A rare localization of hydatid disease is within soft parts. Herein we present a retrospective study of 7 cases with isolated and primary hydatid cyst in peripheral muscles. The preferred population was rural man (85.7%) with mean age of 43.4%, how was consulted for swelling and a very slowly growing mass, and it has grown last 3 months; without any other physical finding at his systemic examination. Thigh is reported to be involved 6 out of 7, 4 at the lodge adductors. Imaging tests and immunological reactions are very helpful in making preoperative diagnosis but histology confirmed that.
