Hydatid disease of the pelvis and the femur. A case report.

We report a case of left-sided extended pelvic infestation of hydatid disease. The destruction of the hip joint, os pubis, larger parts of os ileum and the femoral head made pelvic resection and prosthetic replacement necessary. Recurrence of a hydatid cyst 5 years later in the left groin originating in the femur was treated with a second femoral resection and total hip replacement. Because of instability, the pelvic replacement also had to be changed to a custom-made CAD replacement. This surgical procedure was combined with chemotherapy by mebendazole. The need for radical resection in osseal hydatid disease is discussed.
