MENINGIOMAS

---

A brain meningioma is a type of tumor that forms in the meninges, the protective layers of tissue that cover the brain and spinal cord. Although these tumors are usually benign (non-cancerous), they can still cause problems due to their location and size.

Meningiomas are the most common type of brain tumor, accounting for about 30% of all brain tumors. They are more frequently diagnosed in adults, particularly women, and the risk increases with age. However, they can occur at any age.

The symptoms of a meningioma depend on its size and location in the brain. Common symptoms include:

• Headaches
• Seizures
• Vision problems, such as blurred or double vision
• Hearing loss or ringing in the ears
• Memory loss or confusion
• Weakness in the limbs or face
• Difficulty with balance or coordination
• Personality changes

Diagnosing a meningioma involves several steps:

• Medical History and Physical Exam: Your doctor will review your symptoms and perform a neurological examination to check for any changes in brain function.
• Imaging Tests: MRI (Magnetic Resonance Imaging) or CT (Computed Tomography) scans are used to create detailed images of the brain and identify the presence of a tumor.
• Biopsy: In some cases, a small sample of the tumor may be taken and examined under a microscope to confirm the diagnosis and determine the type of cells involved.

Treatment for meningiomas depends on the size, location, and growth rate of the tumor, as well as the patient's overall health. Options include:

• Observation: Small, slow-growing meningiomas that aren't causing symptoms may simply be monitored with regular imaging tests.
• Surgery: If the tumor is accessible and causing symptoms, surgical removal is often the best option. The goal is to remove as much of the tumor as possible without damaging surrounding brain tissue.
• Radiation Therapy: This treatment uses high-energy beams to target and shrink the tumor, often used when surgery isn't possible or to treat any remaining tumor cells after surgery.
• Medications: In some cases, medications may be used to manage symptoms or control tumor growth.

There are various surgical techniques for removing meningiomas, depending on their size and location:

• Craniotomy: The most common approach, involving an opening in the skull to access and remove the tumor. This method allows the surgeon to directly view and carefully remove the tumor.
• Minimally Invasive Surgery: For certain tumors, minimally invasive techniques using smaller incisions and specialized tools can reduce recovery time and minimize risks.

Early detection and treatment of meningiomas can lead to better outcomes and improved quality of life. If you experience any symptoms or have concerns about meningiomas, it's important to consult your healthcare provider for a thorough evaluation.
