Abstract
A 49-year-old man presented with headache and cognitive difficulty. MRI demonstrated a meningioma in the falcotentorial region with compression of the internal cerebral veins, basal veins of Rosenthal, and vein of Galen. It was a removed via a left-sided occipital interhemispheric approach, performed with the patient in the lateral position. After tumor debulking and removal of its attachment to the tentorium and anterior falx, the tumor was resected. All venous structures were preserved. The video demonstrates the technical nuances and strategy for removal of tumors in a region with complicated venous anatomy that must be preserved.
