A 38-year-old rice farmer visited a hospital for abdominal pain. Computed tomography (CT) showed a liver tumor and magnetic resonance imaging (MRI) revealed a hypovascular tumor, both in segment 4. Thus, he was diagnosed with liver abscess. Ten days later, CT showed a new liver tumor in segment 8, but the size of the liver tumor in segment 4 had decreased. He was suspected with parasitic disease because of eosinophilia. Enzyme-linked immunosorbent assay showed a high level of serum Fasciola antibody. The patient was diagnosed with fascioliasis and was treated with triclabendazole. Post-treatment, CT revealed that the liver tumors had shrunk. Eosinophilia and multiple lesions were characteristic findings of parasitic disease.
