Toxocariasis is a helminozoonosis caused by the infection of a human host by the larva of Toxocara canis and Toxocara catis, which are common nematodes in dogs and cats, and occurs more frequently in school age children. Toxocariasis shows variable clinical manifestations including hepatomegaly, bronchial asthma, uveitis, central nervous system symptoms with peripheral eosinophilia and an increased total serum IgE level. However a hepatic abscess caused by toxocara infection in adults is rare. We experienced a case of heavy alcoholic patients with a hepatic eosinophilic abscess caused by toxocara infestation, which was confirmed by microscopic examination of liver biopsy, enzyme-linked immunosorbent assay test, abdominal CT and the ultrasonography findings.
