Abstract:
Falcotentorial meningiomas are uncommon tumors that account for 1%-2% of all intracranial meningiomas. They arise at the junction of the falx cerebri and tentorium, from the entry of the vein of Galen posteriorly to the confluence of venous sinuses. Treatment for these tumors depends on patient and tumor factors. Tumor factors include size of the tumor, patency of the straight sinus, and the amount of tumor above and/or below the tentorium. This chapter reviews the clinical presentation, imaging features, treatment options, and results.
