CONDITIONS WE TREAT

Meningiomas are the most common benign tumors of the brain (95% of benign tumors). However they can also be malignant. They arise from the arachnoidal cap cells of the meninges and represent about 15% of all primary brain tumors. They are more common in females than in males (2:1) and have a peak incidence in the sixth and seventh decades. Most cases are sporadic while some are familial. There has been some evidence that persons who have undergone radiation to the scalp are more at risk for developing meningiomas. Meningiomas are readily visualized with contrast CT, MRI with gadolinium, and arteriography, all attributed to the fact that meningiomas are extra axial and vascularized. CSF protein is usually elevated if lumbar puncture is attempted.

TREATMENTS

Meningiomas can usually be surgically resected with permanent cure if the tumor is superficial on the dural surface and easily accessible.
