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.
