MRI scan of the patient’s brain shows a left extraaxial tumor at the sphenoid wing extending in the frontal and temporal lobe region.
 

Computer Navigation

Computer simulation and modeling was utilized for precise localization of tumor (green in the right lower pic, and outlined in red circle).

• He underwent orbitozygomatic craniotomy and surgical resection of this brain tumor using brain mapping, stereotactic and computer navigation, and intraoperative neurophysiological monitoring.
