Osseous hydatidosis is a very uncommon disease which often recurs after treatment. There is no well-established effective method of management. Radical excision may produce serious mutilation and often fails to control the disease. We have used oral mebendazole as adjuvant treatment in four patients. Two also underwent radical excision, one had received limited excision elsewhere and the other did not have operative treatment. The patients who underwent radical excision and the other who did not have an operation became and remain free of symptoms and are serologically negative.A combination of excision and treatment with mebendazole may have a role in the management of this complex disease.
