Meningiomas are tumorsarising from the outer part of the arachnoid mater in the meningesof the brainor the spinal cord.

Meningiomas are slow-growing tumors of middle and old age that are usually dome-shaped, with the base lying on the dura. They are most frequently attached to the dura over the parasagittal or free hemispheric convexities, along the sphenoid ridge, in the olfactory grooves, and based on the falx cerebri. Some display a degree of calcification. The symptoms depend closely on the exact location of the tumor. Hence, a meningioma compressing the frontal lobecan give rise to frontal lobe syndrome.

Treatment

They can be usually surgically resected, and complete cure is possible. Malignanttransformation is rare. Depending on the location and nature of the tumor, doctors may use neurosurgeryor radiosurgery-- or they may carefully watch it over time, seeing if it grows. There has been some reported success using the drug hydroxyureafor meningiomas, but trials have not shown it to be effective on most cases.
