title: Giant-cell tumor of the skull base.
abstract: Giant cell tumors are uncommon primary bone tumors. They primarily occur in the long bones. Giant cell tumors are extremely rare in the skull and head and neck. When it does occur, the maxilla and mandible are the common sites to be involved. We described two cases of giant cell tumor in the temporal bone. In the noncontrast enhanced CT, the lesion presents as a soft tissue density mass with expansion of the bone. The bony cortex is usually intact. The adjacent soft tissues and cerebral parenchyma show no infiltration or edema. The post contrast scan reveals homogenous enhancement of the mass.
