Multiple pelvic and thigh hydatid cyst: a case report.

Bone cystic echinococcosis is rare disease and its management remain difficult to treat due to frequent recurrences, related to certain locations such as proximal femur and ilium, where radical surgery is difficult to achieve. Medical therapy using Mebendazol can be an ultimate way to insure stabilization and remission of the parasitosis. We present a case of a 37-year-old male who had complaints of pain in left hip and limp four years after surgical management of pertrochanteric fracture of his right lower limb.
