Cyberknife stereotactic radiosurgery and denosumab for giant cell tumour of the skull base: Case report.

Giant cell tumours (GCT) of the skull is a rare entity with only small number of cases reported in literature and optimal treatment is yet to be determined. These tumours have shown high recurrence rates after incomplete surgery, usually occurring during the first year. Even with new surgical techniques a complete resection in skull base tumours is not always possible without functional compromise.
