Cystic echinococcosis is a chronic parasitic zoonosis of high prevalence in Chile. We report a clinical case of a 66-year-old man, domiciled in an urban area of the Maule Region, who presents skeletal muscle cystic echinococcosis. Consultation for pain, volume increase and left thigh fistula that gives out crystalline fluid. In the study with imaging techniques, multiple cystic lesions are identified in the sacral wing, iliac bone, soft tissues of the groin and left thigh. No cysts were evident in other organs. Serology Elisa IgG was positive Echinococcus granulosus. Surgical resection of soft tissue injuries. Combined antiparasitic therapy with albendazole and praziquantel was started, with good clinical response. Upon discontinuation of antiparasitic therapy at the initiative of the patient, symptoms are reinitiated.
