Computer tomography of liver in alveolar echinococcosis treated with albendazole

Fourteen cases of alveolar echinococcosis were examined by computed tomographic (CT) scanning of the liver, including 3 cases before treatment and 11 cases 2.0-7.5 years after long-term continuous albendazole therapy. In 7 cases the hepatic lesions were almost completely calcified and cured, while in 3 cases incomplete calcification of the peripheral margin of the hepatic lesions was observed. CT scanning of the one uncured case and the 3 cases before treatment showed active lesions with heterogeneous hypodense areas in the liver without calcification on the peripheral margin. Long-term continuous albendazole therapy can result in parasitological cure with death of the parasite.
