Mean age is 45 years (peaks approx. 65 years). Women twice as likely as men to have diagnosis
Meningiomas originate from arachnoid cap cells located in the leptomeninges, are extra-axial (does not invade parenchyma) and typically benign
Common locations are cerebral convexities (44%. parasagittal, falx) and sphenoid ridge (12%)
Radiographic Studies for Meningioma
MRI, with and without Gadolinium: Utilizing images with both non contrast and contrast will allow the clinician to wholly evaluate the lesion and surrounding edema.
Cat Scan: Useful to evaluate adjacent bone involvement of meningioma, also known as hyperostosis
Angiography: Not useful for evaluation of meningioma
I will flesh this section out with various meningiomas as the year progresses, based on our referrals and surgical consultations
