Meningiomas are generally benign tumors that arise from the lining that surrounds the brain. Meningiomas are generally described according to the anatomic location at which they arise, and the symptoms that they produce typically are related to the parts of the brain that are impacted by the tumor. For instance, tumors that develop behind the eyes can cause vision issues, while tumors that develop in the area of the olfactory nerves can interfere with the sense of smell.
The terms to describe meningiomas include:
• Convexity meningiomas – These develop on the surface of the brain directly underneath the skull
• Skull base meningiomas – These develop in the bones at the bottom of the skull and at the back of the eyes
• Sphenoid wing meningiomas – These develop in the bones where the convexity meets the skull base
• Suprasellar meningiomas – These develop in the skull base near the optic nerves and pituitary gland
• Parasagittal and falcine meningiomas – Both of these develop in or on the thin layer of tissue that separates the two sides of the brain
• Intraventricular meningiomas – These develop inside the ventricular system where cerebrospinal fluid is produced
• Optic nerve sheath meningiomas – These develop on the optic nerve
• Olfactory groove meningiomas – These develop on the nerves that run from the brain to the nose
• Posterior fossa/petrous meningiomas – These develop the nerves on the underside of the brain
• Spinal meningiomas – These develop within the spinal canal and push on the spinal cord
• Foramen magnum meningiomas – These develop in the small opening through which the spinal cord connects to the brain
Because Moffitt Cancer Center is a leading destination for brain tumor treatment, the oncologists in our Neuro-Oncology Program have notable experience with all types of meningiomas that arise from all of the locations listed above, including ones that may require consideration of options beyond surgery alone.
