Hydatidosis of the pelvis and hip.

We report eight cases of osseous hydatidosis involving the pelvis and hip. All patients were treated by curettage and albendazole therapy. In three cases, in which only the ilium was involved, the outcome was satisfactory. The remaining patients required several debridement procedures in combination with chemotherapy and two developed chronic lesions. We conclude that treatment for this condition is difficult and when the osseous involvement is extensive the prognosis is poor.
