A case of chondrosarcoma originating within the postethmoidal and sphenoidal sinuses with intracranial invasion will be reported. The patient, a 54-year-old female, presented severe headaches and diminished visual acuity of the right eye. Angiographic findings showed both the left carotid artery to be completely occluded and the right inner carotid artery to be narrowed at the site of the carotid bifurcation. Computerized tomography scan findings showed a tumor, located mainly in the frontal base and temporal fossa, that had invaded the cranium through the skull base. Several tumor excisions were performed using a combined extranasal and transmaxillary approach. The diagnosis 'chondroma' was changed to 'chondrosarcoma' during autopsy.
