Meningioma - Definition

August 2017


Definition


Meningioma is a benign tumor that usually develops in the meninges, especially in the arachnoid cells. The meninges are three membranes covering the brain and spinal cord, and play a role in protecting the central nervous system. Meningiomas may well occur in the brain but also in the spine. The causes are still unclear, but these tumors mainly affect adults after the age of 40, especially women. Symptoms vary depending on the location of the meningiomas: headaches, epileptic manifestations, and impaired vision for those affecting the brain, pain in the arms and legs, and even a loss of sensation or paralysis of part of the body for those affecting the spine. After identification by CT scan or MRI, it is necessary to operate to remove the meningioma and the prognosis is generally good.
