Overview Of Intracranial Tumors

Last Updated on

Some tumors are benign, but because the cranium leaves no room for expansion, even benign tumors can cause serious neurological dysfunction or death.

Intracranial tumors may affect the brain or other structures (eg. B. cranial nerves, meninges). The tumors develop usually in the early or middle adulthood, but they may develop at any age; the incidence is increasing in the elderly. Brain tumors are found in about 2% of routine autopsies. Some tumors are benign, but because the cranium leaves no room for expansion, even benign tumors can cause serious neurological dysfunction or death. Classification There are two types of brain tumors: primary tumors: originate in the brain either in the brain parenchyma (. Eg gliomas, medulloblastomas, ependymomas) or extraneural structures (. Eg meningiomas, acoustic neuromas, other schwannomas) Secondary brain tumors (brain metastases): originating in tissues outside the brain and scattering in the brain brain metastases are about 10 times more common than primary brain tumors. Tips and risks brain metastases are about 10 times more common than primary brain tumors. Cerebral metastasis Image courtesy of William R.
