When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Meningioma.
The exact cause of meningiomas remains largely mysterious to medical researchers.
The exact cause of meningiomas remains largely mysterious to medical researchers. These tumors develop when cells in the meninges begin dividing uncontrollably, but what triggers this abnormal growth is not fully understood. Think of it like a cellular copy machine that suddenly starts making too many copies without being told to stop.
Genetic factors play a role in some cases.
Genetic factors play a role in some cases. People with a rare genetic condition called neurofibromatosis type 2 have a much higher risk of developing multiple meningiomas. Additionally, certain genetic mutations in the meninges themselves can lead to tumor formation, though most people with meningiomas don't have any known genetic predisposition.
Hormones, particularly estrogen, appear to influence meningioma growth.
Hormones, particularly estrogen, appear to influence meningioma growth. This helps explain why women develop these tumors twice as often as men, and why some meningiomas grow larger during pregnancy or when taking hormone replacement therapy. Previous radiation exposure to the head, even from medical treatments received years earlier, can also increase the risk of developing a meningioma later in life.
Risk Factors
- Being female, especially middle-aged women
- Previous radiation therapy to the head or neck
- Neurofibromatosis type 2 genetic condition
- Age between 40 and 70 years
- Hormone replacement therapy use
- Pregnancy or multiple pregnancies
- Family history of meningiomas
- Previous head injury or trauma
- Breast cancer history
Diagnosis
How healthcare professionals diagnose Meningioma:
- 1
Diagnosing a meningioma typically begins when symptoms prompt a visit to the doctor, though many are discovered incidentally during brain scans for other reasons.
Diagnosing a meningioma typically begins when symptoms prompt a visit to the doctor, though many are discovered incidentally during brain scans for other reasons. The diagnostic journey usually starts with a thorough neurological examination, where the doctor checks reflexes, coordination, memory, and other brain functions. If a brain tumor is suspected, the next step is almost always magnetic resonance imaging (MRI).

MRI scans provide detailed pictures that can reveal a meningioma's size, exact location, and relationship to surrounding brain structures.
MRI scans provide detailed pictures that can reveal a meningioma's size, exact location, and relationship to surrounding brain structures. The scan often includes a contrast dye that makes the tumor appear brighter and more defined. CT scans may also be used, particularly to check if the tumor has caused any bone changes in the skull. These imaging tests can usually distinguish meningiomas from other types of brain tumors based on their characteristic appearance and location.

In most cases, imaging alone is sufficient for diagnosis, and a biopsy is not necessary before treatment.
In most cases, imaging alone is sufficient for diagnosis, and a biopsy is not necessary before treatment. However, if the tumor's appearance is unusual or if it's growing in an atypical pattern, a small tissue sample might be obtained during surgery. Additional tests might include angiography to examine blood vessels near the tumor, especially if surgery is being planned. The diagnostic process also involves determining the tumor's grade, which indicates how quickly it's likely to grow.
Complications
- Most meningiomas cause few complications, especially when they're small and discovered early.
- However, complications can arise depending on the tumor's size, location, and growth rate.
- The most common issues occur when a growing meningioma puts pressure on important brain structures, potentially affecting functions like vision, hearing, speech, or motor skills.
- Seizures represent another possible complication, though they can usually be well-controlled with medication.
- Surgical complications, while uncommon with modern techniques, can include infection, bleeding, or temporary worsening of neurological symptoms.
- Some people experience swelling around the surgical site that may temporarily affect brain function.
- Long-term complications from surgery are rare, but can include permanent changes in sensation, movement, or cognitive function, depending on the tumor's location.
- Recurrence after treatment is possible but uncommon, occurring in less than 10% of completely removed Grade I meningiomas, though higher-grade tumors have higher recurrence rates.
Prevention
- Preventing meningiomas is challenging because most cases occur without any identifiable preventable cause.
- Unlike some cancers linked to lifestyle choices, meningiomas seem to develop more from genetic and hormonal factors that are largely beyond our control.
- However, understanding the known risk factors can help people make informed decisions about certain medical treatments.
- The most actionable prevention strategy involves being cautious about unnecessary radiation exposure to the head and neck.
- While medical radiation for legitimate health reasons is generally worth the small increased risk, avoiding unnecessary CT scans or other radiation-based procedures makes sense.
- For women considering hormone replacement therapy, discussing the potential slightly increased risk of meningioma growth with their doctor can help inform treatment decisions.
- Since many meningiomas are discovered incidentally, maintaining regular healthcare and addressing persistent neurological symptoms promptly can lead to earlier detection if a tumor does develop.
- While this isn't prevention in the traditional sense, early detection often means more treatment options and better outcomes.
- People with neurofibromatosis type 2 or a family history of meningiomas should discuss appropriate screening schedules with their healthcare providers.
Treatment decisions for meningiomas depend heavily on several factors: the tumor's size and location, whether it's causing symptoms, how fast it's growing, and the patient's overall health.
Treatment decisions for meningiomas depend heavily on several factors: the tumor's size and location, whether it's causing symptoms, how fast it's growing, and the patient's overall health. Many small, asymptomatic meningiomas are simply monitored with regular MRI scans every 6 to 12 months. This "watch and wait" approach, called observation, is often the best choice for slow-growing tumors that aren't causing problems.
Surgery remains the primary treatment for meningiomas that are causing symptoms or growing significantly.
Surgery remains the primary treatment for meningiomas that are causing symptoms or growing significantly. Neurosurgeons aim to remove as much of the tumor as possible while preserving normal brain function. Complete removal is often achievable, especially for tumors in accessible locations. Modern surgical techniques include using intraoperative MRI and computer navigation systems to precisely locate and remove tumors while minimizing damage to healthy tissue.
Radiation therapy serves as an important alternative when surgery isn't possible or when some tumor remains after surgery.
Radiation therapy serves as an important alternative when surgery isn't possible or when some tumor remains after surgery. Stereotactic radiosurgery, despite its name, doesn't involve cutting - instead, it delivers precisely focused radiation beams to the tumor. This technique is particularly useful for smaller tumors in difficult-to-reach locations. Traditional radiation therapy delivered over several weeks may be used for larger tumors or those that have recurred.
Medications play a supportive role in meningioma treatment.
Medications play a supportive role in meningioma treatment. Anti-seizure drugs help control seizures if they occur, while corticosteroids can reduce brain swelling around the tumor. Research into targeted therapies and immunotherapy for aggressive or recurrent meningiomas is ongoing, offering hope for new treatment options in the future. Most people with successfully treated meningiomas can expect to return to normal activities within a few months of treatment.
Living With Meningioma
Living with a meningioma often means adapting to a new relationship with medical monitoring and learning to manage uncertainty. For those under observation, regular MRI scans become a routine part of life. Many people find it helpful to establish a schedule for scans and develop coping strategies for the anxiety that can accompany waiting for results. Keeping a symptom diary can help track any changes and provide valuable information to healthcare providers.
