Giant cell tumour of the petrous bone.

ABSTRACT

Giant cell tumours (GCT) are rare in the skull bones. In the cranium the sphenoid bone is the most common site. The petrous bone is a very uncommon location for such tumours. The chance location of GCT at the base of the skull makes total surgery difficult and hazardous. A case of GCT of the petrous bone is presented. The clinical course in the patient and role of primary radiotherapy in GCT in such an unusual site is discussed.
