Meningioma is a condition in which tumors arise in the meninges, which are the membranous layers that cushion the central nervous system. The exact cause for their occurrence is not well understood, though genetics are known to play a role. A meningioma is typically small in size, though a small percentage grows to be large. The smaller tumors tend to be benign and may not even produce any symptoms through the course of one's lifetime. However, in some cases, when the meningiomas are large or malignant, symptoms manifest and may be treated using radiosurgery or conventional surgery.
People with meningioma tend to suffer from headaches very frequently. They may experience them several times a day, with temporary relief coming from over-the-counter painkillers. Headaches often occur because either the tumor is on the surface of the brain or in the intraventricular region. In the latter instance, the tumor blocks the flow of cerebrospinal fluid, thus causing the pain, which is typically a dull throb or a nagging heaviness.
