What is a Meningioma?
A meningioma is a brain tumor that comes from the meninges. These are the protective layers around the brain and spinal cord. Most meningiomas are benign, making up 85-90% of cases. The rest are atypical or malignant.
These tumors usually happen to people aged 40 to 70. They are more common in women.
Types of Meningioma
Meningiomas come in 15 different types, as the WHO classifies them. Convexity meningiomas are the most common, making up almost 20% of cases. Other types, like Cavernous sinus meningiomas, can cause double vision and facial pain.
Skull base and spinal meningiomas are also types. They pose unique challenges because of where they are.
Meningioma Grading
Meningiomas are graded from I to III based on their growth and aggressiveness. Grade I tumors are slow-growing and low-grade. Grades II and III are more aggressive and have a higher chance of coming back.
Meningiomas are complex brain tumors with many types and grades. Each type needs its own care plan. Knowing the specifics of each meningioma subtype is key to effective treatment.
Symptoms of Meningioma
Meningiomas are the most common brain tumors. They can cause different symptoms based on where and how big they are. These tumors are usually benign, making up 90% of all meningiomas. They can be cured if removed surgically. Even a small meningioma can cause symptoms as it grows and presses on nearby brain tissue or nerves.
The most common symptoms include headaches, vision changes, seizures, numbness or weakness in the arms or legs, speech difficulties, memory loss, and hearing loss. Symptoms can vary based on the meningioma’s location:
- Convexity meningioma: Personality changes, hearing loss, vertigo
- Sphenoid wing meningioma: Loss of facial sensation, blurred vision
- Suprasellar meningioma: Blurred, double or patchy vision
- Parasagittal and falcine meningioma: Problems with logic or reasoning, memory loss
- Intraventricular meningioma: Unusual feeling of pressure within the head
- Olfactory groove meningioma: Loss of sense of smell, loss of vision
- Optic nerve sheath meningioma: Gradual loss of vision, color blindness
- Posterior fossa/petrous meningioma: Loss of facial control, loss of hearing
- Spinal meningioma: Back pain, pain that radiates through the arms or legs
- Foramen magnum meningioma: Difficulty walking, loss of fine motor skills
It’s important for a doctor to carefully check a patient’s symptoms to diagnose meningioma correctly. Symptoms can start slowly and last a long time before the tumor is found. Finding and treating meningioma early can help patients get better.
Meningioma Type | Specific Symptoms |
|---|---|
Convexity meningioma | Personality changes, hearing loss, vertigo |
Sphenoid wing meningioma | Loss of facial sensation, blurred vision |
Suprasellar meningioma | Blurred, double or patchy vision |
Parasagittal and falcine meningioma | Problems with logic or reasoning, memory loss |
Intraventricular meningioma | Unusual feeling of pressure within the head |
Olfactory groove meningioma | Loss of sense of smell, loss of vision |
Optic nerve sheath meningioma | Gradual loss of vision, color blindness |
Posterior fossa/petrous meningioma | Loss of facial control, loss of hearing |

“Early recognition and treatment of meningioma can lead to better outcomes for patients.”
Causes and Risk Factors
The exact cause of meningiomas, the most common brain tumor, is still a mystery. But, researchers have found some risk factors that might help them grow.
Radiation Exposure
Getting too much radiation, like from old cancer treatments, is a big risk factor. Studies show that getting radiation can lead to meningiomas. Kids who get radiation on their heads are more likely to get these tumors 10 to 15 years later.
Genetic Predisposition
Some genetic disorders, like neurofibromatosis type 2 (NF2), raise the risk of meningiomas. Most brain tumor patients don’t have a family history. But, if they do, it might mean they’re more likely to get tumors, especially if they’re young.
Also, having allergies or epilepsy might increase the risk of getting meningiomas. Some research looked into if cell phones cause brain tumors. But, the results are still not clear.
Knowing what causes meningiomas is key to finding them early and treating them well.
