Abstract

A 49-year-old man with chronic hepatitis B receiving treatment with entecavir visited a hospital with a complaint of abdominal pain. Computed tomography (CT) showed 2 liver tumors, each measuring 1cm in diameter, 1 in segment 7 and 1 in segment 4. Magnetic resonance imaging (MRI) showed a hypervascular tumor in segment 7 that appeared in a site different from that seen on CT. The liver tumor in segment 4 was not detected by MRI. Two months later, MRI showed a new liver tumor in segment 7/6 and that the liver tumor in segment 7 had increased to 2cm in diameter;blood tests showed eosinophilia. Enzyme-linked immunosorbent assay showed a high serum Toxocara antibody. The patient was diagnosed as having hepatic toxocariasis and was treated with albendazole for 8 weeks. After treatment, MRI showed that the liver tumors disappeared. Eosinophilia, multiple lesions, and the disappearance of the tumors were characteristic findings of visceral larva migrans.
