MRI appearances of fascioliasis complicating liver iron overload.
A case of hepatic fascioliasis with an unusual appearance on MRI due to liver iron overload is presented. The diagnosis of fascioliasis was based on positive serological tests and the presence of eggs in the bile. Hepatic lesions of fascioliasis exhibited hyperintense signals on T1 weighted images as well as proton density and T2 weighted images. Histological study of biopsy specimens from the lesions showed central necrosis and peripheral fibrosis with inflammatory cells including eosinophils. Abundant iron deposition in hepatocytes and Kupffer cells was found in specimens from the surrounding liver. These findings suggested that this appearance on MR images was probably due to a decrease in signal intensity in surrounding liver.
