[Up-dated progress in diagnosis and treatment of echinococcosis].

Diagnostic proces and choice of optimal management of cystic echinococcosis have to be related to the natural history of the parasite. The early and the late stages of invasion require a careful differential diagnosis with non-parasitic diseases. These are also the stages that many not require surgery. Chemotherapy, PAIR and "wait and observe approach" are alternative ways of cystic echinococcosis management. Em-18 WB test has a good diagnostic value in alveolar echinococcosis. Management of alveolar echinococcosis is based on radical surgery, prolonged chemotherapy and long-term observation.
