(Left) T1-weighted with gadolinium sagittal MRI; (Right) T1-weighted with
gadolinium coronal MRI. Note that on the
coronal and sagittal scans, it is clear that the mass is dural based, arises
from the sphenoid bone, and grows up into the frontal lobe. Meningiomas are common tumors that arise from the meninges and can occur within the spinal canal as well as intracranially. They are typically benign histologically, and can be surgically resected if they are in an accessible location. They are more common in women than men, and account for approximately 20% of all primary brain tumors. Similar to low grade gliomas, they grow very slowly. They may result in seizures, focal neurological signs, or both, depending on their location. Some of the more common locations for meningiomas include: ● Parasagittal (attached to the falx) |