Diagnosis of Meningioma
Meningiomas are the most common brain tumors in the central nervous system. They are usually found through imaging tests. MRI and CT scans show detailed brain images, helping doctors spot tumors.
These tests are the first step in finding meningiomas. They grow slowly and can be mistaken for other health issues.
Doctors also do a neurological exam to check for changes in how you feel or think. Sometimes, a biopsy is needed to confirm the diagnosis and rule out other tumors. This helps doctors understand the tumor’s size, location, and growth rate for the best treatment plan.
It’s key to know that meningiomas are the most common brain tumors. But, there are rarer, more aggressive types like atypical and anaplastic meningiomas. These grow faster and are more likely to come back, needing more detailed evaluation and treatment.
Diagnosing meningioma involves a detailed look at your medical history, a neurological exam, and advanced imaging tests. This helps doctors figure out the best way to manage the tumor and any symptoms.
Meningioma Treatment Options
Meningioma is a brain tumor that needs a treatment plan just for you. The treatment depends on the tumor’s size, location, and type. It also depends on your health and what you prefer.
Observation
For small, harmless meningiomas, watching and waiting might be the best choice. Your doctor will check the tumor often with imaging tests. This way, you avoid the risks of more serious treatments.
Surgery
Surgery is the main treatment for most meningiomas. The goal is to remove as much of the tumor as possible safely. Sometimes, the tumor’s location or size makes surgery hard or not safe.
Radiation Therapy
Radiation therapy is used alone or with surgery for aggressive or coming-back meningiomas. There are different types of radiation therapy. They aim to shrink the tumor. About 50% of patients see improvement with radiation therapy.
Your treatment plan will be made just for you. Your healthcare team will help decide the best treatment. It’s key to talk about all options with your doctor. This way, you can make a choice that’s right for you.
Complications and Side Effects
Treatment for meningioma, like surgery or radiation, has risks and side effects. It’s key for patients to know these to choose their care wisely.
Possible Complications of Meningioma Surgery
Surgery for meningioma can cause brain swelling, nerve injuries, and fluid buildup. About 20% of people might get seizures afterward, but medicine can help.
Possible Side Effects of Radiation Therapy
Radiation therapy can lead to side effects like skin reactions, tiredness, and memory changes. Hair loss happens during treatment but grows back in a few months. Fatigue is common, especially in the last weeks of treatment.
But, some effects, like memory problems, can last forever. It’s important to talk to doctors about the risks and benefits of each treatment.
“Radiation therapy is often recommended after surgery to prevent tumor recurrence, particularly if the tumor was not completely removed during surgery.”
In some cases, watching the tumor closely might be the best choice. This is for tumors that were fully removed or for older people at risk of side effects.
Meningioma and Its Impact
Meningiomas, even though they are usually not cancerous, can still greatly affect a person’s life and brain. They are the most common brain tumors, making up 37.6% of all primary central nervous system tumors in the U.S.. In 2019, it’s estimated that 33,560 cases of meningioma occurred in the U.S, with an incidence rate of 8.6 per 100,000 people. Most people are diagnosed with meningiomas when they are 66 years old, and they are more common in women than men.
A meningioma can press on important nerves and the brain, leading to serious symptoms. These symptoms can affect thinking, vision, hearing, speech, and movement. Meningiomas can greatly impact a person’s quality of life, independence, and brain function.
While many meningiomas can be treated, the effects of the tumor and its treatment can be hard to deal with. Atypical meningiomas, which make up 18% of cases, have more tissue and cell abnormalities and are more likely to come back. Also, 1.7% of meningiomas are malignant, which is a bigger threat to patients.
Things like radiation from dental X-rays and genetic disorders like NF2 can raise the risk of getting meningiomas. Hormones may also play a role in their development.
“The impact of a meningioma can be life-changing, affecting a person’s physical, cognitive, and emotional well-being. Managing the long-term effects requires a multidisciplinary approach and support from healthcare professionals and loved ones.”
It’s important to tackle the challenges meningiomas bring to ensure patients’ quality of life and brain function.
