Torcular meningioma are stated to be located in the posterior cranial fossa attached to the confluence of sinuses with or without sinus invasion. • Meningiomas of the posterior cranial fossa is about 9% of all intracranial meningiomas • Tentorial meningiomas is about 30% of the posterior fossa meningiomas • First described by Andral in 1833 • Reviewing the deep venous system and venous drainage of the temporal lobe is the cardinal step when planning for the subtemporal and petrosal approach.

Tentorial meningiomas remain a formidable surgical challenge and, as the authors point out, are of great importance to all neurosurgeons. The authors' series is one of the largest, if not the largest, documented series of purely tentorial meningiomas, given that petroclival meningiomas were not included. Tentorial meningiomas comprise 3%of the total number of meningiomas seen at the New York Neurological Institute during the period analysed. Nineteen of the tumours were in women and five werein men. Eight of the tumours were seen to extendboth supratentorially and infratentorially; the major growth, however, wasin one direction. Clinically, a The approach from below was reserved for meningiomas with subtentorial involvement only. In meningiomas with both supra- and subtentorial growth, a supratentorial bone flap was combined with a suboccipital craniectomy using a retromastoid incision.
