Show the Tumor     Show the Gadolinium Enhancement

(Left) Axial MRI Scan T1 weighted; (Middle) Axial MRI Scan T1 weighted with gadolinium; (Right) Coronal MRI Scan T1 weighted with Gadolinium.  Note the large, well demarcated mass which is dural based and compressing the adjacent frontal lobe.  The mass is isodense on T1 but strongly enhances with contrast.  Also note the large area of surrounding edema and associated mass effect. On the coronal scan, one can better appreciate that the tumor arise from the falx and has grown into the left frontal lobe. However, as it has enlarged, mass effect is also present on the right frontal lobe. This is the typical appearance of a meningioma.  Meningiomas are common tumors.  They are typically benign histologically, and treatable with surgical resection if they are in an accessible location.
