Cerebral Hemisphere Tumors

Types of Cerebral Hemisphere Tumors:

1. Gliomas: These tumors originate from the supportive cells of the brain and can include astrocytomas, oligodendrogliomas, and ependymomas.
2. Meningiomas: Arising from the meninges, the protective layers surrounding the brain and spinal cord.
