The authors present the case of a patient with relapsing parasitic cyst of the liver and a parasitic cyst of the lungs. The patient was treated by surgery. The cystectomy of the echinococcus cyst in the liver was made in the first stage and subsequently a resection of the lung tissue containing another echinococcus cyst was made. Pharmacological therapy by the anti-helmintic drug albendazol was a part of the treatment. There were no complications during both surgical interventions and the subsequent treatment. In the scolocidal liquid of the liver cyst, echinococcus organisms were diagnosed by microscopy and documented by photography.
