Meningioma
Meningiomas are tumors which arise from the arachnoid "cap" cells of the arachnoid villiin of the meninges. A meningioma can occur at any age but it usually occurs in adults. Most meningiomas are benign; it is rare that a meningioma is malignant.
Usually, symptoms and signs of a meningioma are not significant. They start gradually and most may be very subtle at the beginning of the disease. For a small meningioma which does not cause obvious symptoms or signs, treatment is not necessary, and periodical observations may be enough. Symptoms and signs of large meningioma depend on its location and size. The followings may occur in a meningioma:
- Focal seizures
- Headaches
- Vision disorder, such as double visions and blurred vision
- Weakness legs or arms
- Memory loss
- Hearing loss
Options for treatment depend on the size and location of the meningioma, the nature (benign or malignant), the overall health condition, and personal preferences.
- Surgery
- Radiation therapy
- Chemotherapy
- Observation (in case that a meningioma is small and asymptomatic)
- Stem cell therapy
