A 55 year-old woman presented with a weakness of both legs and difficulty walking. A spinal cord lesion was initially suspected.
MRI Axial Scans: (Left) T2-weighted; (Middle) T1-weighted; (Right) T1-weighted with gadolinium. Note the large midline mass which is compressing the adjacent medial frontal lobes. The mass enhances with contrast. This is the 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.
