[Dynamic observation on ultrasonographic image during chemotherapy of hepatic cystic echinococcosis and a proposal for ultrasonic classification].

Objective: To submit a proposal for the classification of ultrasonographic image in patients with hepatic cystic echinococcosis, on the basis of characteristic and distribution of ultrasonic image of hydatid cysts in cases and systematic observation on dynamic changes of sonographic image under treatment with emulsion albendazole and in relation to clinical efficacy.

Methods: The ultrasonic image of 645 cysts in 497 cases with liver cystic echinococcosis was classified. The distribution of different types of image in patients was analyzed.
