Meningiomas
These types of tumors are typically non-cancerous and grow slowly. We help patients with clear guidance, tailored treatments and support.
Slow, non-cancerous tumors
Meningiomas are typically non-cancerous (benign), slow-growing tumors that arise from the membranes (meninges) surrounding the brain and spinal cord. These tumors are relatively common — comprising 30 percent of all primary brain tumors — and are most often seen in middle-aged women. Meningiomas can appear in any portion of the lining of the brain and spinal cord. A small minority of meningiomas are cancerous (malignant).
Types of meningiomas
Convexity and parasagittal meningioma
Tumors that arise from the membranes (meninges) over the side and top of the skull. Some of these tumors grow into or compress the superior sagittal sinus, a large vein coursing over the center of the head.
Falcine meningiomas
Tumors that form in or next to a very thin extension of membrane (falx cerebri) that courses between the two sides of the brain.
Olfactory groove meningiomas
Tumors that arise from the membranes at the bottom of the skull, above the nose. They can cause only loss of smell or more significant neurologic impacts like personality changes and cognitive difficulties.
Sphenoid wing meningiomas
Tumors that arise from the membranes over the bone that spans from the side of the head behind the eye toward the center where the optic nerves and pituitary gland are located. Depending on location, they can cause seizures, brain disturbance, visual loss, double vision or numbness of the face.
Skull base meningiomas
Tumors arising from the meninges over the bones at the bottom of the skull that cover the orbits, nose and sinuses. They also extend toward the back of the skull base, covering the middle ear, pituitary gland, nasopharynx and spinal cord. These often require a multidisciplinary team approach.
Posterior fossa and petrous meningiomas
Tumors that form on the underside of the brain at the skull base. Depending on location, symptoms can include facial sensory loss, hearing problems and double vision. They can also affect the tongue, swallowing, vocal cords, movement, coordination and vital body functions.
Suprasellar meningiomas
Tumors that arise from the membranes at the base of the skull near the pituitary gland and the optic nerves and can cause visual impairment in one or both eyes and, in some cases, pituitary hormone dysfunction.
Brain tumor clinical trials
We offer patients hope through a robust clinical trial research program to discover the next generation of brain tumor treatments.
