Osteosarcoma of the temporal fossa with hemorrhagic presentation: case report.
OBJECTIVE
Excluding tumors of hematopoietic origin, osteosarcomas are the most common bone tumor, although involvement of the brain or cranial base is rare.


METHODS
A 16-year-old girl with an osteosarcoma of the temporal fossa presented with an intracerebral hemorrhage. The management strategy of this lesion, including the operative interventions, is described.


METHODS
Several modes of treatment were undertaken, including radical resection of the cranial base lesion and excision of the cavernous sinus after a cervical internal carotid artery-to-middle cerebral artery vein bypass graft.


CONCLUSIONS
The patient was alive and without evidence of disease 11 months after presentation but died shortly thereafter of complications related to adjuvant therapies.
