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 lobe can give rise to frontal lobe syndrome.

Treatment

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