[Six cases of petroclival meningiomas with main tumor site of the free tentorial rim--so-called tentorium notch meningiomas].

Petroclival meningiomas especially petroclival meningiomas with prevalent expansion to the tentorial notch are extreme rare. In the present paper we report about six patients with petroclival meningiomas of the tentorial notch who were operated in four years. The particular anatomical relations and the resulting symptoms and the neurosurgical procedures are discussed in detail. The postoperative state of the six patients is without exception satisfactory.
