Tentorial meningioma

Tentorial meningiomas can be divided into incisural, falcotentorial, lateral, and posterior types based on their anatomical location, because surgical difficulty is related to the tumor region. The incisural type requires skull base approaches for radical removal. 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. Twenty-five meningiomas located at the tentorial notch were surgically treated between 1978 and 1993 at the Neurosurgical Department of Nordstadt Hospital in Hannover, Germany.

Tentorial meningiomas comprise 3-5% of the intracranial meningiomas. Different locations and sinus invasion require special surgical skills. Background: Tentorial meningiomas represent about 5% of intracranial meningiomas.

Tentorial meningiomas represent about 5% of intracranial meningiomas. 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.

Spinal Meningioma: Located in the spine, in some cases against the spinal cord. Suprasellar Meningioma: Located near the area of the skull where the pituitary gland is found. Tentorium Meningioma: Located near where the brain connects to the brainstem, an area known as the tentorium cerebelli.

Feb 10, 2021 At operation the tentorial meningioma, which did not compress either the fifth or the seventh cranial nerves directly, was totally removed via a

1, 2 Because of their critical relation to the neurovascular structures around the tentorial hiatus, microsurgical resection is challenging. Tentorial herniation is a serious symptom, especially since the brainstem is likely to be compressed as well if the intracranial pressure rises further. A common type of herniation is uncal herniation.

A major supply Tentorial meningiomas are relativily rare lesions which present difficult diagnostic and surgical problems. Despite the fact that tumors in this location represent less than 3% of all meningiomas, their frequent involvement with dural venous sinuses, deep venous structures, plus the brainstem and the cranial nerves, they have led to interest far exceeding their rate of occurance 16 . meningiomas are the most common and feature unusually plump cells. Fibroblastic meningiomas feature long, thin shaped cells. Transitional meningiomas contain both types of cells. Another system uses the terms benign, atypical and malignant (or anaplastic) to describe the overall grade of meningiomas. In this system, benign meningiomas At operation the tentorial meningioma, which did not compress either the fifth or the seventh cranial nerves directly, was totally removed via a suboccipital Patient was referred from other hospital with posterior fossa mass.

Tentorium Meningioma: Located near where the brain connects to the brainstem, an area known as the tentorium cerebelli. Diagnosis: Tentorial Mengioma Findings: Rounded enhancing mass located in the infratentorial region as demonstrated on above MR with contrast scans. Relatively homogeneously enhancing lesion is identified with moderate mass effect. Key Points: Tentorial meningiomas are relatively uncommon lesions located along the tentorium, adjacent to the cerebellum.
