Giant Cell Tumor of the Sphenoid with Clivus Extension in a Pediatric Patient

Abstract

We present a case of giant cell tumor of the clivus in a pediatric patient. The case is very interesting because this benign tumor is generally located in the epiphysis of long bones, and only 1% is found in the cranial vault and the base of skull. The sphenoid bone and the petrous portion of the temporal bone are the most commonly affected cranial locations, probably due to their endochondral ossification.
