Objective And Importance:
Excluding tumors of hematopoietic origin, osteosarcomas are the most common bone tumor, although involvement of the brain or cranial base is rare.
Clinical Presentation:
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.
Intervention:
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.
Conclusion:
The patient was alive and without evidence of disease 11 months after presentation but died shortly thereafter of complications related to adjuvant therapies.
