Abstract
Petroclival (PC) meningiomas are difficult-to-treat, deep-seated skull base lesions arising from the petroclival synchondrosis with close proximity to vital neurovascular structures. Their management has undergone paradigm shifts over the past few decades that span from radical resection to more tailored surgical decompression that offers deficit-free survival. These changes have been enabled by the advent of modern microneurosurgical skull base techniques, better understanding of the surgical anatomy, and availability of intraoperative neurophysiological monitoring and efficacious adjuvant therapy option such as stereotactic radiosurgery (SRS) in the armamentarium of modern skull base neurosurgeon. This chapter reviews the natural history, clinical presentation, preoperative evaluation, decision-making, surgical approaches, role of SRS, and treatment outcomes in the era of multimodality management of PC meningiomas.
