Brain Tumors II
Ependymomas – appear at the lining of ventricles and usually manifests in children and adolescents.
Oligodendrogliomas – are rare tumors that develop in cells that produce myelin. These tumors grow slow and do not usually spread in the surrounding areas of the brain. It manifests mostly in middle-aged adults.
Other tumors that do not develop in glial tissues:
Meningiomas originate from the meninges, the membranes surrounding the brain and spinal cord. These tumors grow very slowly and are usually benign. It occurs mostly in women at ages 30 to 50.
Creniopharyngiomas develop near the pituitary gland and the hypothalamus. The tumors are usually benign, but are considered malignant when it grows in size and creates pressure on the surrounding brain tissues which may damage and affect vital body functions.
