A meningioma is a type of tumor that forms in the meninges, which are the membranes that cover and protect the brain and spinal cord. These tumors are most commonly benign, meaning they are not cancerous and do not spread to other parts of the body. However, some meningiomas can be atypical or malignant, which means they are more likely to grow rapidly and may spread.
Symptoms:
The symptoms of a meningioma depend on the location and size of the tumor. Some people with meningiomas may not experience any symptoms at all, especially if the tumor is small and slow-growing. However, as the tumor grows, it can press on nearby brain tissue, nerves, or blood vessels, causing a variety of symptoms, including:
- Headaches
- Seizures
- Weakness or numbness in the arms or legs
- Vision problems
- Hearing loss
- Difficulty speaking or swallowing
- Changes in personality or behavior
