Petroclival meningiomas: remaining controversies in light of minimally invasive approaches

Meningiomas are usually benign lesions that account for 20 –25% of intracranial tumors, and 10% occur in the posterior fossa. Of these, 5–11% affect the petroclival region, accounting for 0.15% of intracranial masses overall [1,2]. Surgical resection of petroclival meningiomas remains challenging due to their depth and relationship to vital neurovascula r structures.
