A 55 year-old woman presented with headaches and a right VI nerve palsy.

Note the Isointense Tumor on  T1                         Show the Gadolinium Enhancement                        Outline the Carotid Arteries

MRI Scans (Left Upper) T1-weighted axial; (Middle) T1-weighted axial with gadolinium; (Right) T1-weighted cornonal with gadolinum. Note the well demarcated mass which is dural arising from the region of the right cavernous sinus. The mass is isodense on T1 but strongly enhances with contrast. The flow void of the carotid artery is seen with the lesion. Meningiomas are common tumors.  They are typically benign histologically, and treatable with surgical resection if they are in an accessible location.
