Right side SOM. Axial CT scan before and after surgery. A 58-year-old female patient operated via the pterional approach. The tumor was extending through the bone and under the temporalis muscle. The invaded pathological bone flap was removed. The tumor was found to invade the dura and the temporal lobe. Anterior clinoidectomy was performed, with drilling of the optic canal. Gross total resection was achieved (Simpson grade I). The dura was resected and reconstructed using a temporalis fascia graft. Regression of the existing proptosis was noted in the immediate postoperative period
