[Computerized tomography of liver in alveolar echinococcosis treated with albendazole]

Eleven cases of alveolar echinococcosis were examined by using computerized tomographic (CT) scanning of liver 2-7 years after long-term continuous albendazole therapy. In seven cases the hepatic lesion was almost completely calcified and cured in three cases incomplete calcification of the peripheral margin of the hepatic lesion was observed. CT scanning of the remaining in effective case showed active lesion with heterogenous hypodense areas in the liver without calcification on the peripheral margin. Long-term continuous albendazole therapy can be lethal to the parasite.
