[Cerebellopontine Angle Meningioma].

Cerebellopontine (CP) angle meningiomas are surgically challenging because of their deep-seated location and proximity to the cranial nerves and vessels. Surgical approaches suitable for treating these tumors are described in detail in this article. CP angle meningiomas can be classified into six subtypes based on the tumor attachment location: 1)petrotentrial, 2)anterior petrous, 3)posterior petrous, 4)petroclival, 5)inferior petroclival or jugular tubercle, and 6)pure clival meningioma. The suitable approach for each subtype is described.
