Curettage and radiotherapy of giant cell tumour of the sacrum: a case report with a 10-year follow-up.

A case report of a 53-year-old woman with giant cell tumour of the sacrum is presented. Initial curettage was performed through a posterior approach and the patient was relieved of pain and discharged. However, 6 months later the patient was readmitted with a tumour that had progressed towards the L5 vertebra. A further curettage followed by adjuvant radiotherapy resulted in successful reduction of the tumour. Ten years after the operation, there was no recurrence or metastasis.
