Meningiomas are typically benign (non-cancerous), slow-growing tumors that originate from arachnoidal cells, cells that make up a membrane that surrounds the brain and spinal cord. While slow growing, they can produce serious symptoms if left untreated, including headaches, hearing loss, facial problems and seizures. Posterior fossa and petroclival meningiomas are located on the underside of the brain, which makes them difficult to treat. Meningiomas in these locations may affect the trigeminal nerve (which may cause a feeling of abnormal sensations in the face), the vestibulocochlear nerve (which can cause hearing\/balance abnormalities) and the facial nerve (which results in facial weakness).<\/p>\n\n\n\n

Posterior fossa or petroclival meningiomas are diagnosed using imaging studies such as CT and MRI scans. If the tumors are slow growing and not causing any neurological symptoms, serial MRI imaging to monitor growth is an option. Because posterior fossa and petroclival meningiomas are located on the underside of the brain, surgical removal is complex. When indicated, such procedures require a team of surgeons, including a neurotologist and neurosurgeon. Stereotactic radiation therapy may also be an option for some patients.<\/p>\n\n\n\n
