There are several types of meningioma, with each one developing in a different part of the brain and producing different symptoms. For instance, tumors that develop behind the eyes can cause vision issues, while tumors that develop on the olfactory nerves can interfere with the sense of smell. As a result, physicians usually evaluate a patient’s symptoms to determine which type of meningioma might be present; from there, imaging scans and lab tests can be used to confirm the diagnosis.
Meningioma types 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 behind the eyes
- Suprasellar meningiomas – These develop in the skull base near the optic gland and pituitary nerve
- 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 on the nerves on the underside of the brain
- Spinal meningiomas – These develop around 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 meningioma, from the more common (intraventricular, parasagittal, sphenoid wing and convexity meningiomas) to the rarer (spinal and posterior fossa meningiomas).
A referral is not required to make an appointment at Moffitt. To learn more about the various types of meningioma and the possible treatments for each, call 1-888-MOFFITT or submit a new patient registration form online.
