Hydatidosis of the pelvic bone: case report and review of the literature.

The authors report three cases of pelvic bone hydatidosis: two men and a woman aged from 25 to 42 years. The lesions were extensive: In two cases, they extended to the entire hemipelvis, and in one case, the extension was to the sacrum, which makes it difficult to carry out a radical surgery. In two cases, computed tomography was evocative and allowed for the completion of a local and precise checkup for a patient through MRI. At the therapeutic level, the first patient was treated by curettage and sterilization with oxygenated water followed by medical treatment, but with recurrence few months later. The second patient was put only under medical treatment because of the extent of the lesions, allowing therefore for clinical and radiological stabilization. Concerning the last patient, she benefitted from the resection of the femoral head and the right iliac wing followed by a medical treatment. The evolution was favorable with a three-year recession. The actual treatment of the osseous echinococcosis would be a combination of albendazole and surgery.
