Meningioma
A meningioma is a tumor that develops from the meninges, the protective layers of tissue surrounding the brain and spinal cord. Most meningiomas are slow-growing and non-cancerous, but their size and location can cause pressure on the brain or nearby nerves, leading to neurological symptoms.
Dr. Garga Basu provides comprehensive evaluation and personalised treatment planning for patients with meningioma. Depending on the tumor’s size, location, growth, symptoms, and overall health of the patient, treatment may involve regular monitoring, surgery, radiation therapy, or a combination of approaches.
Types of Meningioma
Meningiomas can occur in different areas around the brain and spinal cord. They may be classified based on their location and microscopic characteristics.
Common locations include:
- Convexity Meningioma: Develops on the surface of the brain beneath the skull.
- Skull Base Meningioma: Occurs at the base of the skull and may be located close to important nerves and blood vessels.
- Parasagittal Meningioma: Develops near the midline of the brain and may affect areas responsible for movement.
- Sphenoid Wing Meningioma: Develops near the sphenoid bone and may affect the optic nerve or other important structures.
- Spinal Meningioma: Develops around the spinal cord and may cause pain, weakness, or difficulty walking.
Meningiomas are also graded according to their microscopic characteristics. Most are Grade 1 and tend to grow slowly, while higher-grade meningiomas may behave more aggressively and require closer management.
Symptoms of Meningioma
Small meningiomas may not cause any symptoms and are sometimes discovered incidentally during brain imaging. When symptoms develop, they may vary depending on the location and size of the tumor.
Common symptoms may include:
- Persistent or worsening headaches
- Seizures
- Weakness or numbness in the arms or legs
- Changes in vision or hearing
- Difficulty with balance or coordination
- Memory or concentration problems
- Changes in behaviour or personality
- Speech or language difficulties
Diagnosis of Meningioma
A detailed neurological examination and brain imaging are important for evaluating a suspected meningioma. Depending on the patient’s symptoms and clinical findings, investigations may include:
- Neurological examination
- MRI of the brain with contrast
- CT scan of the brain
- MR angiography or other vascular imaging when required
- Additional specialised investigations in selected cases
- Histopathological examination following surgery or biopsy
Treatment for Meningioma
Not every meningioma requires immediate treatment. The recommended approach depends on factors such as tumor size, location, growth rate, symptoms, grade, and the patient’s overall health.
Treatment options may include:
- Observation and Regular Monitoring: Small, slow-growing, or asymptomatic meningiomas may be monitored with regular clinical assessments and imaging.
- Surgical Removal: Surgery may be recommended when the tumor is causing symptoms, showing growth, producing pressure on the brain, or when removal is considered appropriate based on its location and characteristics.
- Radiation Therapy: Radiation may be considered for selected meningiomas that cannot be completely removed, recur after treatment, or have characteristics requiring additional treatment.
- Combined Treatment: In certain complex or higher-grade cases, surgery and radiation therapy may be used together as part of an individualised treatment plan.
Meningioma Surgery
Surgery is one of the primary treatment options for symptomatic or growing meningiomas. The surgical approach depends on the size, location, and relationship of the tumor with important nerves, blood vessels, and brain structures.
The goals of surgery may include obtaining an accurate diagnosis, relieving pressure on the brain, and removing as much of the tumor as can be safely achieved.
For tumors located close to critical structures, complete removal may not always be the safest option. In such cases, leaving a small portion of the tumor may be considered to reduce the risk of neurological injury, followed by appropriate monitoring or additional treatment when required.
Recovery After Meningioma Surgery
Recovery after meningioma surgery varies depending on the tumor’s location and size, the extent of surgery, the patient’s neurological condition, and overall health.
Some patients may resume normal activities within a few weeks, while others may require a longer recovery period. Patients experiencing weakness, speech difficulties, balance problems, or other neurological issues may benefit from rehabilitation.
Regular follow-up appointments and brain imaging are important after treatment to monitor recovery and identify any evidence of tumor recurrence or growth.

Frequently Asked Questions About Meningioma
1. What is a meningioma?
A meningioma is a tumor that develops from the meninges, the protective membranes surrounding the brain and spinal cord. Most meningiomas are benign and slow-growing, although some can behave more aggressively.
2. Is a meningioma a brain tumor?
Yes. Although meningiomas arise from the membranes surrounding the brain rather than from brain tissue itself, they are classified as tumors of the central nervous system and can affect the brain by pressing on nearby structures.
3. Are all meningiomas cancerous?
No. Most meningiomas are benign. However, some may grow faster, recur after treatment, or show more aggressive characteristics. The tumor’s grade and microscopic features help determine its behaviour.
4. Does every meningioma require surgery?
No. A small meningioma that is not causing symptoms and shows little or no growth may be monitored with regular MRI scans. Surgery may be recommended if the tumor grows, causes symptoms, or is affecting important structures.
5. What are the symptoms of a meningioma?
Symptoms depend on the tumor’s size and location. They may include headaches, seizures, vision problems, weakness or numbness, balance difficulties, speech problems, memory changes, or behavioural changes.
6. How is a meningioma diagnosed?
MRI of the brain with contrast is commonly used to evaluate a meningioma. CT and other imaging tests may also be recommended. A definitive diagnosis and tumor grade are established through examination of tumor tissue when surgery or biopsy is performed.
7. Can a meningioma grow back after surgery?
Yes, a meningioma can recur after treatment. The risk depends on factors including the tumor’s grade, location, extent of removal, and other pathological characteristics. Regular follow-up imaging helps monitor for recurrence.
8. Can a meningioma be completely removed?
Complete removal may be possible for some meningiomas. However, if the tumor is closely attached to or surrounding important nerves, blood vessels, or other critical structures, a safer approach may involve leaving a small portion behind and monitoring it or treating it with radiation when appropriate.
9. How long does it take to recover from meningioma surgery?
Recovery varies from patient to patient. It depends on the tumor’s size and location, the type of surgery performed, and the patient’s overall health and neurological condition. Some patients recover within weeks, while others may require a longer period of rehabilitation.
10. When should I consult a neurosurgeon for meningioma?
A neurosurgical consultation is recommended when imaging identifies a meningioma, when symptoms suggest a possible brain tumor, or when the tumor is growing or causing neurological problems. A specialist can determine whether monitoring or active treatment is appropriate.
