What is Tentorial meningioma?
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.
How do you shrink a meningioma?
Since the vast majority of meningiomas are benign (noncancerous), they are most commonly treated with surgery. Total removal of a meningioma is preferred since it lessens the chances of the tumor returning. Sometimes radiation can help reduce the size of a meningioma.
What is Excision of meningioma?
The most common type of surgery to remove a meningioma is called a craniotomy. This procedure involves making an incision in the scalp and removing a piece of bone from the skull. The neurosurgeon can then access and remove the tumor, or as much of the tumor as possible without risk of severe damage to the brain.
What causes posterior fossa meningioma?
While we do not know what causes posterior fossa meningiomas, these tumors are often benign and slow-growing, arising from the meninges, or layers of tissue that cover the brain and spinal cord.
Why are surgical approaches important for tentorial meningiomas?
Background: 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.
How is the removal of a falcotentorial meningioma performed?
Selection of the suitable and anatomically favorable operative approach is key for safe and effective removal of falcotentorial meningiomas. Careful inspection of the preoperative images should identify the relationship of the tumor to the tentorium, splenium, internal cerebral veins, vein of Galen, and basal vein of Rosenthal.
How are meningiomas treated at Mount Sinai Hospital?
Meningiomas are a common type of brain tumor that develops slowly in the meninges, or the area that covers and protects the brain and spinal cord. Most meningiomas are benign and can vary greatly in size and location. Mount Sinai neurosurgeons and specialist teams are skilled at recognizing and treating various types of meningiomas.
Where are suprasellar meningiomas located in the brain?
Suprasellar meningiomas develop near the pituitary gland and optic nerve at the base of the skull. These types of meningiomas grow slowly and can cause severe visual impairment in one or both eyes. Tentorial meningiomas are rare tumors located along the surface of the tentorium cerebella in the brain.
