In this series, the curative effect was good without any death, allergic reaction and implantation. Conclusion The cystic lesion of liver should be considered as liver hydatidosis and Casoni test, indirect hemagglutination, together with CT and B-us examination can be used to comfirm the diagnosis though no clinical symptoms and history of inhabitancy in epidemic area presented.
