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.

OBJECTIVE: Even during the microsurgical era, tentorial meningiomas present a formidable surgical challenge when tumor involves critical neurovascular structures. We report our experience with tentorial meningioma with regard to clinical presentation, diagnostic …

13 The exact origin of the tumor may be recovered only during surgery. TENTORIAL MENINGIOMAS* By MANNIE M. SCHECHTER, M.D., LAWRENCE H.ZINGESSER, M.D., and ARTHUR ROSENBAUM, M.D. NEWYORK,NEWYORK ENINGIOMAS account forapproxi-mately 20pencent ofallintracranial tumors. InOlivecrona’s series, 8. per cent ofmeningiomas arose intheposterior fossa and just oven one-third ofposterior fossa meningiomas arose from the Tentorial meningiomas are rare tumors located along the surface of the tentorium cerebella in the brain.

Methods. The records of 27 patients with TMs were retrospectively reviewed for clinical presentation, neuroradiological evaluation, surgical treatment and long-term outcome. Tentorial meningiomas represent about 5% of intracranial meningiomas. This article reviews our recent institutional series of patients with tentorial meningiomas, proposes a simplified Tentorial meningiomas are a rare and heterogeneous group of tumors.[9,22] In the period reported on in this study, 454 meningiomas were operated upon at our institution; of these, some 7% were attached to the tentorium. Two other patients were diagnosed with tentorial meningiomas but declined surgical treatment and were followed with serial MRI. Tentorial meningiomas comprise 3-5% of the intracranial meningiomas.

Mar 22, 2017 We report the superior cerebellar artery as an unknown origin of this artery. We developed our strategy in a case of a tentorial meningioma mainly

Eight of the tumours were seen to extendboth supratentorially and infratentorially; the major growth, however, wasin one direction. Clinically, a Tentorial meningiomas are notorious for their critical location. Selection of a suitable approach that exposes the multicompartmental growth of tumor is important for a complete and safe resection. This paper discusses about various operative approaches and their overall surgical outcome.

Tentorial meningiomas are rare tumors located along the surface of the tentorium cerebella in the brain. These types of posterior fossa meningiomas can cause headaches, seizures, and difficulty walking.

Classification. Tentorial meningioma classification . Signs and symptoms of cranial hypertension are the most common Treatment. They tend to enclose, displace, or Tentorial meningiomas are those located under the surface of the tentorium cerebelli.

Meningioma is the most common type of tumor that forms in the head. Patients harboring a lateral tentorium meningioma (T6–T7 subgroup) usually present with headache, dizziness, and gait unsteadiness. 4,12 Clinical examination often reveals a gait ataxia and involvement of the VIIIth cranial nerve (CN). 4 It may be difficult to differentiate between lateral tentorial and suprameatal posterior petrosal meningiomas on clinical and radiologic grounds. 13 The exact origin of the tumor may be recovered only during surgery.

Selection of a suitable approach that exposes the multicompartmental growth of tumor is important for a complete and safe resection. This paper discusses about various operative approaches and their overall surgical outcome. • 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. Ipsilateral tentorial meningiomas, and ipsilateral and contralateral cerebellopontine (CP) angle tumors causing HFS have been described in the literature.,,, Here, we report an unusual case of huge tentorial meningioma presenting with contralateral HFS [Video].

This chapter is concerned with medial tentorial meningiomas that involve the inner ring of the tentorium.
