Prognosis mainly depends on the type of infestation (ie, whether it is cystic [CE] or alveolar echinococcosis [AE]). In CE, the prognosis is generally good, and complete cure is possible with total surgical excision without spillage. Spillage occurs in 2%-25% of cases (depends on the location and surgeon's experience), and the operative mortality rate varies from 0.5%-4% for the same reasons.

In AE, the prognosis is much worse. Cure is only possible with early detection and complete surgical excision. In patients in whom the latter is not possible, the addition of long-term chemotherapy has decreased the 10-year mortality rates from 94% to 10%.
