonendemic region. The purposes of this report are to discuss computed tomography (CT) findings of hepatic fascioliasis and to review the literature. While travel history is most important, characteristic findings of hypoattenuating tracts extending from liver capsule into the parenchyma on contrast-enhanced CT scan strongly suggest hepatic fascioliasis.
