A 75 year-old woman presented with a change in personality, memory loss, headaches and a mild left hemiparesis.
MRI Scans (Left ) T1 axial; (Middle ) T1 axial with gadolinium; (Right) T1 coronal with gadolinium. Note the large, well demarcated mass. The tumor is dural based and compressing the adjacent temporal lobe. The mass is isodense on T1 but strongly enhances with contrast. 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.
