Primary Cyst Hydatidosis of Pelvis with Groin Pain and Limb: A Case Report

Echinococcosis may involve all organs of body; however, primary pelvic cyst hydatid involving bone with groin and anterior hip pain is very rare. We presented a case of extensive pelvic cyst hydatidosis involving bone without pathological fracture, in a 22-years-old man. First symtoms of patient was groin and anterior hip pain and limb. The diagnosis was made clinico-radiologically and the patient was cured with enbloc resection and filling bone cement. The patient was relieved completely one year after surgery. Cyst hydatid should be included in the differential diagnosis in patients with groin and anterior hip pain, although pelvic cyst hydatoid result in urinary, genital and abdomen problems. Much hydatid disease can be cure by administration of antihelminthic drugs, however, curettage and bone cementing is good choice in patient involving bone to eliminate recurrences and bone fracture.
