Herein we present a 63-year-old male patient with a solid hepatic alveolar echinococcosis diagnosed by surgical biopsy. His liver lesion, which was infected, was drained by percutaneous catheterization. The lesion surprisingly disappeared completely after the treatment. The patient was followed-up without any symptoms for 20 months after the drainage. As alveolar echinococcosis of the liver behaves like a slow-growing liver cancer, the disappearance of our patient's lesion was a very unusual and rare outcome, which, to the best of our knowledge, has never been published in the literature.
