A giant cell tumor of the cranial base treated by stereotactic radiosurgery
Eun-Young Kim, Judith A. Murovic, Iris C. Gibbs, Lawrence M. Shuer, and Steven D. Chang

Giant cell tumors (GCTs) developing from the cranial bones are rare. Occurrence of these tumors in the vicinity of eloquent areas precludes complete excision. Fractionated external beam radiotherapy (FEBRT) has been used for those cases, but with inconsistent outcomes. The authors report a case of a patient with a GCT involving the left occiput which was successfully treated by CyberKnife stereotactic radiosurgery (CK RS). There was improvement in the neurological deficit and occipital pain without adjunctive treatment. This is the first report of stereotactic radiosurgery (SRS) adopted as a primary treatment modality for a cranial GCT.
